Research On InfiniBand Network Protocol Layer Software Technology

With the rapid development of computer hardware equipment and the popularization of big data technology,high-performance network data transmission has gradually become a hot topic of current research.InfiniBand(IB)is a high-bandwidth,low-latency network communication technology,which is widely used in highperformance computing and data center network scenarios.This paper studies the software technology of the protocol layer of InfiniBand.In order to solve the difficult problem of transmission speed in real-time streaming data transmission,this paper proposes a data distribution software based on the InfiniBand data link based on the heterogeneous embedded InfiniBand board of ARM and FPGA,which realizes high-speed real-time streaming data distribution from embedded InfiniBand boards to multiple target server nodes.To simplify the network architecture of InfiniBand data distribution software,the embedded IPoIB software is designed,the TCP/IP protocol and the InfiniBand protocol conversion is supported on the embedded InfiniBand board,and the sending and receiving of IP packets on InfiniBand links is realized.The test results show that the data transmission speed of the InfiniBand data distribution software designed in this paper can be stabilized above 9GB/s,and software can correctly handle system exception.The embedded IPoIB protocol conversion software designed in this paper runs correctly on the embedded InfiniBand board,can support the sending of multiple IP packets,and correctly parse the received IPoIB data packets.
