RoCEv2 (server)

The server receives the RoCEv2 flow and can generate congestion notifications. Compared with the client, the server does not have Targets, Rate settings (PPS), or Payload settings; the client defines the load. The RDMA command, InfiniBand MTU, and DCQCN settings are also client-side only.

  1. Receiver — same as for the HTTP server plugin.
  2. IP header (L3) — same as for the HTTP server plugin.
  3. Server-side RoCEv2 settings:
