This project is part of ONOSFW for OPNFV. In the first version (Emu), the The SFC creation is primarily driven by Openstack Neutron. The SFC component in ONOS implements the SFC creation requests from Openstack Neutron. All the required information for creating a service chain are supplied by Neutron using REST based APIs. Using these information, the SFC component prepares the flow rules as per the IETF NSH header and downloads the flow rules into OVS (OVS version 2.5.90 with official NSH Patch - https://github.com/yyang13/ovs_nsh_patches)

Architecture

SFC is implemented as a bundle within the VTN application in ONOSFW.
