软件实现.Netflow流量处理的关键技术和算法

Key Software Technique and Algorithm of Analyzing Netflow Traffic Data

主要以Cisco的Netflow技术为应用背景,讨论如何采用软件技术和算法来解决网络流量采集和处理所涉及到的性能瓶颈问题,主要 涉及数据的快速存储和访问、TOPN排序技术这两个方面。该文假设读者对各种传统排序算法、Netflow技术和计算机原理都有一定的了解。

This paper discusses how to use software technology and algorithm to solve the problem of network traffic, based on Cisco netflow technique. One is about rapid visit and update of memory data, the other is the algorithm of TOPN sorting. Readers of this article need both knowledgs of Netflow technique and software development.
