本文描述了一种跟踪驱动的，快速的仿真方法，适用于处理的性能评估的多路复用的异构业务流的可变比特率和长寿命的串行相关提供路由器在互联网上。模拟互联网的一个挑战是每个感兴趣的事件都需要大量的事件，例如数据包的丢失或过度延迟。在本文中的轨迹驱动方法的仿真效率提高，通过使用重要性采样，以激发轨迹的星座丢失和长延迟的可能性更大。该方法已成功地应用于异构MPEG编码视频流复用仿真中
This paper describes a trace driven, fast simulation approach applicable to deal with the performance evaluation of a multiplex of heterogeneous traffic streams with variable bit rate and long lived serial correlation offered routers in the Internet. A challenge with simulations of the Internet is the huge number of events that are needed for each event of interest, e.g. the loss or excessive delay of a packet. The simulation efficiency of the trace driven approach in this paper is improved by use of importance sampling to provoke constellation of traces where the loss and long delays are more likely. The approach is successfully applied to speedup the simulation of multiplexing of heterogeneous MPEG encoded video streams
