2. Agenda Problem statements and Opportunities
Introducing Service Function Chaining (SFC)
SFC Vector Packet Processing (VPP) Renderer and Classifier in Opendaylight* (ODL) SFC Architecture
ODL SFC and VPP Integration Architecture
ODL SFC and VPP Integration Demo Configuration
VPP Network Service Header (NSH) Proxy
Key Takeaways and Call to Actions

3. Problem statements and Opportunities
It takes a long time to upstream NSH patches to Open vSwitch (OvS*)
Needs a high performance data plane alternative to support service function chaining solution for Network Function Virtualization (NFV)
Opportunities
VPP in FD.io* offers a Data Plane Development Kit (DPDK) accelerated high performance data plane implementation
VPP, NSH_SFC and Honeycomb releases fully support NSH
Honeycomb provides Opendaylight*-friendly NETCONF and RESTCONF interfaces for integration
