 So, welcome back after the feed break. So, this section is a feedback session with a valedictory function. So, we will have a guest coming in later at 12.30 to conclude the workshop, but until that time this is a feedback session which is open for feedback. So, two rules here one is you are free to ask any question, but I will insist that you tell something about the workshop give us some form of feedback. So, you could ask a question, but in addition to this you should also comment on the workshop like how did you find the workshop if you had any faced any issues you could share us with us if you have any suggestions also you could share with us. So, whether or not you have a question related to the concepts or labs or any other thing we do want to hear some feedback from you. So, that is the rule number one. The rule number two is we would ideally like to give priority to those remote centers that have not had an opportunity to ask a question so far. So, if you have already asked questions in the past please refrain for some time before pressing the hand button to ask a question. We will like the ones who have not been given an opportunity so far to ask a question to take precedence. So, others please refrain the ones who did not have an opportunity so far please press the hand button. Good morning ma'am. On behalf of Siliguri Institute of Technology myself Suthapa Bhattacharya are really very thankful to IIT for organizing two week ISTE workshop on computer networking. Most of us having only theoretical concept of networking but this workshop provided us practical as well as theoretical concept. The concept of Bodhi tree to teach and reach faculties are understanding. The Bodhi tree reaches us with excellent materials. We also want to mention the talk of Professor Sridharayar and Professor Bhaskaran Raman. Their session was excellent also. We are really happy to know the IIT is very much concerned about to teach us thus how to teach different subject properly with different methods. The lab sessions were really very good but we expected some more details explanations on NS2 and socket programming. We faced some difficulties to solve last two days lab assignment apart from all these things we are mesmerized to your knowledge what are sharing to us and your presentations. Okay, thank you for your feedback. We'll definitely as I said it's an ongoing process. We do want to add on more material to make it more user friendly. Definitely more material on the labs is forthcoming. So yeah once we have the material we will again reach out to you all and share the material with you and thank you for the very nice feedback. My question is related to research topic. What is the research scope in fast TCP? Fast TCP. Yeah. See if you define fast TCP then there is no research scope. As I said TCP there are a lot of variants of TCP but as I said TCP is also another area that is more or less beaten to death. There are all kinds of work has already happened. Coming up with something new in that space I think is very difficult. So there's always some tweaking of something here something there but it's all incremental work but that said there is still work that happens. So for example in the recent sitcom the conference that I have mentioned there are some papers on TCP how to improve the performance of TCP in different settings. So you should read up on some of the recent papers that come up in some of these good conferences then you will get to know what is the research work that happens in TCP. But as I said unless somehow it so happens that you came up with a great idea in that space it's very difficult to come up with something new in that space since lot of work has already happened on TCP. I have another question. Quality of the practice quizzes was very acclaimed. Can we get some question from that practice quizzes in a single file? Yeah this I had already mentioned we do not want to give away all the quizzes like that because we do want people to use the platform otherwise there is no reason for anyone to use the platform. Yeah the MP4s are free quizzes are not free sorry about that. Very good morning ma'am this is RC 1249 Sri Ramakrishna Institute Technology Coimbatore Tamil Nadu myself Praveen Thraja and we attended so many works up under IIT Bombay DPMS computer programming but this computer networking is a wonderful works up because introduce a new like bothy tree it is a very useful and also it is a new technique to handle the theory as well as the practical part so we enjoyed a lot for the last one week so thank you very much for introducing this new technique ma'am and also on behalf of Sri Ramakrishna Institute Technology Constable Managing Trusty faculty members we show all the best for completing your assignment on the multimedia textbook thank you ma'am. Okay thanks a lot for your very nice feedback definitely I mean it feels good to know that the amount of effort you have put in people are appreciating it but that said if you have criticism also please feel absolutely free to share because one improves only via criticism you can't just feel good about the good things one has to feel a little bit bad about what you have done that's when you improve further so I mean this is an open remark for all the remote centers it's definitely feels good to get good feedback but if you have issues or something you like to criticize about it I'm not going to feel bad about it so please by all means share your criticisms as well thank you my question is for socket programming is it better to use the C or C++ or to use the java program which one is better so as I said you could do socket programming with either you could use java or C++ C++ gives lot of the internal details become more evident to you because java hides many of these internal details it provides just very clean APIs for you to use so it's a so I would say whatever it's more important to learn how to do socket programming so whatever you are comfortable with if you feel you are comfortable in with java just get started with it you're comfortable in C then get started with it if you're comfortable in both then I would have a slight more preference for C just because it gives lot more detail not only that if you are going to go into more advanced coding then java doesn't expose what are called raw sockets these are very useful if you are doing I mean this is an advanced concept also but certain things are not exposed via java so if you really want to use some of these things then C++ is the way to go but for a beginner either is fine whatever makes you comfortable very good morning ma'am very good morning the best thing in your workshop is your the video lectures which you have provided on the bodhi 3 but I would like to give you a bit of selection suggestion can you please embed the national anthem in the morning session of every day yeah we will give that suggestion to the people workshop staff yeah I will I'll pass that information to them because obviously you do start every lecture of appeals with a prayer so why can't with the workshop sure sure I'll pass the feedback to the concerned people thanks for that ma'am hello ma'am yes first of all I would like to thank you for organizing this workshop it has helped us in learning a lot of things just one complaint I would have is that there should have been at least one session on ns2 and socket programming so that it would have helped us in doing things better and in implementing things better and regarding today's lecture I have just one question is that is when you spoke about MPLS what information does this MPLS tag contain and how does it improve router speeds and ensure or improve quality of service okay regarding your first question about ns2 rather feedback on ns2 and socket programming the material has already been put on bodhi tree there are videos on ns2 including a demo of it as well as socket programming the expectation was that you would have watched those videos before attempting the exercises so from my side I think I did put them up so maybe majority of you or maybe some of you have not gone through it before the exercise yeah and does make it difficult if you don't go through them regarding your second question on MPLS the tag basically contains the virtual circuit identifier the label if you know the concept of virtual circuits you identify a flow with a label the same similar concept is there in MPLS except that it's not an individual flow you could identify an entire IP prefix with a label so it's more sophisticated than regular virtual circuit switching these are called forward equivalence class so you could define some such class based on some criteria and bind many flows to the same label so that is one big advantage of MPLS the speed up of MPLS that is achieved is as I said earlier typically in datagram networks you use the longest prefix match which means within your routing table which in a core router could be millions of such routing tables there may be multiple entries that match so search is the algorithmic search is lot more difficult it takes more time whereas when you use a label you could view the label as an index into your routing forwarding table so you just need to suppose if you are maintaining it as a form of an array you are basically telling this entry is at position 2032 in which case you just access it there read out the label and interface outgoing label and push it so it makes things much faster the concept of f forward equivalence class as I have mentioned is used to implement traffic engineering and thereby quality of service how it does it as I said involves lot more detail I cannot go into it in the interest of time usually the video transmission is done through VBR variable bit rates right but the nature of video is a streaming that is mostly streaming protocol or use it all why you why we use the VBR why not CBR can you explain it yeah so the nature of video is like that the so for example if you are watching a movie some scenes are very static like there is not much stuff happening whereas some action sequences for example where the hero is hitting the villains or whatever it is there is lot of motion so it is inherent in the nature of video to generate a variable bit rate stream so over time the amount of bits to capture the action on the scene are going to vary so thereby it produces a variable bit rate video but to some extent these issues are handled through this playback buffer so you do not play the video right away you buffer the content to some extent and then start to play mean the hope that some of this variability gets averaged out and you won't see this playback problems when you are playing the video because the buffer tries to smooth out some of the variability in the incoming traffic another question is is actually the we face a problem when we go for the get the contents from the site why you you didn't use the youtube as a private channel for the accessing these videos see as I said I wanted this is a multimedia textbook I wanted a structure imposed on them I wanted the quizzes to go along with the concept I want slides to be there I wanted to monitor your performance there are many things I wanted to do as part of the platform we really wanted to test it out at such a scale see what's happening so that's one of the reason in fact the reason that platform was developed is to impose such a structure in the textbook as well as to monitor the progress of the students youtube actually doesn't give any of this that said finally when we face these problems we could share the videos instead of a google drive I could put it up on youtube I just didn't do it just I mean I don't know youtube I have never uploaded videos there is some learning curve it just was easy for me to share with google drive I didn't give it much thought this is Vidya from remote center 1303 Srinayana Guruvillam College of Engineering Kerala and we have a question like in the transport layer we have different versions of TCP like TCP Renault Tahoe QBQ etc what would be the general TCP version commonly used in real time systems so typically the real time systems use TCP stack the selective acknowledgement option of TCP most of the real time systems use that regarding the feedback actually ma'am your talk about future trends in computer network was really good and some of our faculties I hope they would be able to identify areas in computer networks for their research and think fair share by Sridhar Iyer was really helpful and the flipped classroom concept I think we don't really able to implement because we are having a predefined method of teaching but as far as from your perspective the classroom was really good and the lab session I hope we got a really wonderful hands-on experience with the NS2 wire shark as well as TCP dump your writing tips by Bhaskaran Raman was also good we wish you and your technical team best of luck for your future projects thank you ma'am okay thanks a lot for your feedback first of all I want to thank you briefly for your wonderful programming training scheme and I would like to thank Mr. Iyer for the team fair and fair scheme and Mr. Bhaskaran for the team on perfect handling system and this training program for the good thing that the teachers can gain some knowledge to express their knowledge and everything to get a new thing to their life so and I would like to all the staffs for participating this thing and my question is that in during the serial data transmission for transmitting the different numbers of data if one packet will be lost and it will be transmitting through the different numbers of half node and what will happen in the receiver side and what is the role of the half node during this transmission so when you're thank you for your feedback and secondly when you're sending a bunch of packets yeah if a packet gets lost and if the packets are taking different paths what this manifests at the receiver is you could get out of order packets so for example you send one two three four you may get one two four three or some packets internally I mean some packets like two could be lost in which case you will get one four three something like that can happen at the receiver so most of the depends upon the context so if you are doing some link layer link layer protocols like ARQ at that level which normally Ethernet doesn't support so let's talk about the internet within the internet often this is handled at the transport layer so the transport layer will reorder the packets as well as recover from the lost packets through retransmissions put them all in order and then pass it to the application layer so that is being handled by the protocols within the internet to ensure that even though many such things can happen you still have mechanisms in place to overcome them at the appropriate layer which is often the transport layer I'm very much happy to attend this workshop and after attending this workshop I have a great interest to research on this topic after listening to you and different professors I'm somewhat excited to attend this program my question is ma'am how the five layers are installed in the system whenever we are connecting internet then that is transmitted to these five layers so how these layers are installed in the system so as I said all these layers except application level is a user level thing you run it as processes so you can run any application you could for example you wrote that send udp.c you executed it and you ran it so that's all being done at the application layer that is something which you could do that is what we call runs in the user space applications but anything below it which is the transport network link drivers all of them are implemented at the kernel space so these are implemented as different modules which get loaded on you could for example if you change your network card and you install some other card it can come with another driver so you load that module so that you can control so all this is in the kernel space so unless you do some kind of kernel programming it's not easy for you to get access to this code so if you want to know internally what is happening you should read some books on kernel programming then you will know what is happening internally within a host I would like to thank you ma'am for patiently hearing the questions and answering the same and I would like to give the feedback regarding the lab we are experiencing here very new aspects of computer networking and we are enjoying the packet delivery packet transformation and dropping out of the package so thanks a lot for showing us and making us aware of new aspects of this computer networking thank you ma'am okay thank you for your feedback hello yes go ahead thank you and your team for the excellent material that you have provided online and I'll show also the clarity and the quality of the video that you have provided is very good so whatever input you have given during these things actually really it has helped us to sharpen the knowledge we have and so that we can also distribute the same knowledge to the students which will help them to understand it better the concepts and even in the practicals but at the same time so expecting maybe in the future some more practical materials and also some concepts in the advanced computer networking if you can have so that will be great for us it will help us to a great extent in later point of time and also at the same point of time I'd like to ask a very general question ma'am so basically when you talk about computer networking there are two approaches one is a top-down approach what exactly in the IIT you follow for teaching the students and also what you think the best approach to go for the students to teach so that they can learn better okay thank you for your feedback definitely I had mentioned this before also we do want to add on more material to the current concepts add more labs also to the current concepts so this is an ongoing thing as and when we add we will share it with all of you that said coming to your second question related whether top down or bottom up is better I personally prefer bottom up because of two things one is application layer I feel I I mean I have this generic feeling that it doesn't have any major concepts like anything related to computer networking the concepts are at the link layer network layer and the transport layer so application layer kind of doesn't have much concepts for so when you start from the top down you spend a lot of time on teaching the different applications but it doesn't give you much concepts the other reason why I prefer to go bottom up is it also gives this very building block layer approach to teaching so you start with how to communicate just between two hosts then you build how do you communicate between tens of hosts then you tell how do you communicate between thousands of hosts which is the extended line then you talk about tens and thousands of hosts which becomes the network layer so it gives that kind of a very structure to it but that said so when we teach our own CSC undergrad students we do bottom up just because we can get to spend lot more time so when you start with the application layer what happens is the first three four weeks go there so the amount of time left for the bottom layer gets kind of squeezed when you do bottom up you spend lot more time on the relevant concepts and then you can squeeze in the application you could decide to skip some applications if you there is no time or add on if there is time so it gives some flexibility like that but when I teach so we do teach computer networks to other department students also for example metallurgy is the institute level course we offer whenever I teach them I do top down because when it comes to other department people they do not really need a lot of in-depth concepts they are coming more as a users of computer network they are more interested in how the applications work and provide just an overview of the network transport and link layer so there we spend lot more time on the application layer and little bit less time on the lower layers so that is how I do it it is a personal preference as I said up to you whatever logic appeals to you yeah mom actually if you go for a bottom-up approach so in that case basically as far as the lab is concerned so from our side from my experience I am telling so sometimes we face difficult in the lab so because if you go start from physical layer then what are the sort of lab we can conduct as the beginning for the students okay so even for that so again the way so I do it bottom-up and there is an associated lab for it so this is typically what I do the very first so as you saw even in my lectures there is an introduction that talks about OSI protocol stack the interlayer communication this is fundamental so the very first lab is more or less identical to your lab one and lab two so the ones that you have done multiplexing demultiplexing encapsulation all that is part of our lab one here the second lab again I do that as you saw I also measure I also have a concept in introduction on goals and metrics which talks about what are the goals of computer networks how do you measure delay latency packet loss blah blah so my second lab is on NS2 that deals with those concepts so which is basically they get a grounding in the introductory material they understand what delay is what losses are what is packet stream so on so forth and through the first lab which is on encapsulation they get to know the OSI protocol stack well and from that point on so the third exercise which I often give is this torchlight based communication which is basically dealing with framing error correction error detection where they have to design things on your own you could also do for example NS2 based on CSMA CD type of exercises so you could measure what the throughput is as users are increasing so on so forth so that's where link layer some of the ARQ mechanisms through simulation all of them can be incorporated as part of NS2 or as implementation the torchlight based communication then you cut to the network layer again network layer you have seen some of the labs ARQ based DHCP based we also have labs using a tool called BNU ML which lets us do bridging which lets us do IP configuration misconfiguration of IP addresses subnet mask assignment so on so forth so we do all this as a network layer and then once we get to the transport layer again we use some simulator NS2 to do the TCP level analysis TCP Reno versus new Reno or TCP Tahoe versus Reno that kind of TCP level and when we come to the application layer we basically ask them to do some project based on socket programming so that's how we go bottom up actually so if you can give a list of experiments and do some details to which to be followed as far as your TCP I mean bottom up approaches tension that will be really help us see whatever exercises I could do I already shared with you the other exercises dealing with network configuration as I said involves this VNU ML tool which is a nightmare for us itself to install so I I mean I absolutely cannot provide any support to if you somehow figure out how to install it on your own I can give you additional exercises but that installation is a very tricky installation it doesn't work very easily ma'am we are much beneficial from IIT workshop that avails at our doorstep this remote center so I was beneficial through the first workshop organized in 2009 by IIT Mumbai that is SDS since our January was started from that workshop and today's test will continue and in future going to be continued so ma'am at this moment I wish to share my my output that here in this workshop this workshop excellent in terms of different concepts we having like in fair and fair flip the platform and ma'am but the most expected from your and that that is our workshop should be majorly focused on issues in different technology like in computer network networking programming and other ma'am my question is that what are the current development in 128 bit encryption of SSL protocol and second question is that now what are the utility of RU pay payment gateway gateway recently launched by the government of India ma'am so your first question is on SSL 128 bit okay that's a security thing as I said I have very minimal background in security so I don't want to handle any security questions now your second question I did not quite get government has initiated what are you pay payment gateway payment gateway like visa and government of India launched are you pay payment gateway actually I don't know about it so I have to I cannot comment because I'm not aware of what this gateway is ma'am I would like to know that if two different wireless technology can be converged or not means if I need to send one packet from Wi-Fi and I am getting the same packet from another terminal which is having a Bluetooth then this convergence is possible or not and if it is possible then we charge the tools necessary to successfully this convergence so currently each technology for example Wi-Fi defines its own physical layer its own media access control Bluetooth has its own physical layer its own media access control so it's like two people talking in different languages so you cannot understand what the other person is telling though you could detect their energy so Bluetooth can detect Wi-Fi's energy if it is transmitting in the same spectrum but you cannot interpret any of the bits because it's following something different modulation scheme which you don't know how to demodulate so currently definitely it is not feasible for them to interact in the fashion you suggested so for any modulation technique that you use the receiver has to use an equivalent modulation technique for it to interpret the data to some extent with the use of these things called software defined radios where you configure the radios based on parameters so at the receiver for example you know you have the sender has used modulation 1 it could potentially in software load that modulation and decode it but that's slightly I mean there is work happening in that space but the radios are pretty expensive so anything currently let me just conclude that you cannot make them both talk with each other in the fashion you have discussed you try to make any mediator device which can be convert from Wi-Fi to Bluetooth from the same server and then configure both the device with the same server then it is possible or not so it depends on what you are doing for example you want to send a packet from Wi-Fi to some other user who is sending a Bluetooth so you could send this Wi-Fi packet to another intermediate host which has a Wi-Fi interface based on which it will decode the packet it will send up the protocol stack and then you are again using this intermediate host has two interfaces one is Wi-Fi another is Bluetooth then it will again come down and go out via the Bluetooth interface that is feasible so it's something like in the common language you have a translator who understands both languages who is sitting listening translating it and passing it on the other end for that which tool is useful there is no tool you have to write you have to do the implementation you have to set up a host that can have two interfaces there is nothing readily available like that you have to set it up so we have here professor Patak as well as professor Gaitonde so I will request them to please come here and give some concluding remarks of the workshop good afternoon and I am very happy to welcome professor Gaitonde who has been my colleague for almost four decades and with me he has been a great participant and supporter of this T10KT program and with me he is also embarking on a new journey of offering some of our courses as massive open online courses first through EDX and maybe later on an Indian platform so welcome professor Gaitonde please have a seat before handing over to professor Gaitonde and requesting him to say a few words as a valid address I thought I would like to go over to a few remote centers myself but please don't ask me any questions on networking that is the domain of professor Kameshwari but I would like to have any general feedback about the workshop and how you have benefited you can go to two or three first of all I would like to say that I am removing all the hand raises that have been raised so far and I would like to request only those remote centers which have never interacted with us at all during this workshop never interact they did not get a chance to interact at all and I would like only those remote centers to raise hands and then we will go on first come first serve basis so I am requesting my colleague to remove all raised hands now and I request only those remote centers which are never interacted to raise hands can you can you clear up Reenaatji Institute over to you for some comments good afternoon please go ahead good afternoon sir first of all I want to thank IIT Mumbai this workshop was very fruitful as well as the students we got a lot of knowledge about networking especially the board triple platform as flip class flip classroom is very active we will definitely implement this concept from this session thank you sir thank you go to the other centers good afternoon sir good afternoon on the behalf of Maman IIT Bhupal I am Sanjeev Sharma we are very thankful to you sir for organizing such a very great kind of workshop for us especially I am thankful to you to provide the material that was very good quality material and the approach that you are provided a practical approach for the capital networks because before this workshop we are not aware of such a kind of practical approach in the capital network so your quality of the material was very good and the course was very very good the assignment that you have provided was very good and especially this workshop provides us to interact with the experts and all of the remote centers are interacting and they are raising the questions so it is also clearing our various doubts regarding the subject so we are very thankful for organizing such a kind of workshop sir thank you thank you I will just comment briefly while he goes to the next remote center you mentioned that the approach was very practical well first of all Professor Kameshwari is to be complimented for making a very rigorous set of tools available to all the remote centers where you can do experiments but I would like to mention that there cannot be good engineering education unless there is a lot of hands on and what you mentioned raises some concern in my mind from old times that in many of our colleges most subjects the teaching concentrates on theory teaching whereas corresponding hands on experience in the lab is absolutely vital for students to understand proper problem solving so I am glad that you mentioned that and I hope you and all other colleagues across the country would actually adopt this approach in their teaching let us go to the next remote center please this Thakur College of Engineering the sessions were very good especially the lab sessions we got a very good knowledge and the videos which were uploaded were very nice and the quizzes were a little bit difficult but if you try to attend you can go for it and thank you very much so the observation by the lady that things were a little bit difficult I will tell you the approach and philosophy of IIT education and I feel no reason why the same cannot be adopted everywhere else our students are routinely given only a chance to answer simple questions our examinations also contain simple questions these fail to challenge the minds of students it is wrong to assume that if the students do not have adequate preparation they will not benefit from attempting to solve difficult questions this is another advice I would like to give to all the colleagues that whatever question papers that you said whatever quizzes that you said please ensure that there are at least some very challenging questions including some which even you cannot solve easily that is the way to challenge the minds of the students and you will find unbelievable improvement in the general learning of all students thank you for that comment let us go over to center 1271 Jawaharlal Nehru national college yeah over to you good morning sir regarding the tps implementation is somewhat tough to us implement as per our syllabus I govern by vtu and the technical education board tps implementation is not implementation is somewhat tough as well as coming to a classroom not going to work as we have but outcome based education so all the things are we need to have another option for these kind of things and apart everything was fine we have worked too much good too much well in the labs as well as I missed on all thank you sir thank you very much my observation is that independent of which method of education your university follows or independent of the scheme of teaching learning useful material in any subject can always be used innovatively by the teachers to benefit their students so please do not tag any of our efforts or any other efforts in the world as being compulsorily attached to a specific model of teaching and learning it is what is important is all the basic notions are discussed practical implementations are discussed students are challenged with the problems and then no matter what kind of education system you follow you should be able to use these basic building blocks in your own teaching thank you so much let's go over to another remote center sir this is Manoj Yadav from Dronachar College of Engineering we are thankful to IIT Mumbai who given us such type of important things about the computer networks and our participants they have learned a lot from this workshop thank you thank you one and all sir thank you so much remote center one three four two good afternoon sir am I audible yes you are please go ahead sir first of all I would like to thank the team IIT for conducting such a very nice good workshop although there is very good quality of the content moreover I would like to ask that there is one scope about the improvement here there is the video lectures that you had played the audio quality was not appropriate second thing all the live sessions the quality of all the live session is very good and I would like to request you kindly provide us the video of all the live sessions that held during this five days workshop if it is possible kindly upload on the google drive most important a very good huge round of applause for all the experts especially Dr. Deepak Fatak, Madam Kameshwari, Dr. Ayur, Dr. Bhaskaran and a very very special thanks to the technical team of Mr. Sushant so thank you very much sir thank you huge I would like to ask all my participants to have a huge round of applause thank you so much we will be uploading these videos not on google drive but there is a standard site on which all these videos are uploaded I will request Sushant to make note of the fact that not just the lecture videos but the interaction videos should also be uploaded this will be done in due course of time as you are aware we always release all contents in our T10KT workshops in open source so that not only the participants such as you but even other students and teachers can benefit thank you very much for that suggestion we will go to one or two more institutions J.S. College of Engineering Kalyani a very good afternoon sir this is Soham Sengupta from J.S. College of Engineering remote center 1335 so first of all I would like to thank on behalf of all the participants from the center to IIT boy and especially the speaker professor commissary for holding such a big event and which was really I felt it was needed because for the last 10 years of my teaching I have been digging into networking and everything so I have always felt the need to make the students feel the necessity of the what should I say that the TCP IP stack they feel the stacks are just the figures on the textbooks so what I do is quite matched with madam's you know frequency so what I make my students do is to explore themselves the stack by using worship tool and also I use them to get on to hands-on with a wind PC cap uprooted by Intel on which they can use a socket or a half web socket programming which makes the underlying things so thank you so I'll brief up things things that could have made this event a bigger one and more prosperous one first had we got chances to work hands-on with worship not only worship but also packet generation tools like it's cap and second which had been better if we could get some more time to know get in the into the programming of a kernel of a Linux to make a custom TCP stack and third was I felt this AV software is sometimes making a lack of synchronization because I think the software is using web socket technology which is not properly synchronized to use the user interface and that's all from my side as I hand the mic over to my colleague. Hello I want to stress that this workshop was extremely well organized and we all congratulate you and thank you for that. My next request would be to continue a line of communication between the centers and the coordinating body so that if we have any other queries in future we can always raise that in a forum. Secondly we would like to request if there is any scope for collaborative work between the centers and IIT Bombay under your mentorship. Very good points all I just briefly commend you see if you are not able to work on wireshark sufficiently it would be true about many other tools and that's the whole point the whole point is that each one of you when you go back to your own respective colleges don't stop that is where you start working actually get a group of students who are interested introduce new lab practical sessions introduce new BTEC projects or BE projects and continue to work with them in fact working in isolation you will discover many facets on your own which will be both challenging and more rewarding of course you can always interact and to answer to the question from the point from our other colleague we do propose to keep the moodle on for quite some time however you must appreciate that the moment this workshop is over like you professor Kameshwari also has about 1000 other things to do don't forget that she was awarded the excellence in teaching award of the institute which is a very rare award and which means that once the semester starts 24 by 7 she will be working on that I am proposing to the institute and to the ministry that we could keep a set of teaching assistants regularly attached to the moodle over coming semester in a year who could perhaps answer these questions who could perhaps classify them and some unanswered questions could be forced up to professor Kameshwari who could then release a single video lecture for anybody to watch where she might want to answer those questions do you think that makes sense yeah I do agree that this communication should go on further because I am also interested in the space if there is anything you could potentially use so we will look into seeing maybe moodle is the way forward so you could post things there they'll be brought to my notice and I will get back to you based on what the question is and what the requirements are I'm personally interested in it I would like to add more concepts to the video add more lab exercises to it and if as you as a remote center we are also collecting this post homework where you're supposed to create resources so during that process if you have certain ideas and you want to create additional labs and come up with that we could collaborate on that aspect as well so the communication line definitely from my side is open though it may not be a direct communication line but I'm interested in the space so any questions I will definitely pay attention to them whether I will act on it is will be a function of my life at that point what priorities I have but I'm definitely interested so if it's something that is interesting I'll definitely interact and collaborate we are going to Don Bosco Gohati first of all I would like to thank the entire team of IIT Mumbai for you know conducting this tremendous practical oriented workshop and also I would like to thank our remote center Don Bosco and thank to Kameshwari for you know designing such a good and very helpful course for the teachers thank you all thank you so much we just go to one more remote center and then we'll close this over to you. Hello sir. I'm Ajita from Moms & Queens Tamil Nadu and we are very thankful to you and your teams especially ma'am professor Kameshwari ma'am she introduced it some of the it was very well and and she today morning she went on with some modern trends in networking also that was too good and we would like to have something sir we'd like to have an open source tool for cloud implementation very interesting that you ask this question IIT Bombay as we speak is involved in implementing an open source cloud it's called the open stack model there are a few implementations already around the world as I said as we speak we are trying to implement it in fact the MOOCs platform for Indian usage that we are adopting from EDX is likely to be installed and deployed on an open stack model so that is the open open source cloud for you as we learn more about it we'll share that information also thank you very much for bringing it up in fact I would like in next six months to one year each college that you represent could have a small set of servers where you implement a mini or micro cloud and study all utilities on that micro cloud which are available in open source and use it extensively for your own activities thank you so much we'll now close this interaction thank you for your very positive feedback you have taken note of the points that you have raised first of all let me introduce professor Gayatunde I briefly mentioned that he has been working with us for a long time and more importantly he has been participating in all of our teacher training workshops in fact it was thanks to his initiative that a large number of other colleagues from mechanical engineering and other engineering departments started participating making this whole T10KT effort a very inclusive effort across the engineering departments and spectrum I'll now request professor Gayatunde to say a few words thank you professor Fatak as professor Fatak said I have been rather very willing guinea pig for his experiments particularly when they extend beyond his core competence of computer science and engineering and he knew this because we have been associated with each other since maybe 1985 or so when we really started working and both of us have a common reputation is that when asked to do something we will initially will not say no we will do it at least once very faithfully very sincerely and as properly as is possible within the given resources and time constraint second time when asked for we may say no saying I have done it once I have shown how it is to be done we will not do it again however when it came to the NMA ICT or Ecolovia project I have not said no to a second time I think professor Fatak is doing something third or fourth time because this has been a really enjoyable experience particularly because it was the empowerment of teachers that was the main objective and although the main objective was the empowerment of teachers the derived or derivative objectives are maybe better students come out hence better engineers come out and finally those students who graduate from better empowered teachers will be better engineers better postgraduate students and finally maybe the next generation of better faculty members in many engineering colleges so there is some sort of a loopy purpose here one of the comments which was made directly or indirectly during the interaction took me back to my thermodynamics courses there the complaint was in the feedback that sir we know now what thermodynamics is all about we understand it very well we know how to learn it and how to teach it very well but this doesn't really help in our students clearing the exams which they have to write for getting the degree from the university I think here we have to do a bit of re-meaning of the empowerment the teachers are empowered not only to do better teaching this teacher should also be empowered to put pressure on that subgroup of teachers who are members of boards of studies and various university committees see the university syllabus and the examination system is pretty old and by today's standard pretty old means maybe even 5 or 10 years old is not just out of fashion things are changing so much 10 years ago the power of ICT was not really appreciated today it is appreciated so use this empowerment to not only do good teaching but also to canvass and pressurize your colleagues who are on boards of studies and other university committees to get the syllabus and the examination system changed appropriately because it is only you can do it just by listening to these courses and studying some subjects in a modern way and a better way is not the end of it since it is expected that you will use this for betterment of your teaching learning processes and even educational administration I am told a survey is being planned and all of you will be partners in that survey not only the teachers who have registered for this particular course but even maybe about 1.5 lakh teachers so far who have registered 85000 teachers so far who have registered for some course or the other in this series of TKT and T10KT programs thank you thank you so much I really appreciate a large number of colleague teachers from various colleges who have participated in this workshop to make it successful I take this opportunity to thank all of them take this opportunity to thank all the remote center workshop coordinators and the RC coordinators and the technical staff there needless to add all of this will have been absolutely impossible unless our own teams working almost round the clock had made it possible to conduct this workshop in a seamless fashion so I would like to take this opportunity to thank my workshop team my video team and the other backend teams I am very sure that you will not let the momentum slip and you will complete the post workshop assignment which is supposed to be a team assignment kindly do as good a job as is possible please use this opportunity to learn something more about collaboration perhaps long distance perhaps through email but it's a very exciting experience and you'll all benefit from that thank you so much I declare the closure of this workshop now please do fill up the online survey and the other assignments in the afternoon thank you
