摘　　要：针对网络时间协议PTP在以太网上的应用,研究了PTP协议的功能和流程,提出了PTP协议在NS2平台下的实现方案,并通过仿真研究了PTP协议在以太网环境中的同步性能。研究结果表明,IEEE 1588标准的PTP协议在以太网上具有极佳的同步性能,其同步精度可以达到ns级别,并且具有良好的抗噪能力。数值仿真结果说明了该仿真方案的有效性和可行性。For the application of network time protocol PTP on ethernet, this paper has made researches on the fucntion and process of PTP and proposed the implemenation soltuion of PTP on NS2 platform. The synchornization performace of PTP on ethernet has been also investigated in this paper through simulation, which indicated that IEEE 1588 PTP on ethernet has excellent synchronization performance which could reach ns level resolution and has good anti-noise capability. The simulation result has proved the validity and feasibility of the proposed solution.
