High-performance data transfer for full data replication between iter and the remote experimentation centre

A high-performance data transfer method has been developed for the Remote Experimentation Centre (REC) of ITER in Japan for the first time. The developed technology shows the technical feasibility to establish the REC with full data replication between ITER and REC for remote experiments. Test results showed that it achieved a data transfer rate of approximately 7.9 Giga-bits per second (Gbps) on a 10-Gbps network. The new double-layer storage structure can accelerate the storage read/write speed up to 2 GByte/s. Moreover, the Internet and a layer-2 virtual private network (L2VPN) comparison tests demonstrated that the latter is superior in both security and speed. This technology shows great potential for near real-time full data replication between ITER and REC, which may provide a new style of world-wide remote experimentation
