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 architecture and interfaces, Automated Intelligent Management (AIM), and Broadband Network Data Collection (BNDC).
Outcomes: WT-451a1 will go into Final Ballot and will be published soon.
The architecture of CloudCO (WT-384i2) was completely revised in order to expand the applicability, better define the responsibility of each component, and to extend the deployment of cloud-native network functions (CNFs) in CloudCO.
The Tiger Team on CloudCO interfaces (WT-454i2) agreed to sunset the old data models and move forward with new ones based on IETF recommendations.
The Tiger Team on Intent Based Interface (IBI) held calls with TM Forum (TMF) to understand how an intent-based interface should be defined (expectations, target, conditions). The next steps include holding a workshop with TMF and defining the use cases.
WT-413i2 on SDN Management and Control interfaces will incorporate a new section on BNG and DBNG. Regarding WT-414, it was agreed that the NPIF will be reviewed to define both interoperability and conformance tests for the interface between the SDN Controller and Access Node.
New pull requests have been opened for data models related to vDBA (WT-403a1) and to BGP and MPLS (WT-477i2). If the one related to vDBA is approved, WT-403a1 will move to Final Ballot.
Automated Intelligent Management (WT-436i2) and Data Collection (WT-508) will need further discussion and alignment to better define the integration in the CloudCO environment. More discussions are also needed to define the necessary protocols and definitions for data collection.
