- 6. fd.io Foundation Introducing VPP (the vector packet processor) Accelerating the dataplane since 2002 Fast, Scalable and Determinisic • 14+ Mpps per core • Tested to 1TB • Scalable FIB: supporting millions of entries • 0 packet drops, ~15µs latency Optimized • DPDK for fast I/O • ISA: SSE, AVX, AVX2, NEON .. • IPC: Batching, no mode switching, no context switches, non-blocking • Multi-core: Cache and memory efficient Network I/O Packet Processing: VPP Management Agent Netconf/Yang REST ... ethernet- input dpdk-input af-packet- input vhost-user- input mpls-inputlldp-input ...-no- checksum ip4-input ip6-inputarp-inputcdp-input l2-input ip4-lookup ip4-lookup- mulitcast ip4-rewrite- transit ip4-load- balance ip4- midchain mpls-policy- encap interface- output
- 7. fd.io Foundation Introducing VPP Extensible and Flexible modular design • Implement as a directed graph of nodes • Extensible with plugins, plugins are equal citizens. • Configurable via CP and CLI Developer friendly • Deep introspection with counters and tracing facilities. • Runtime counters with IPC and errors information. • Pipeline tracing facilities, life-of-a- packet. • Developed using standard toolchains.

- 9. What is in the VPP Package?What is in the VPP Package? ● SRPM ● Generates total of 5 RPMs ● Includes embedded tarball for DPDK ● Generates Static Library ● Other Plugins and APIs ● Dynamic Libraries ● VPP Library ● VPP Daemon ● Other Utilities ● Configuration Files
- 10. Community HealthCommunity Health ● Meetings on IRC BiWeekly – https://wiki.centos.org/SpecialInterestGroup/NFV ● Healthy and Active but ● Minimal Community Participation ● Although there has been some nibbles, there is no sustained interest in new packages. ● No new active committers. ● Little or no Participation in Meetings ● Strong Interest in the VPP Packages ● VPP, OpenvSwitch ● DPDK, ODP etc.
- 11. NFV SIG Current StatusNFV SIG Current Status ● Packaging for fd.io Project ● VPP Package ● Release 1807 Available ● WIP: 19.01 Release ● Prerequisites for VPP 19.01 ● Open Daylight SDN Controller – Not in repo but built in Project CI
- 12. NFV SIG FutureNFV SIG Future ● Ideas to Broaden the Community? ● Warning Provocative Question – ● With containers and Kubernetes, are we obsolete? ● What does the community want? ● More ackages for NFV ● Dataplanes such as ODP? ● Aarch64 Support? ● VPP is a plugin architecture ● Separate dpdk package? ● Kubernetes on Centos? ● NFV for Containers
