Sockets Direct Protocol (SDP) is a byte-stream transport protocol implementing the TCP SOCK_STREAM semantics utilizing transport offloading capabilities of the InfiniBand fabric. Under the hood, SDP supports Zero-Copy (ZCopy) operation mode, using the InfiniBand RDMA capability to transfer data directly between application buffers. Alternatively, in Buffer(More)
Sockets Direct Protocol (SDP) is a byte stream protocol that utilizes the capabilities of the InfiniBand fabric to transparently achieve performance gains for existing socket-based networked applications. In this paper we discuss an implementation of Zero Copy support for synchronous send()/recv() socket calls, that uses the remote DMA capability of(More)
