RDMA Transmission Control Method: Using Network Resource Allocation For Wide-Area Data Collection

Cyber-physical systems (CPS) are expected to monitor facilities, vehicles and infrastructure with sensors, such as cameras, and analyze the resulting data to intelligently control objects. CPS requires a large amount of data to be collected from a large number of objects located in a wide area, and thus requires a data collection method that has a low reception load within finite network resources. Therefore, we propose a method to adjust network resource allocation: Remote Direct Memory Access Transmission Control Method(RDMA-TCM). The RDMA-TCM is implemented in the server and evaluated in terms of transmission rate and processing delay. Our network experiments show that the CPU load during data collection is as low as that of standard RDMA while preventing network resource occupancy.
