摘　　要：针对不同安全等级网络之间数据单向传输的需求,提出一种单向代理传输协议,该协议运行在计算机网络体系中的网络层,是一种非IP协议,介绍该私有协议的报文结构、网络模型和封装过程。基于该私有协议,在申威国产化平台上设计一款单向数据传输设备,分析设备适用的业务场景,搭建测试实验环境,对设备的文件传输带宽、TCP报文传输时延和UDP数据传输时延等性能进行测试,验证了单向代理传输协议在单向数据传输设备中的网络传输性能。Aiming at the requirements of data one-way transmission between different security level networks,a one-way proxy transfer protocol(OPTP)was proposed.It was used to the network layer in computer network architecture,and was a kind of non-IP protocol.The message structure,network model and encapsulation process of OPTP were introduced.Based on OPTP,a one-way data transmission equipment on localized Shenwei platform was designed,the applicable business scenarios for the equipment were analyzed.A test experiment environment was built to test the file transmission bandwidth,TCP packet transmission delay and UDP data transmission delay of the equipment,and the network transmission performance of OPTP in one-way data transmission equipment was verified.
