Open-O SFC.Mgr Proposal Version 0.9 YiLiang Liu liu.yiliang@zte.com.cn

Problems need to Solved In the current OPENO architecture, SDNO and NFVO deployed their service function chain in different API & Model. In such case we can deploy service on hybrid network with both VNF and PNF. A universal SFC Interface can reduce running cost for operator. With a single model design system, service deployment time is halved, since there are overlap functions such as monitoring, elastic-scaling, self-healing for both VNF and PNF Improve extensibility for supporting multiple SDNC from different vendors. Just need to have one driver adapted with controller.

Project Proposed Project Name: SFC Repository name: SFC Project Description This project is using ETSI MANO architecture and service model as a reference. SFC Component will provides orchestration for Network Services Function Chain, as an integral part of Open-O. Potential Project Participants China Mobile, Cloudbase Solutions, Huawei, Intel, (RedHat), ZTE

Testing and Integration Plans SFC-O Integration Test Strategy (update) External and internal interfaces are to be agreed first Inner interfaces/workflows between sub-modules within SFC-O NBI of SFC-Obetween GS-O SBI of SFC-O for SDNCs and SDNC Drivers Each sub-team for individual sub-modules are responsible for unit testing separately SFC-O splits into micro-services with well defined and agreed REST APIs A testing group will be established to coordinate integration testing of SFC-O Integration into OPEN-O Test Strategy Have a representative to join the testing project as a committer and make sure the testing of SFC- O integrated into OPEN-O will be delivered based on OPEN-O Test Strategy defined by the OPEN-O Test Team Discussion on specification and testing of External interfaces between SFC-O and other components of OPEN-O will be shared/agreed/reviewed by other projects and follow the guidance of the TSC/Architecture committee. SFC-O Integration test plan and tests cases will be based on OPEN-O use cases and shared/agreed/reviewed by other projects and follow the guidance of OPEN-O Test Team.
