It seems like kernel RDMA protocols are all getting IANA-assigned port numbers that alleviates the need for TCP/RDMA port unification. NFSRDMA and RDS are two. But user applications like mvapich2 and other mpis often let the stack choose a local port number on-which to bind/listen.
Hi Steve,
You have mentioned the listeners, but what about the ports used for the connection itself? isn't it correct that when the TOE stack accepts the rNFS connection request to port X - still a different port Y would be used for the connection itself ? but if the Linux TCP stack would have (say) iperf bind to port Y then you are again in troubles - am I missing anything here?
