This document describes IBM's Shared Memory Communications over RDMA
(SMC-R) protocol. This protocol provides Remote Direct Memory Access
(RDMA) communications to TCP endpoints in a manner that is
transparent to socket applications. It further provides for dynamic
discovery of partner RDMA capabilities and dynamic setup of RDMA
connections, as well as transparent high availability and load
balancing when redundant RDMA network paths are available. It
maintains many of the traditional TCP/IP qualities of service such as
filtering that enterprise users demand, as well as TCP socket
semantics such as urgent data.
