"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. " - Rdma throughput
