Network Slicing is used to unify and extend the concepts of optical network virtualization and (network) function virtualization. It has emerged as a key enabler for 5G deployment and dynamic networking and its applicability domains include intra-datacenter networks as well as the access, aggregation/metro and core network segments. In this context, the network and infrastructure is “sliced”, with end-users being provided an abstracted topology view of the physical, underlying network. The granularity level of control given to tenants depends on operators’ policy.
This panel aims at discussing these concepts from multiple perspectives, with emphasis on the optical domain:
i) Operators’ view of this trend, actual applicability to optical networks, associated challenges, use cases and business models;
ii) Requirements and network architectures enabling the virtualization and slicing, including dynamic management and orchestration of slices and their lifetime management;
iii) Industry status, testing and emerging standards. Ongoing and planned Deployments.
The take-away message is related to the role of the optical technology in network virtualization and network slicing, including to what extent next generation programmable hardware for optics should support some form of virtualization and its performance trade-off.
