随着高速网络技术的发展,大多数高校引入了千兆网,校园网络日益规模化和复杂化,使得实时在线的流量测量变得比较困难,基于抽样的流量测量方法作为一种可扩展的测量技术已成为人们经常采用的一种有效的流量测量技术。本文采用＂弱化的贪心算法＂确定各网段的最佳测点,并采用IP掩码匹配的分布式抽样测量技术将各测量点同步采集的流量经抽样后存储到服务器的不同储存区域,然后根据测量目标对各网段采集的流量进行汇聚、分析和统计。从节约成本出发,本文引入了双机协作抽样技术进行测量,此双测量主机系统充当了服务器、测量器和分析器角色,整个测量无需专用测量器和服务器,可以基本取代市场专用的流控测量设备,能实现对整个校园网流量的掌控。

With the rapid development of network technology,Most campus into a Gigabit Network,Campus network increasingly large-scale and complicated,which makes the real-time on-line flow measurement becomes more difficult,Based on sampling method of flow measurement as a scalable measurement technology has become a frequently used and effective flow measurement technology.This paper adopts＂ weakening of the greedy algorithm＂ to determine the segment of the best measuring point,And the use of IP mask matching distributed sampling measurement technology of each measuring point synchronous acquisition flow through sampling after storage to the server in different storage areas,Then according to the measurement of the target on the network acquisition flow gathering,analysis and statistics.From the view of saving cost,this paper introduces two collaborative sampling technique,the double measuring host system acts as a server,measuring apparatus and analyzer role,the entire measurement without a special measuring device and the server,can replace the market special measuring equipment,can achieve the whole campus network flow control.
