Yes, SCTP is similar in those regards.
SCTP creates a connection and then multiplexes a set of sessions over it. You can conceptually think of it as akin to IB RD but where all QP are bound to the same EEC.
SCTP preserves all QP to QP semantics, including
buffers posted to specific
buffers and credits. So SCTP will allows multiple
in-flight messages for each
RDMA stream in the
association.
