Webcess (RDMA) implements the entire transport logic in hardware network interface card (NIC) and allows di-rect access to remote memory, mostly bypassing CPU. Therefore, RDMA … WebRDMA transmission works in NICs with three queues: Send Queue (SQ), Receive Queue (RQ), and Completion Queue (CQ). When an RDMA application starts to work, it must create its SQ, RQ, and CQ in the RDMA NIC, and registers regions in memory for its processing. The work scheduling unit of RDMA is a Queue Pair (QP), which consists of one SQ and one RQ.
