WebRDMA operations require extending the transport protocol by defining a new opcode , its respective header and enhanc ing InfiniBand implementations to support this new behav ior . A more robust way of extending RDMA without requir ing an expanding set of opcodes is to register computer code by associating it with a code key similar to a memory ...

WebFeb 4, 2024 · This document specifies the second version of a transport protocol that conveys Remote Procedure Call (RPC) messages using Remote Direct Memory Access (RDMA). This version of the protocol is extensible. ¶ WebAPI used to setup reliable, connected and unreliable datagram data transfers. It provides an RDMA transport neutral interface for establishing connections. The API is based on sockets, but adapted for queue pair (QP) based semantics: communication must be over a specific RDMA device, and data transfers are message based.
