2. Open-O NFV-O Project Proposal Version 2.0 Draft – For Review Lingli Deng denglingli@chinamobile.com

3. Overview Project Name: NFV-O Repository name: NFV-O Project Description This project is using ETSI NFV MANO architecture and information model as a reference, and targeted at implementing the NFV-O Component that provides orchestration for Network Services composed of Virtualized Network Functions, as an integral part of Open-O. Project Participants China Mobile, Cloudbase Solutions, Huawei, Intel, (RedHat), ZTE

4. Problem being Solved Service Agility has been the major promise of SDN/NFV to service providers in transforming their legacy infrastructure into the virtualization paradigm. Automation of service delivery via NFV orchestration is at the heart of realizing service agility, which significantly reduces time to market for new service offerings and reduces CAPEX/OPEX. This project is targeted at implementing the NFV-O Component that provides orchestration for Network Services composed of Virtualized Network Functions, as an integral part of Open-O. This project is also targeted at implementing plugins/drivers to enable support for multiple VIM, VNFM or SDNC from different vendors.

5. Project Scope (1/2) Problems being Solved by NFV-O Release 1 Realizing basic LCM and resource orchestration for network services Providing the integration specifications for VNFMs/VIMs/SDNCs NFV-O Release 1 Features and Functionality: Basic LCM/SO of NSs Life Cycle Management Features Basic NS LCM operations in scope include: NS template design, NS package onboarding, NS instance creation, NS instance termination and NS package deletion. (Note VNF package onboarding might be originated by NFV-O or VNFM.) Sophisticated LCM operations, e.g. NS instance healing and NS instance scaling, are currently out of scope. NS in scope are composed of VNFs and the connections to be deployed within a single VIM. NS orchestration composed of VNFs residing in different VIMs are currently out of scope. GUI portal is provided for both NS template design (including workflow editing) and LCM operations. Basic monitoring of fault alarms and performance stats for VMs and Hosts Collection/Monitoring of stats for the VNFs are currently out of scope Resource Orchestration Features Resource authorization for LCM operations originating from VNFMs Sophisticated features, e.g. Intelligent allocation based on affinity, are currently out of scope

6. Project Scope (2/2) NFV-O Release 1 APIs/interfaces NBI: Interfaces between GS-O and NFV-O based on REST API; SBI: Interfaces between NFV-O and drivers for (VNFM, SDNC, and VIM) on REST API; VNFMs in scope: g-VNFM (JUJU), s-VNFM (Huawei), s-VNFM (ZTE) VIM in scope: OpenStack XXX (RedHat) SDNC in scope: ODL (SFC) Information Model and Data Models Candidates under consideration: ETSI NFV 1.0/2.0, TOSCA NFV Profile v004/005, YANG for SFC To be aligned with O-Common and GS-O

7. Testing and Integration Plans NFV-O Integration Test Strategy (update) External and internal interfaces are to be agreed first Inner interfaces/workflows between sub-modules within NFV-O NBI of NFV-O between GS-O SBI of NFV-O for VNFMs, VIMs and SDNCs Each sub-team for individual sub-modules are responsible for unit testing separately NFV-O splits into micro-services with well defined and agreed REST APIs A testing group will be established to coordinate integration testing of NFV-O Integration into OPEN-O Test Strategy Have a representative to join the testing project as a committer and make sure the testing of NFV- 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 NFV-O and other components of OPEN-O will be shared/agreed/reviewed by other projects and follow the guidance of the TSC/Architecture committee. NFV-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.
