【摘要】 通过对Internet进行不同地点、时间段和数据包大小的传输时延统计 ,得到了网络传输时延近似符合正态、指数分布或对数正态分布的统计规律。根据Internet的统计模型建立了以Internet仿真器为基础的网络遥操作系统仿真环境。Internet仿真器提供统计模型的三种分布和与实测数据相同分布的时延 ,能够提高系统设计与仿真的灵活性和减少系统的开发周期更多还原

【Abstract】 An internet statistic model was made by analysis of the time delay of different distance, packet size and probing time The distribution of round trip time delay is exponential, normal or logarithm normal Based on the internet statistical model, a simulation environment for Web based teleoperation and its internet simulator are developed The internet simulator, providing three statistical distribution as well as real data distribution, can improve the flexibility and reduce the developing time of the system更多还原
