摘　　要：针对实验过程中以太网传输的丢包问题,使用OMNEST进行仿真建模,利用精确的系统描述,复现所出现的问题,进行丢包和端到端时延的研究。通过仿真分析定位问题,发现ARPCache中目的地址的超时或定期清空导致故障发生。基于此问题提出解决方案,为解决问题提供支持。In order to overcome the packet loss occurring in Ethernet transmission in the process of experiment,OMNEST is adopted to conduct simulation and modeling,and the precise system description is used to recur the occurred problem to im-plement the research of packet loss and the delay from terminal to terminal. It is found in simulation analysis of positioning prob-lem that the timeout or regular interval clear of destination addresses in ARPCache may cause the fault. The solutions for the problem is proposed in this paper. It provided a support for solving the question.
