分布式网络流量监测

Distributed Monitor on Network Traffic

分析2种现行网络流量监测技术:利用标准的网络管理方法记录IP流量和利用NETFLOW的方法进行流量统计。针对这2种方法的局限性,提出分布式网络流量监测方法。该方法采用Client/Server结构,局域网各个终端参加流量统计,并将结果传送给流量监测服务器。该方法适合大型局域网的流量监测,具有良好硬件适应性,大大降低了流量监测服务器的工作量,提高了网络性能。

This paper analyzes two kinds of technology about network traffic monitor： scoring up traffic using the standard network monitor method and the NETFLOW method. For the defects of the two methods, it advances the distributed monitor on network traffic, uses the Client/Server structure. Every terminal in LAN joins monitor traffic and sends traffic data to the traffic monitor server. The tact demonstrates that this technology is suit for the traffic monitor of large LAN. It diminishes the work load of traffic monitor server clistinguishably and elevates the performance of Internet, at the same time, it displays great adaptability for hardware.
