Abstract:
Waiting for connection establishment can be inefficient during remote direct memory access (RDMA) transport for Gigabit Ethernet. Aiming at solving this problem, a hardware accelerated dynamic RDMA method is proposed in this paper. This method allows starting RDMA transport at the same time with connection establishment by sending packages first to indirection buffer in network interface card (NIC) and copying them later to host memory. The terminal models of dynamic RDMA method are built and the simulation platforms for perform experiments are developed. Experimental results show that the dynamic RDMA method not only can solve the long waiting problem of connection establishment with little extra hardware cost, but also can provide higher transport performance compared with traditional RDMA methods.
