[openstack-dev] [Neutron] support of NSH in networking-SFC

Hi Uri,

Current networking-sfc API allows the user to specify the data path SFC encapsulation mechanism and NSH could be one of the encapsulation options.
But since OVS release has not supported the NSH yet, we have to wait until  NSH is added into OVS and then start to support the NSH encapsulation mechanism in the data path.

AFAIK, it is the position of Neutron to have any OVS related new features developed inside the OVS community.

Hi Armando

As an industry we are working on SFC for 3 years or so (more?). Still to date, we are told we can’t get Neutron or even a Stadium project e.g. networking-SFC to support NSH (in IETF LC phase) because OvS has not supported NSH. Is this an official position of Neutron that OvS is the gold standard to support any new feature?

We have seen OvS support other overlays that are not ahead of VXLAN-gpe in the IETF.
