Towards Virtualised Networks
Network virtualisation leading to cloud like networks (NaaS) has been subject of active research under FP7 and is now becoming an area of interest from a deployment and standardisation perspective. Network Function Virtualisation is expected to bring multiple benefits from a network operation perspective, also in conjunction with the emergence of Software Defined Networking. The panel will review established and emerging trends of network virtualisation, assess the benefits, enablers, and challenges of network virtualisation and outline the complementarity with SDN especially in the context of transport network deployment & management. From that perspective, the panel is expected to address critical research challenges and debate the main elements of an industrial research roadmap in the field.
Questions that will be discussed include:
- What is the current status of deployment of network virtualisation? What are the benefits already achieved and expected?
- What are the key enablers (technology, market, regulation, standards..) towards fully virtualised networks?
- What are the main remaining challenges and what the industrial innovation roadmap should be considered?
- For which network domains and layers, network functions virtualisation makes a realistic proposition?
- What is the complementarity between network virtualisation and SDN based operations?
- How can SDN with virtualised networks lead to optimised network operations?
- Does transport SDN makes sense? How from traditionally controlled/managed transport networks evolve to SDN service orchestration architectures?
- How will network operators and equipment vendors adapt to hardware commoditisation supported by SDN based architectures?
- Could large scale European testbeds be of relevance to accelerate development and deployment?
