摘　　要：随着以太网技术的不断发展,以太网已成为未来通信领域的核心技术之一。而影响用户业务体验服务质量(QoS)的参数通常包括时延、抖动、丢包率等。对于实时的语音和视频业务来说,业务数据的端到端时延则最为关键。主要在熟悉以太网标准的基础上,总结端到端时延的主要构成因素,对各个时延所占比重进行理论分析。最后对10G/100G以太网进行仿真模型设计,验证了理论分析的正确性。With the rapid development of the Ethernet technologies,Ethernet has become one of the core technologies in future communication domain.And user experience may be affected by QoS parameters of services typically include delay,jitter,packet loss rate and so on.For real-time audio and video services,end-to-end delay of data is most critical.Based on the exist Ethernet standards,summarized the main factors of end-to-end delay,and theoretical analysis of different delayes on the proportion of totoal delay.Finally carried out a simulation model designed to 10G/40G/100G Ethernet,which proves the design is feasible and correct.
