短波IP网络中IP代理的设计与实现

Design and implementation of IP client in HF IP network

短波IP网络是未来军事短波通信网络的发展方向,IP代理是短波IP网络的关键组成部分,负责IP数据报和短波报文之间的转换,以及IP地址和短波子网地址间的映射。基于国内外短波网络发展现状,利用Linux系统中的Tun/Tap设备实现了IP代理与系统内核之间的互通,并提出短波网络内IP数据报的转发流程。

HF IP network is the prevalent direction of military Hign-Frequency communication network m the future. The IP client, which takes charge of switch over between IP datagram and HF message, and the mapping between IP address and HF sub-network address at the same time, is the key composition of HF IP network. Based on the recent research status in the world, the Tun/Tap device in Linux system is made use of to connect the IP client application and system kernel, and a program design about IP flow in I-IF network is provided.
