Understanding OPNFV 75 Projects aimed at easing the integration of various upstream projects into OPNFV include: Project Description Forwarding Graph (OpenStack based VNF forwarding graph) This project plans to work with OpenStack networking-sfc and Tacker, along with ONF OpenFlow to demonstrate that this combination of technologies can be used to dynamically set up VNF forwarding graphs (VNFFG), aka service function chaining. It further demonstrates that traffic from different tenants can flow through distinct service chains (that is, a sequence of VNFs). Movie (Model oriented virtualized interface) OpenStack has an IaaS-centric API. However, that burdens the MANO layer with a lot of detailed work. The Movie project is creating a more abstract VIM northbound API (NBI) as an alternative to the existing OpenStack API, which could simplify MANO's job in areas such as resource access, connection generation, flow identification, policy operation and so on. NetReady (Network readiness) Given that NFV is first and foremost a network-centric workload, the NetReady project performs the important role of understanding the gaps in current OpenStack networking models and APIs, as they pertain to carrier grade needs. Requirements such as L3 only, WAN connectivity, and support for legacy networks, and so on for specific NFV use cases means that the current OpenStack networking architecture needs to be evolved. In addition to OpenStack Neutron, NetReady works with the new OpenStack Gluon (Model-Driven, Extensible Framework for NFV Networking Service) project. NFV-KVM The NFV-KVM project focuses on the KVM hypervisor in the NFVI and develops requirements and collaborates with the upstream community to achieve this integration. By using real- time KVM, the community has shown a 10x improvement in small packet performance. ONOSFW (ONOS framework) The ONOSFW project develops requirements for the ONOS SDN controller in OPNFV.
