ISE ICT SOLUTIONS EDUCATION 48 Group ISG we have seen the specifications in Release 2 and are heading to Release 3 At the same time proof of concept projects are evolving with a number of interoperability tests taking place across the globe Even so there is still more work to be done One of the key issues when dealing with next generation virtualized networks is the integration of the network functions and the network services created by composing them with independently developed management and orchestration systems In order to tackle the issue it is important to ensure an open ecosystem that will facilitate innovation from a range of new and existing players That is why during 2017 the NFV ISG introduced unified API specifications aiming to make multi vendor interoperability possible at the same time accelerating the roll out of NFV The idea is this will lead to interoperable solutions and network services from a variety of different vendors The API standard sits alongside the release of specifications covering the packaging structure for the distribution of virtualized network function VNF the definition of metrics for monitoring the supporting infrastructure the application of acceleration resource management and a complete revision of the use cases that were defined at the start of the NFV initiative In addition 18 new work items have been approved related to service provision security and privacy enhancements network slicing and new formats for describing functions and services The Next Steps Fuelled by innovation and the move towards 5G the momentum behind NFV standards and specifications is set to continue Over the next year work is being done on Release 3 which will provide specifications and advice for making NFV technologies fully operational Release 3 will also help improve and enrich the framework we have provided in the concrete specifications and make it easier for NFV deployment and operation globally As part of this we have started to examine how best to apply NFV to network slicing Meanwhile as cyberattacks become more complex and sophisticated there is also a focus on ensuring that solutions are secure by design Taking this into account NFV security is of paramount importance to the ISG and therefore will become even more significant in the coming year Another area of focus is automation which is of course a key part of NFV In this area we have to address the reduction of complexity analyzing how NFV DEPLOYMENTS ETSI
