Systems and methods enable session sharing for session-based remote direct memory access (RDMA). Multiple queue pairs (QPs) can be added to a single session and/or session group where each of the QPs has a common remote. Systems and methods may query a session ID for an existing session group and then use the session ID with an add QP request to join additional QPs to an existing session. Newly added QPs may share one or more features with existing QPs of the session group, such as encryption parameters. Additionally, newly added QPs may be configured with different performance or quality of service requirements, thereby isolating performance, and permitting true scaling for high performance computing applications.
