 Okay, so it's about 11.15. So we'll go ahead and get started Want to welcome everyone to this session. Thanks for making the trek over from the main hall We're hoping that it wouldn't deter participation. So we're glad to see all of you. My name is Anise shake. I'm with IBM I'm joined up here. This talk is going to be a bit of a tag team We have a few representatives from you know different organizations that are participating in the open daylight project So with me Stefan Balka from Ericsson Kyle Mestri from Cisco and Chris Wright from Red Hat So what we want to do in this session is actually we have some charts that we'll go through But we want to do that relatively quickly, you know in about half the time if we can and then really leave the rest of the time For you to ask questions about the project clarifications You know any information that you'd like and we'll answer as many questions as we can or we'll get you the answers Afterward if we can't but I think my colleagues will do a better job than me So in this talk, we're gonna cover a few things, you know, not everybody may know what open daylight is all about You may have heard about it read about it So we're gonna give some background, you know, what is open daylight? What is the project about? You know, who are the participants, you know, who makes up the community in open daylight today? Our first release is code named hydrogen So we'll talk a little bit about what's in hydrogen what you can expect to see When the first release comes out at the end of this year And then the focus of the latter part of the talk will really be about how open daylight Integrates with open stack and we really want to position open daylight as you know, the de facto standard SDN Platform to support open stack deployments and so we'll end with that and then we'll have time plenty of time Hopefully for questions and answers So first I'll start with what open daylight is so it's an open-source software project. It's not a standards project or standards body we are Organized under the Linux foundation. It's not a Linux related project as such But we are in under the umbrella of Linux foundation Linux foundation provides us with a lot of support both infrastructure organizational You know outreach and publicity So they've been a fantastic partner for the project and the goal of open daylight is really to drive the adoption In the marketplace and among users for software-defined networking technology. So through having a sort of common industry accepted Platform that a lot of the community and the industry has come around to create We hope to really drive adoption much more rapidly for SDN So there's sort of three main sub goals here one is of course code. It's an open-source project after all and so our main Product is code and we're really focusing on creating a robust and highly extensible code base that covers all of the major components you need to set up an SDN environment and We judge our success in a number of ways But one of the ways is around acceptance of the project so broad industry acceptance both among users and vendors So on the user side, you know, obviously we want users, you know, using open daylight to address their networking problems You know using the SDN capability that it provides, you know Either themselves directly by you know, using the community open-source version or through a vendor package version and then among vendors You know, we like to see vendors Introducing products into the market that are based on on open-day line And of course, you know the third and maybe most important aspect is the community to really have a thriving and growing technical community. We're really pleased with the amount of interest that's been shown in open daylight thus far We have lots of participants across lots of organizations, you know big and small Individual and affiliated So Chris is going to talk more about that in a couple of slides So what are we building? What is the main product going to be? So the focus is really on building an SDN platform So it's not a whole end-to-end solution But it's a highly modular platform that can handle a diverse set of use cases and multiple implementation approaches There's lots of innovation happening in the in the SDN area right now we really want to embrace and Encourage that in the project In addition, there's a set of common abstractions that we're building into the platform that basically abstract these capabilities that are in the platform For an application user through a set of northbound application programming interfaces API's and then we have a layer that does translation or intermediation of those capabilities Into protocols on the so-called southbound side of the controller when we show the architecture It will become a bit clearer. There's a set of core network services that every SDN platform needs You know things like topology discovery Tracking, you know where switches or network devices are where hosts are et cetera there's a number of core network services that are programmable and reusable in the platform and It also includes a set of network applications So some of the projects in open daylight are focused on building Applications that run above the controller whereas others are focused on building new services that reside in the controller And then of course is a number of additional things that we need to make all of this come together You know, maybe most importantly integration and testing and there's a lot of focus on that We have a separate project just focused on testing. So as I said, we're gonna tag team I'm gonna turn it over to Chris to continue and then we'll move on down All right. Thank you So digging a little deeper or giving a kind of graphical view of that architecture that Anise was talking about This is open daylight. This is the architectural view of open daylight If you look at the top of the picture, this is where the applications sit so this would be above the northbound APIs the northbound APIs are a Fairly critical part of this project It's again, not a standards organization the open daylight project But we're trying to build the de facto standardization of APIs in an SDN environment so that application developers have a Single reference point for building their applications and don't need to make Difficult choices about which arbitrary commercial controller are we working against instead we can build against a common set of APIs those APIs are built on top of this the services that Anise was referring to and in the middle of all of this is something that we call the service abstraction layer It's a fairly key part of the project the service abstraction layer is the piece that allows us to Decouple those northbound APIs and services from the southbound technology that's talking to each of the different forwarding elements You know most people in the SDN space are very familiar with open flow open flow is a perfect example of a southbound Plug-in and a protocol that you would speak from the controller down to the forwarding devices, but Our view within the project is that open flow is just one implementation of that kind of control plane And there will be others and we want to make sure that that abstraction layer is the piece that allows Applications to continue working regardless of the communication path between the controller or the protocol between the controller and the forwarding elements If you see on the far right of this slide, you notice that there's a curly bracket that's identifying open daylight The purpose is to say that's the scope of the project. It's a fairly wide scope. It's inclusive of the southbound plugins It's inclusive of that central service abstraction layer. It's inclusive of the Northside services and the API is associated with them and applications as well Down in the very bottom. We have some some actual forwarding elements Those are are sort of nominally placed out of scope because it's you know It's a whole different world of building either hardware or virtual switches that those those solutions already exist and we're not trying to reinvent that So we'll look a little bit at One view of who open daylight is open daylight is sort of an industry consortium our goal is to promote an open source community around building an SDN controller and This is the corporate sponsorship that's building that community. So if you saw Mark McLaughlin's keynote this morning He stressed that in on the one side. We have corporate interests and on the other side We have community members and that these are not sort of mutually exclusive groups and in fact many of us are employed full-time by these Sponsors to help us build this infrastructure and this technology So it's an important view of who's involved in the project if you look at the list you see a lot of familiar names for the networking space and You know, I like to refer to it as a veritable who's who of the networking industry And that's exactly the kind of momentum and community that we're trying to build in the open daylight project If we look one level deeper at who's actually involved, it's a community. This is a community based on openness Concurrency transparency anything you would expect for building and maintaining a community open-source project currently there's on the order of a hundred different contributors and we are Seen an increasing number of projects coming into the umbrella project. So we started off a little over six months ago Actually, maybe almost exactly seven months ago at this point We started off initially with two projects. We're up to the order of about 15 projects in that short time period and We'll go through some a review of some of those projects and some of those that will be released in the upcoming release and hydrogen in early December And again, I think Anise mentioned a strong integration and testing community That's something that should resonate well here the open-stack design summit It's the integration and testing in the open-stack context is one of the key pieces that's allowed open-stack to Move so rapidly and innovate so quickly and we we believe very strongly that that's a critical part of building the infrastructure for building this project So that's actually a plea to anybody out there who's interested in integration testing. We could use your help This is just a quick view and then I'll turn it over to Stefan to talk about the actual details of the release, but as I mentioned it we are Upwards of 15 projects at this point the the nomenclature their bootstrap or incubation refers to the beginning stages of our Process for bringing projects into the umbrella project The again the codename for this first release is hydrogen. It's come it's due out December 9th and We have a notion of additions or delivery vehicles or mechanisms for for giving this Bundle of software to users and we're bundling this software in a number of different ways one is of what we call the base edition and this is of Intended to be just the simplest bare bones pieces of functionality you need to to run the controller there's a virtualization or kind of cloud-centric Edition and that's something that's that we'll talk about With with Kyle's review of how we're integrating with OpenStack And then there's a service provider addition that's geared more towards providing the SDN level requirements that you would see in a service provider environment I Think that's it. So what I will turn it over to Stefan to talk about the Details of the simultaneous release coming up. Thank you. All right. Thank you Chris So here you see on the list of the project that we currently have as you can see It's already a pretty considerable number and this is mostly thanks to the highly modular nature of open data It's designed, you know to accommodate easy addition of new projects as we go along and we have 15 at the moment But we expect more to be added soon So since there's no time to go through all of those in detail right now I will just very quickly say a few words about each of them and if you have more detailed questions Please do this in the Q&A session afterwards So I would start with a controller which is really more like a controller platform which You know provides the base OS GI Java framework that we use You know To support the modular design of the platform It also includes what is called the service abstraction layer Which is an abstraction layer that allows us to support a multitude of southbound protocols using plugins It also has to the northbound towards the consumer like opens like for example a framework for northbound API It's an extensive extensible API framework that supports both local APIs using OS GI but also web service RESTful APIs for remote consumers So this is really you know the central piece of it, but it allows Allows us to host, you know a multitude of service and that's basically what the other projects are currently doing we have Two services right now that are focusing on network virtualization, which is really what is Probably very relevant for open stack going forward. We have VTN virtual tenor networks, which is a SDN base an SDN but network virtualization controller based on open flow It provides a logical network abstraction that is reminiscent of of you know the traditional networking view a two and a three Logical network elements that that we are used to that's what it exports to the northbound And it also has an interesting You know application on top, which is called the VTN coordinator Which allows us to provision networks across multiple open-data controller when it's when it's finalized The next project open-dav is a network virtualization solution that is based on Overlay networks on top of IP it uses VX LAN and capsulation, but it has its own control plane So it does not rely on on IP multicast for example for broadcast replication It has its own control plane and to the northbound it will Expose an API that is geared to be neutron friendly. It's basically designed to be easily You know integrated with with open stack We will talk a little bit about that in in kiles section later on the next service affinity management service is essentially a Language that allows applications to express their needs towards the network like for example you can specify quality of service policies between the components of an application group and That allows the SCN controller essentially to configure the network according to the needs of the application without You know requiring the application to be aware of network topology and specific details of the underlying network Lisp mapping service lisp is as most of you probably know, it's an ITF standard for location identity split it can be used you know to build to do network virtualization based on a separation of logical and physical planes and What this this list service in open daylight includes is a mapping service that? provides information and access to the open daylight services to the mapping between physical and logical resources and It also includes a southbound lisp plug-in That allows open daylight to you know configure lisp aware devices in the network So this could potentially also be used as a network virtualization service to support a neutron at some point The next Project yang tools is about it's basically about building a tool chain for yang Which is the modeling language that was chosen by open daylight? to you know express models for the various southbound protocols and southbound technologies that we support and They built or they are focused on building tools to support the infrastructure of open daylight Finally defense for all is one of our first Applications I would almost say it's you know utilizing Open daylight to provide detection and mitigation of distributed denial of service attacks Imagine you know using an SCN controller to to place probes in the network or to to redirect traffic that is suspected You know to be malicious into a scrubbing service before it reaches its target, right? So so you utilize a programmability of the SCN based network to do effective defense against now of service attacks finally the the the group of the last four projects listed here is Implementing a number of southbound Plugins to support a wide variety of protocols one of the goals of open daylight is to support a number a Spectrum of deployment scenarios and very different that that on very different network technologies with different protocols And here you see a few of the projects that are adding Support for more protocols beyond just open-flow and that comes what what is currently being supported. So bgp ls is is a bgp-based protocol basically to Distribute information about topology and traffic engineering from the network to the SCN controller and the SCN controller can use that information to make smart decisions about configuring the network and for that it can use PSAP Which is a protocol for that was originally developed for path computation engines But it allows the open the open daylight controller to for example configure paths in in your network using for example MPL STP sorry Open-flow protocol of course is well known Open-flow 1.0 is supported as part of the base controller platform But we are also working on extending that support right now We are planning for the first release to have support for open-flow 1.3 And the way this works is we have a Java implementation in the form of an open-flow library and based on that Open-flow southbound plugins can be implemented rather easily. So we plan to support to support 1.0 1.3, but also upcoming future Open-flow versions OVSTB is a southbound plugin to support open v-switch OVSTB protocol obviously to to be able to configure open v-switch and This is also currently being used to implement or it's it's an upcoming use to implement neutron support using OVSTB and Finally, we have another southbound protocol support SNMP for SDN Which honestly, I don't know all the details about but it is a very interesting approach of using SNMP to to configure Flows in Ethernet switches from what I understand But it's also planned to extend this to further use this or to use SNMP for for a wider variety of things later on So let me just give you a brief Overview look of what the whole thing now looks like The basic structure was already described before as you can see this this is quite a big number of of components that we are dealing with and you know adopting this for deployment Can be a daunting task. So what? Open data decided is that that we are going to prepackage a number of editions as already mentioned by Chris We have the base edition, which is basically just the SCN controller. It can be used for testing experimental purposes, for example Then we have a service provider edition, which is Targeted at the needs of network providers and finally and most interestingly probably for from the open stack perspective Is the virtualization edition which is geared towards data center networking essentially so it is it basically contains the subset of Open data components that that are most likely to be needed for this particular purpose like in this case the Network virtualization services and the open stack adaptation service that Kyle will talk about in the next few slides Yeah, and with this I think I will hand over to Kyle now We'll talk about opening second duration So so hopefully that was a pretty good background on everything as far as what open daylight is what it's made up of So now at this point I'll kind of go through the integration. We have planned for open stack neutron as well And so what you can see in this slide here is is a rough diagram of how this is going to work So the open daylight team has actually taken the time to come up with This open daylight I think it's called the neutron API service effectively and those are the northbound APIs on open daylight there And those are the APIs that that map to the neutron APIs at this point and effectively allows our open stack neutron plug-in to communicate with open daylight the idea here is is that effectively The neutron plug-in can be a thin proxy that that sends all the requests down to open daylight and open daylight can then handle Orchestrating the virtual networks the physical networks, whatever you need This also allows multiple implementations To be plugged in to the open daylight API service inside of open daylight there as well There's a lot of benefits to this design not the least of which is it simplifies the the open stack neutron plug-in That that's that's actually a huge benefit by keeping that thin And moving all of the the orchestration of the networks and everything like that into open daylight as well at this point effectively it pushes all of the the complexity of this down into open daylight and kind of removes it from open stack neutron as well we You know we'd we'd like this to be the effectively the the open source controller implementation for for open stack neutron In other words, this would be the reference implementation of if you're going to use an open source Controller with open stack neutron, you know, we'd like this to be the reference one effectively So this this work is is currently ongoing right now It's like I think the the other guys said it's planned for the hydrogen release at this point The open stack neutron API service is now available. It's it's been available for I Think it's been at least a month now in the open daylight project as well So we're we're actually actively involved with writing the plug-in on the neutron side to utilize that on The flip side inside of open daylight itself A lot of the other projects that were mentioned like OBS DB Open Dove VTN they're in the process of integrating with that API on the southbound side of it So that they can be enabled by the open stack neutron plug-in as well You know the initial work is is focused on I guess at this point a modular layer to plug-in for neutron as well We're going to enable additional Services as well as we planned it The the plug-in is is planned to be upstream during the ice house release of open stack at this point We have a blueprint filed The work has already started at this point One other thing that that I'd like to point out is we we have a github repository for all this work But the real interesting thing I think for the people in this room that maybe aren't familiar with open daylight But are familiar with open stack and specifically dev stack. We actually have integration with dev stack such that You can actually pull the github version of our dev of our dev stack and set up in your local RC And it will actually clone open daylight from get and it will start it in a separate screen window And set up neutron to talk to it as well So I think that removes some of the initial complexity from people that aren't familiar with open daylight You can just run dev stack and it will enable open daylight pull it down and then you can you can utilize it that way The dev stack integration also allows you to to use an existing open daylight install if you have that as well But I think that's that's actually a key thing and that and the plan is to push the dev stack work upstream as well I think that's that's actually really nice for people that they want to just give it a give open daylight a spin with open stack neutron So I think we're almost done with the slides here. This is the the call to action slide So open daylight is open to everyone. We'd love to see more people participating in the project Whether it's you know documentation Qa development however you'd like Like any great open source project. We have all of the standard things mailing lists and IRC channel Bring your patches if you find a if you find a bug or you'd like to implement a feature, you know We'd love to have you involved with that bring your project proposals Go ahead and try out the new the neutron integration or just download it yourself and and run open daylight and give it a give it a try I think this is our our final slide You know we have a wiki as well We also have weekly open conference calls that are open to everybody if you're interested in open daylight Those are actually a great way to to get a feel for the project to join the the weekly conference calls as well We have an IRC channel like I mentioned before mailing lists as well a Twitter account and a hashtag so So there we go So I think it at this point We're done with the slides at this point. We'd like to kind of make it an open Q&A from the audience so Yeah, I think the We have a microphone as well here. Thank you So does anyone have a question? Yes? Thanks for the all the detail information about that actually we are really interested in this kind of seems like a really true truly open kind of Hopefully SDN approach in OpenStack in general actually the Lot of actual concern in terms of using SDN technology, but I would say let's say to be concerned one is a kind of security issue and the other is a single point of failure of SDN controller, so Basically, I have two questions like how you know What kind of plan you have in terms of the limited security issue and as well as You know this bottleneck of or single point of a controller issue So the two questions one was how do we manage? Performance bottlenecks associated with being in the path potentially being in the path of packet flows and the other question is how do we manage this? centralized controller a Fault in that centralized controller killing your entire network so Initially Sesty n controllers can fall into two or three categories Typically called reactive proactive and hybrid Our you know, I think at least my view we're working at Red Hat and working within a cloud infrastructure We have an orchestration system OpenStack that knows ahead of time where it's placing all of the virtual machines So we can pre-populate all of the relevant flow table entries associated with The virtual machine traffic so that we don't need to rely on pushing every first packet or every unknown packet That's in the system through this centralized Controller in creating a performance bottleneck We're also simultaneously working on improving the what we call the packet in processing rate for the controller so we want to ensure that it can handle a large number of incoming packets that are Need to be inspected and reviewed by the controller and then it reacted in reaction to some, you know unknown event that we need to handle from on the controller side the Controller it's usually referred to as a logically centralized controller. So it's a distributed application So this is not a single point of failure. It's a cluster We use clustering technology to replicate the data across all the controllers And it's actually an interesting space for innovation in in this project Currently we're using in memory replication of all the state using the project is a Java project And we're using the Java building block called in finis band to do the replication We're also looking at adopting other techniques and some of the projects and within the open daylight controller like the Lisp mapping service use Cassandra for state replication and Distributed storage. So, you know, there's a lot of room for Innovation there and and pushing the envelope, but fundamentally it's a distributed application So it's not a single point of failure and in a cloud context It makes most sense to do mostly proactive flow and a flow setup Just to your question about security I think also right so You know, we we have multiple southbound plugins as As we described in the architecture and you know, we have this notion at least for the open flow part of the controller This notion of a connection manager where not yet, but it's actually work That's ongoing to you know, secure the connections to the switches for example introduce You know TLS and secure connections down to data plane devices as well as For the northbound side to secure, you know, API calls Into the controller. So the controller does have a notion of, you know Roles as well and you can use roles and another notion called containers They can also be used to isolate function and make it available only to you know, authorized users So there is definitely work ongoing on the security side I won't say that we have all of it figured out yet, but at least in the context of the open flow controller role There is a fair bit of work ongoing And you know as Chris described the single point of failure mitigation through clustering Yeah, go ahead the scale target Yeah, that's a tough one it's kind of an ongoing You know, it's work in progress on scaling, you know I think the controller has been tested with you know up to you know 50 instances of it so that you could scale it out the scale the cluster of the controller 40 or 50 I can't remember what mother said, but it's a pretty big number But the default is kind of you know like four or five instances for a data center is kind of how you would imagine running it as far as you know Packet in rates for the open flow piece, you know some of the comments that Chris made about performance are kind of specific to the open Flow operation. There's other things that we do other than open flow in the controller But you know through a bunch of performance work. We've Right now. I think we scale up to 100k packet in this per second if you look at C bench type numbers Number of switches that can be managed that one I'm not sure but that's something that's sort of ongoing as another scalability targets to increase You know the total number of devices under management, but I don't think we have a number yet for that so, you know the scaling and performance work is kind of ongoing like perpetual right so You know we started with a certain scale and performance level I think over the last couple months. We've actually increased it a lot through changes to the threading model Changes to the IO libraries that we're using to make them asynchronous, you know moving some synchronous calls They being asynchronous to get to those higher numbers That we're aiming for but where's that's all work that's still ongoing So I'm sorry. I'm kind of hand waving a bit, but it's just because some of those numbers are still, you know being worked on directly Just want to mention that Even though we don't have hard numbers right now We are in the process of setting up a test bed that will allow us to do a larger scale testing And we should be able to provide you with some first numbers in a couple of months, I guess Yes, my question is that as you alluded the open daylight project is continued to evolve and now is the kind of an early stage of the development So what kind of propositions and values that you can see it could bring to the table and is in the first field releases Because like today I read an article from like reading some of the mobile carriers coming that like the SDN is not about capex Saving but probably are the features that it could bring to the table But someone I have your thought on you know what open daylight will bring to the table and this in the first few releases I ask you specifically for carriers at service wider. Yeah, so right? So I'll I'll ask maybe Stefan to take a stab at that since he's he works for a Okay, so I mean The service provider addition right that we're working on I'll just mention that kind of the focus areas of it, right? So, you know and in addition there's work that service providers are bringing and driving in SDN standards bodies like ONF Right open networking foundation that's driving the open flow standard and extending the open flow to be You know something that can be used in wide area networks and optical transport networks You know things that are more geared for service provider environments rather than data center And that work is also intended to be brought and implemented and reflected in in open daylight So today the service provider addition has functions for service writers that focus more on traffic engineering capabilities, right? So as Stefan mentioned, you know, BGP LS to get topology from BGP enabled networks PCEP to do path computation and pushing down, you know the results of those computations but in the future, you know as for example open flow evolves to address service provider Network problems in the ONF we fully expect that stuff to come back into open daylight and be, you know Available as reference implementations in the open daylight controller as well One other thing to consider the service provider space There's a lot of buzz around network function virtualization The open daylight controller has in already in it in this first upcoming release the functional capability of doing Service chaining and providing flow direction through network functions So that's a pretty meaningful impact to the existing service provider or one set of service provider requirements Obviously as we've mentioned a few times our goal is to grow this project to fit a wider and wider set of use cases so, you know come come with your use cases and patches accepted and We'll we'll grow the community together Yeah, I mean I would just add that, you know It looks like the technology may be kind of a data center focus and since we have service provider technology But you know we fully intend to have the platform address a wide variety of SDN Usage models, you know in service provider networks in data center networks in mobile and enterprise networks as well There's a question in the back. Yeah Hi, I've got a dumb question currently. I use open v-switch with Quantum in production How is my life going to change with open daylight moving forward? I you know if you could just give me a conceptual picture of what's going to happen and say ice house of moving forward So so are you you're using the open v-switch plug-in or as well or okay, so so effectively as was stated before For your type of scenario open daylight is going to have both open, you know open flow support as well as OBS DB support as well so the intention would be to To take your use case you could use the open daylight neutron plug-in and Effectively all of the the neutron API calls for creating things like networks ports subnets and things like that will be handled By both a combination of the open flow and the OBS DB code Inside of open daylight. So so we'll be able to both, you know, create ports on the host as well as well as set up flows To do things pretty similar to what your open v-switch plug-in is doing for you today at this point as well You know, we hope that the scalability would be a little bit better because I think the the open v-switch plug-in I I'm not sure how large of a scale you're talking, but I I know the open v-switch plug-in is Has some scalability challenges. I think at this point So so hopefully this should address some of that as well and also fulfill the use case you're you have right now when we're talking about open stack and neutron integration There has to be a way to specify what the networking requirements of the VMs are and I assume that happens through heat Can you talk a little bit about that and are there extensions needed to heat what's available today? Say a few words about that well, so first of all heat's not required heat is a Helper so it gives you a template language to do orchestrated application launching You could do it all manually There's a lot of steps to launch a VM and attach it to a network Especially if it's a collection of VMs and it's an application. It's a multi-tiered application Most of that functionality is already there in heat Open daylight is pretty far away from that. That's very Central to the neutron APIs that are available for managing your network resource requirements and The Nova APIs for launching virtual machines and associating them with these neutron resources there are a few Resource types in heat that are not available right now that would probably improve cloud formation Parity so that would be things that look more like an Amazon VPC style network But from a from an open daylight point of view We would see those as these fairly straightforward network topology requests that aren't They they're not going to fundamentally change how we're integrating with with neutron Hope I think hopefully that answers your question that helps. Thanks. I would just add that you know What we're focused on the initial integration as you saw is you know implementing the core neutron APIs as a as a first step, right? So those Neutron resources are already you know handled in heat as Chris was saying so from the point of view of extensions to heat You know at least initially we're just focusing on providing an implementation for neutron APIs core APIs And some of the extensions in some cases and some of the implementations Directly so it shouldn't require any changes yet The as neutron evolves and as open daylight support for different models and neutron evolve then you know heat would have to evolve Accordingly right? Yeah, so I guess this is going to be the last question since we have to wrap Just a quick question. I mean Given that we have a lot of like high-order network service types in neutron like low balancing firewalling I mean, how do you actually see that like? Working with ODL because if I understand correctly ODL doesn't actually do like firewalling as a service or or high-order application Based they're low balancing as a server. So how do you actually see that working with neutron? Yeah, I mean you're correct that currently we have no projects Like this in open data, but we're there's absolute interest in open data to address for two l seven services of that kind and You know the way This will interact with neutron is still very much an open question that that will depend on how the You know the insertion framework for example in in neutron develops over a long time But definitely this is in scope for for the open data project to develop this kind of service We just have no project at this at this point, but we expect several of these projects to be created very soon So and I just like to add one one quick thing as well So all of what you're talking about in neutron is effectively implemented now is like a service plug-in in there So there's really and they all have an open source implementation on the neutron side So in the short term those implementations for those service plugins could be used with the with the open daylight Plug-in as well So for instance, it's I'm not saying you could but for instance the routing is done using Linux network namespaces So you could utilize that I think HA proxy is done for the load balancer work So you could use that as well. So in the short term the integration would likely look like that Yeah, so I think we're out of time Just wanted to thank everyone again for coming. Please, you know find any of us We there's a booth for open daylight on the expo floor that Phil Robb is Manning so feel free to drop by please ask more questions and as Kyle showed you we're definitely looking for more participation from organizations individuals the project is open and Open to all of you to come participate. Thanks again
