The SMB2 Remote Direct Memory Access (RDMA) Transport Protocol allows upper-layer packets to be delivered over RDMA-capable transports such as iWARP [RFC5040] and [RFC5041], Infiniband [IBARCH] or RoCE [ROCE], while utilizing the Direct Data Placement (DDP) capabilities of these transports. One upper layer that optionally uses the SMB2 Remote Direct Memory Access (RDMA) Transport Protocol is the Server Message Block (SMB) Protocol Versions 2 and 3 [MS-SMB2].
