【摘要】 该文设计并实现了一个基于LINUX平台的通用广域网模拟器WEMU。它可以逼真地在局域网环境中仿真出广域网的延迟、丢包、断路等多种特性,为各种基于广域网的试验提供一个成本低廉、仿真效果好的仿真平台。同时具有良好的灵活性和可扩展性。文章讨论了WEMU的总体设计和实现的技术要点,并给出了具体的测试结果。更多还原

【Abstract】 This paper designs and i mplements a WEMU system which is an universal internet simulator bases on LINUX ,It can efficiently emulate behavior of internet in LAN,such as latency and lo ss of packets delivered over WAN,not only provide a low-cost and good simulati on effect platform for those experiments based on WAN.but also has good flexib ility and expansibility.This paper discusses the over-all design and key techn ical point of WEMU,as well as its test results.更多还原
