In our research project, we have obtained the following achievement in summary.1. We have proposed an MMPP model to describe long range dependency in traffic and validated its effectiveness.2. We have developed a simulation model to evaluate the effect of ATM switches on the QoS of MPEG2 traffic in terms of the number of stages.3. We have monitored cell emission intervals in an ATM network and found that their statistic characteristics can be described by the nature of groups of eight cells and that of individual cells.4. We have collected data on cell jitter in an ATM network and carried out statistical investigation.5. We have mathematically analyzed the performance of CSMA/CD which is suitable for multimedia communication in LAN environment.6. We have monitored cell streams from MPEG2 sources and investigated their Hurst parameters by means of four different methods.7. We have developed a simulation model by using OPNET to evaluate cell jitter in ATM networks.8. We have carried out the performance analysis of CSMA/CD-PS which is an efficient protocol for wireless LANs.9. We have proposed a mathematical model to analyze the performance of SVCC through IP over ATM.

在我们的研究项目中，我们取得了以下成果：1.提出了一种描述流量长相关性的MMPP模型，并验证了该模型的有效性。建立了ATM交换对MPEG2业务服务质量影响的仿真模型，从级数的角度评估了ATM交换对MPEG2业务的影响。我们监测了ATM网络中的信元发射间隔，发现它们的统计特性可以用8个信元组的性质和单个信元的性质来描述。我们收集了ATM网络中信元抖动的数据，并进行了统计调查。对适合在局域网环境下进行多媒体通信的CSMA/CD协议的性能进行了数学分析。我们监测了来自MPEG2信源的信元流，并通过四种不同的方法研究了它们的赫斯特参数。我们利用OPNET开发了一个仿真模型来评估ATM网络中的信元抖动。对无线局域网中的高效协议CSMA/CD-PS进行了性能分析。我们提出了一个数学模型来分析基于IP over ATM的SVCC的性能。
