Target: The SDN/NFV Work Area focuses on the introduction of Software Defined Networking (SDN) and Network Functions Virtualization (NFV) in conjunction with general purpose hardware to create the basis for cloud-based, edge, and access networks. Building on this framework, the Work Area addresses migration and coexistence of physical and virtual elements, into the broadband network, define interfaces, test cases, use cases and scenarios, reference implementations, and automation.
Progress: The main focus is CloudCO interfaces, disaggregated OLT, and Automated Intelligence Management (AIM) and Data Collection.
Outcomes: TR-386 Issue 2 ‘Fixed Access Network Sharing’ was published. Work was also completed on WT-403 Amendment 1 ‘PON Abstraction Interface for Time-Critical Applications’ by creating the data model and adding a new Annex A, and on WT-451a1 by revising Annex A, with both documents entering Straw Ballot.
A further revision was approved to restructure Chapter 5 of WT-384 Issue 2 ‘Cloud Central Office Reference Architectural Framework’ to improve the sections related to device disaggregation.
New call flows related to MPLS-LDP and BGP were approved to improve WT-477 “Cloud CO Enhancement - Access Node Functional Disaggregation”.
The Tiger Team on CloudCO interfaces (WT-411i2/WT-454i2) continues its activities on topology and network resource management for inventory by preparing a first draft of the WT-454i2 baseline text. Comments were received from Orange and TIM regarding the device hardware model for better deployability, which will be discussed further by the Tiger Team.
On the Artificial Intelligence and automation fronts, functional requirements were discussed for WT-508 ‘Broadband Network Data Collection’ (BNDC) and security aspects were analyzed for WT-436i2 ‘AIM Framework and Architecture.’
A new project on “Intent-based interface between Orchestrator and SDN Management and Control (Occo-Nf-sdn)” has been approved, with the first phase of the project to define the use cases for the intent-based interface.
