 Question 14 is one of the questions of the slide 15, working party 3, responsible for the specification of a recommendation on management of transport network and systems and equipments. And transport technology we are covering or considering including our OTN optical transport network, carrier grade Ethernet, MPSTP, metro transport network and also synchronization and time distribution. And the specification cover from management requirement to the information exchanged between the transport entity and the system which manage or control these systems, these entities. And the information exchange across the system we are representing in two forms. One is neutral to the management protocol being used between these systems. And another form is neutral to whatever management control protocol being used between these entities. And the form in the protocol to neutral we call it unified and modeling language UML. And the form which is specific to the protocol such as the YEN, that's the one we use. And so besides this, we also specified the requirement for administering the management system such as SDN controller. So these are question 14 specifications enable the transport equipment vendor, the network operator and service provider to automate the management of the transport network and the supported services. One of the things that we do in question 14 is we do a lot of work with network management for transport equipment like Cam was saying. And so what we like to think of ourselves is being at the forefront of modeling technology. So we use several open source tools like Eclipse Papyrus for the UML information modeling. We use for repository management, we use Git for the management of Yang. We use P Yang and Yang Lint to support the validation of the instances of what we're trying to build. And this is very helpful to the industry because now we can start from the beginning where we describe the management space in protocol neutral way that Cam was saying about the creation of the management information. And then we capture that and then we have translation tools that take that and convert it into something that can be used with net comp Yang. We want to know that 5G will provide us very abundant viruses, various applications and those applications usually have different requirements on such as mobility and bandwidth delay and reliability, those aspects. And then it will require our transport network to meet those requirements to support 5G applications, especially if in management and control aspect that would be included rapid service opening and the dynamic resource adjustment and also maximizing the resource utilization, some those aspects. So for our transport management and control system we have to open the interface to the user to support the services and then the protocol neutral information model in our question 14 where become very essential because it provides the basic information that could be exposed to the user and also it could be exchanged by using different protocols as it needs. And then the other aspect is that for it also provided the data provision to the automation and intelligent obligations and that would be the premise of those obligations. Data is very important. And also for I want to mention that for the large scale networks usually we arrange the management and the control system in hierarchy and in this case is the standardized modeling where reduced the complexity between the different levels or systems that would be very helpful for. And so those aspects are very important for our transport network to support 5G so we encourage companies to join us and to contribute to the industry. Industry cooperation in standardization work is very key to the success of the standard. In the world of standardization there are also research groups and there are industry so it is very important for research to come up with ideas standardization to really concentrate on taking those ideas when they are ready to be standardized and then creating the recommendations that can be used by industry. The important point here is that it's a virtuous circle. It's a circle because when industry implements the standards there is no duplication of effort across the ecosystem. The industries nowadays are paying much attention to the natural automation. The premise is that the data is our question for the standards models can provide the or the specific data for the network operation and maintenance automation and some more intelligent applications. So that would be very helpful for companies to have a deeper understanding of those data if they come to attend our question 14 meetings and they will have much more chance to exchange the ideas with the other companies in the industry and that would be a very helpful for there to understand how to use those data. IDOT provide excellent environment facility and platform to support us question 14 to collaborate internally externally with the stakeholders. Internally I mean the sector members state members and the external stakeholder I mean the RSTO or forums through for example liaison communication things like that. So this is an excellent environment so we welcome people to join us to progress the standards work which will benefit everyone.
