摘要
介绍了IP网络中合法监听的相关知识,对比了网路数据流监听的2种方案:简单监听和DECON监听,分析了2种方案的优缺点,提出了一种更优的监听方案,此方案将监听点和数据流转化为二分图的2个集合,多次采用匈牙利算法完成监听点和数据流的匹配。此方案不仅使所用的数据流得到监听,而且使得数据流平均的分配到监听点上,有效解决了前2种方案中某个别监听点负载过重和引起的网络拥塞问题。
The knowledges of Lawful Interception in IP network is described. Two programs of data stream monitoring in network are introduced （the simple monitoring and Decentralized Coordination monitoring）, both advantages and disadvantages of the two programs are analyzed, and an optimized monitoring program is presented. Monitor points and data flow are made into two sets of bipartite graphs in this program, and the Hungarian algorithm is used to complete monitoring points and data flow matching. By this, not only all data flow can be monitored but also the data stream is distributed equally to monitor the point, the overloaded of monitoring point and the network congestion problems are solved effectively.
