Abstract: 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.
