Transport modes

Edit online

The transport modes establish a connection for the queue pair.

The following transport modes are supported
  • Reliable connection (RC)
    • Each queue pair (QP) is associated with another QP
    • Messages that are transmitted by the send queue of one QP are reliably delivered to the receive queue of another QP.
    • Packets are delivered in order.
    • An RC is similar to a TCP connection.
  • Unreliable datagram (UD)
    • No actual connection is formed between the QPs.
    • The UD mode is similar to a UDP connection.
