摘　　要：针对计算机网络状况监控领域的实际需要,提出了基于NetFlow的流量采集技术。相比其它的流量采集工具,NetFlow的流量采集技术具有配置方便,费用低,占用资源小的优点。分析了NetFlow交换技术采集网络流量信息的实现原理。并从计算机网络的网络层和传输层2个方面,讨论了NetFlow网络流量采集技术在网络信息安全方面的相关应用。This paper proposes the network flux collection technique based on net flow according to practical requirements in the field of monitoring the status of computer network. Compared to other flux collection tools, NetFlow has advantages of convenient configuration, low cost and small occupied resources. This paper analyses the principle of realization of NetFlow exchange technique collecting network flux information. Then both from the network layer and transport layer, the paper discusses some relevant applications of NetFlow network flux collection technique using in network information security areas.
