Open vSwitch (OVS) is a multilayer open source virtual switch. OVS is designed to enable massive network automation through programmatic extension, while still supporting standard management interfaces. OVN is a new network virtualization project that brings virtual networking to the Open vSwitch user community. OVN includes logical switches and routers, security groups, and L2/L3/L4 ACLs, implemented on top of a tunnel-based overlay network.

In this presentation, we will provide an overview of the current state of the projects and their future plans, such as:

- The current state of the Linux, DPDK, and Hyper-V ports
- A status update on a portable BPF-based datapath
- The latest stateful and OpenFlow features available in OVS
- Performance and debugging enhancement to OVN
- OVN features under development such as ACL logging and encrypted tunnels

There’s a lot of buzz surrounding the potential for 5G to completely change the technology landscape and enable massive connectivity and IOT. But what is 5G really? What is the market opportunity for 5G and what infrastructure is needed to support it?

Currently Opendaylight sfc project use OVS and our NSH patches to implement NSH-based service function chaining, but we failed to push our NSH patches to ovs and Linux kernel because of various factors, but VPP is another high-performance data plane implementation, it has included NSH and Vxlan-gpe support in official release, so people can feel free to use it and mustn't worry if related code is in official releases or not. From 17.01 on, FD.io VPP project has supported IETF ACL and classifier, so we can use VPP to achieve high performance service function chaining without ovs involved, this provides another choice for users to deploy service function chaining solution. This presentation will demonstrate and showcase how we pull it off.
