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.

Abstract: 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.

Abstract: A system includes a bus interface and circuitry. The bus interface is configured to communicate with an external device over a peripheral bus. The circuitry is configured to support a plurality of widgets that perform primitive operations used in implementing peripheral-bus devices, to receive a user-defined configuration, which specifies a user-defined peripheral-bus device as a configuration of one or more of the widgets, and to implement the user-defined peripheral-bus device toward the external device over the peripheral bus, in accordance with the user-defined configuration.

Abstract: A combined request may be used to reduce a number of communications between a client and server to establish a remote connection. The combined request can include one or more add session requests along with one or more add queue pair (QP) requests. The server, receiving the combined request, may then evaluate each request in turn to determine whether a session can be established and then to add a QP to that session and provide, in a combined reply, connection information back to the client. The client may then verify the connection information and begin transmitting data. As a result, a total number of communications between the client and server can be reduced.
