Minimal Viable Requirement ++++++++++++++++++++++++++ Deploy a complete SFC solution by integrating OpenDaylight SFC with OpenStack in an OPNFV environment. Detailed Requirements +++++++++++++++++++++ These are the Fraser specific requirements: 1 The supported Service Chaining encapsulation will be NSH VXLAN-GPE. 2 The version of OVS used must support NSH. 3 The SF VM life cycle will be managed by the Tacker VNF Manager. 4 The supported classifier is OpenDaylight NetVirt. 5 ODL will be the OpenStack Neutron backend and will handle all networking on the compute nodes. 6 Tacker will use the networking-sfc API to configure ODL 7 ODL will use flow based tunnels to create the VXLAN-GPE tunnels Long Term Requirements ++++++++++++++++++++++ These requirements are out of the scope of the Fraser release. 1 Dynamic movement of SFs across multiple Compute nodes. 2 Load Balancing across multiple SFs 3 Support of a different MANO component apart from Tacker
