Hi Selvam,

Yes I agree this does need to be discussed. There could be a couple methods
in achieving this:


   - The virtual bridge on the hypervisor of the NVE can handle the
   rate-limiting ingress or egress from the TES on the VAP.
   - If the encapsulation is IP between the NVE, we could ensure that
   appropriate DSCP/ToS markings are copied into the IP header based on
   configured mappings of tenant QoS priority. This way standard physical
   network devices can also appropriately provide the intended per hop
   behavior.
   - The IP ToS or DSCP values from packets generated from TES could be
   simply copied into encapsulation IP header; if a corresponding VAP or
   policy existed on the VNI.

Just some quick thoughts on this at midnight ...

Kind regards,
Truman
