摘　　要：针对当前的网络现状和发展趋势 ,对以IP/MPLS为基础的IP骨干网中 ,实施业务流量工程是必需的 ,业务流量矩阵的测量是实现业务流量工程的最基本的要求。笔者对当前一些主要测量方法的不足进行了分析 ,提出了基于MPLS的IP骨干网的业务流量工程模型和LSP级的业务流量矩阵的测量模型 ,以及相应的路由算法。业务流量矩阵的测量方法的优点在于 :测量仅仅限于网络的边缘节点而不涉及核心节点 ,因而对网络资源的耗费少 ,为解决当前一些主要测量方法的缺陷提供了新的思路 。On current network actuality and development trend, it is necessary to put traffic engineering in practice in IP backbone network on IP/MPLS. The essential demand in actualizing traffic engineering is traffic matrix measurement. After analyzing the defect of current measurement method, traffic engineering model and traffic matrix on LSP in IP backbone network based on MPLS, or relevant routing algorithm are researched. The merit of the traffic matrix's measurement method is that implement of measurement is only located in the edge node; therefore, network resource's cost is lower and it offers a new train of thoughts for resolving the flaw of current main measurement methods, moreover, and condition for actualizing traffic engineering.
