Hi, I just checked wiki page of QoS support in Contrail. https://github.com/Juniper/contrail-controller/wiki/QoS #Release QOS config and forwarding class will be implemented as part of 3.1 Queueing in kernel mode vrouter will be implemented as part of 3.2 Queueing in DPDK mode vrouter will be implemented as part of 4.0 Egress marking and queueing is currently not planned.
I wonder whether QoS of DPDK mode vrouter is already supported in R3.2 or not. If not, which part is missing. Your help will be greatly appreciated. Since I have already built contrail-vrouter-dpdk based on DPDK-2.1.0 Moreover, I have found QoS related symbols in it as follows.
