Abstract: Multipathing for session-based remote direct memory access (SRDMA) may be used for congestion management. A given SRDMA session group may be associated with multiple SRDMA sessions, each having its own unique 5-tuple. A queue pair (QP) associated with the SRDMA session group may provide a packet for transmission using the SRDMA session group. The SRDMA session group may enable the packet to be transmitted using any of the associated SRDMA sessions. Congestion levels for each of the SRDMA sessions may be monitored and weighted. Therefore, when a packet is received, an SRDMA session may be selected based, at least, on the weight to enable routing of packets to reduce latency and improve overall system efficiency.
