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 ...
