基于边缘流量测量的算法研究

Research of IP Network Measurement Based on Edge

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 networks, the understanding of network behavior is of great importance for network management, network planning and network development. And the measurement of network traffic is the foundation for the study of network behavior. The current measurements of network traffic demand the measurement at the inner core node of the network, thus requiring fairly large network overhead. The paper describes the traffic measurement in edges of the network. Then based on this measurement, the network traffic in every link is estimated. In this paper, the algorithm for estimating the network traffic is proposed, and the measurement overhead of network traffic is thus saved. Finally, the simulation indicates that this algorithm is feasible and practicable.
