| Abstract: |
Big data has raised new challenges to data communication and transmission capacity. RDMA (Remote Direct Memory Access) Transport Protocol can reduce the communication delay of big data through kernel memory bypass technology and zero-copy technology. This paper introduced RDMA technology for the network performance optimization of BBCP (Babar Copy Program), a big data network file copy tool. Also, transmission queue-oriented Tetris Scheduler algorithm, I/O performance optimization and buffer memory optimization technique were introduced to realize RDMA-based file transfer tool, OBCP (Optimized Babar Copy Program). The experiment results verified that the optimization method could decrease the file transmission time to one-tenth of original BBCP and improve the performance by 50 % compared with related works.
