Strategy and Methods for Fault Analysis for Experiment Mission IP Networks

针对试验IP（互联网协议）网建设和使用中遇到的网络问题,从TCP（传输控制协议）/IP网络原理和试验IP网的结构模型出发,对网络故障排查方法进行了总结,给出网络分层模型分析法、网络连接结构分析法和网络检测分析法相结合的故障排查策略。对某次测控信息联调中接收不到网络数据的真实故障案例进行了分析,运用网络检测工具对故障进行排查,依据网络结构对故障进行定位,依据网络协议对故障进行分析,验证了该方法可以使问题分析层次清晰、定位准确。

Starting from the principle of TCP （Transmission Control Protocol）/IP （Internet Protocol） network and the structure model of experiment mission IP networks, this paper summarizes methods for detection of network faults, which are often encountered in development and operation of experiment mission IP networks. A trouble- shooting strategy combining layered model analysis method, network connection structure and network detection a- nalysis method is given. The strategy and methods are used in trouble-shooting a fault during a TT^C integration and test task where network data was not received. Network detection tools are used in fault analysis. Network fault is located according to the network structure. The fault is analyzed according to network protocols. It is found that the strategy and methods help locate the fault accurately and enable logical and clear analysis of the fault.
