Abstract (in Japanese) (See Japanese page) 
(in English) With the growth of cloud computing, the demand for higher bandwidth and lower latency in data center networks continues to increase. In the future, high-bandwidth and long-distance optical networks may be used to expand interconnection between multiple remote sites. In conventional data centers, Remote Direct Memory Access (RDMA) has been implemented as a transport method for fast and reliable data transfer. However, since RDMA is a Queue-based connection-type communication model, its transfer performance degrades significantly as the transmission distance becomes longer. In this paper, we propose a technique to improve the data transfer performance by placing a transparent accelerator in the network and pseudo-returning the connection acknowledgement from the accelerator. Through implementation evaluation, we show that the performance of RDMA can be maintained at high levels even when the transmission distance becomes long.
