业务量矩阵估算算法的设计与实现

随着互联网的飞速发展和网络业务的日趋丰富，网络规模和业务量急速增长，而目前的Internet不能完全满足网络各方面的应用要求，因此实施流量工程显得十分重要。主要研究流量工程中业务量矩阵的估算算法。实验系统以Network Simulator 2作为网络拓扑结构和数据的生成环境及后期算法验证环境，根据现有的理论和实验依据搭建实验框架，运用Java语言实现离线的业务量矩阵的估算算法，最后通过大量的仿真实验验证、比较、改进算法的有效性，为进一步的研究提供实验数据支持。

Design and implementation of algorithm of traffic matrix estimation

With the fast development of intemet and the abundance of network traffic, the scale of network and traffic are increasing greatly. However the current intemet can not meet all of the needs of people, so the traffic engineering is very important. The algorithm of traffic matrix estimation in the traffic engineering is presented, The system is based on the network simulator 2. To get the network topology and data before the experiments and to validate the algorithm after the experiments, the experiment structure through the current research and some theories about it is built; then the off-line algorithm of traffic matrix estimation using Java is completed; finally, by using many simulating experiments to validate, the algorithm is compared and improved, and some supports to the further research is given.
