摘要
大规模密集网络在受到网络攻击和流量过载时,容易导致网络路由协议失效,出现网络堵塞、延迟和丢包等受损状态。因此,提出一种网络受损状态评估平台的设计方法。通过对网络受损下的网络通信的丢包检测、流量异常检测和入侵检测等方法进行综合评价和系统评判。平台的硬件设计包括电源电路、异常流量数据加载电路、复位电路模块、A/D电路、接口电路。在Visual DSP++4.5软件开发平台实现平台的软件开发。仿真结果表明,该平台进行网络受损状态评估的可靠性较好,对网络受损后异常流量等参量的检测输出较准确,状态评估输出的鲁棒性较高。
A design method of network damaged state evaluation platform is proposed in this paper. The detection methods of packet loss, traffic abnormal and intrusion phenomena in network communication are adopted to carry out comprehensive evaluation and system evaluation when a network is damaged. The platform hardware design includes power circuit, abnormal traffic data load circuit, reset circuit module, A/D circuit and interface circuit. The software development for the platform was re- alized on Visual DSP＋＋ 4.5 software development platform. The simulation results show that the platform has better reliability in network damaged state evaluation, high accuracy in detection output of abnormal flow parameter when network damage occurs, and high robustness in state evaluation output.
