随着互联网的发展,理解网络行为对于网络管理、规划和发展都有重要意义,网络流量测量是研究网络行为的基础。现有的网络流量测量方法大都需要在网络的内部核心节点处进行测量,需要的网络开销比较大。文中在网络边缘处进行流量测量,然后根据边缘测量结果估计网络各个链路上的流量,提出了网络流量估计算法,节省网络测量开销。最后经过仿真证明该算法可行。
With the development of the Internet, understanding network behavior is of great significance to network management, planning and development. Network traffic measurement is the basis for studying network behavior. Most existing network traffic measurement methods need to be measured at the internal core nodes of the network, and the network overhead required is relatively large. In this paper, traffic is measured at the edge of the network, and then the traffic on each link of the network is estimated based on the edge measurement. A network traffic estimation algorithm is proposed to save the network measurement overhead. Finally, the simulation shows that the algorithm is feasible.
