Hi All, I maybe not clearly said in today’s NVO3 meeting, pls allow me to reiterate the OAM data plane requirements on the mail list.
Currently NVO3 data plane encapsulation only includes one OAM flag, it is used for Ping/Trace similar applications. This kind of OAM application is initiated by operators for network connectivity verification, normally when network failure occurs. There is another OAM requirements of real time OAM or synthesizing OAM. It can be used for packet loss detection in real time. When ingress NVE receives traffic from local TS, it gets packet statistics, and mark(coloring) the OAM flag relying on local policy when it performs NVO3 encapsulation. When egress NVEs receives the traffic, it decapsulates NVO3 encapsulation, and gets packet statistics with the real time OAM flag marking. By comparing the packet number of ingress NVE and the sum of all egress NVEs, packet loss can be deduced. This method can be applicable for both unicast and multicast traffic. Local policy on ingress NVE is configured by operators or automatically acquired from centralized orchestration. Thanks weiguo
