以太网电路仿真技术的时钟同步研究

Research about clock synchronizationof ethernet circuit emulation technology

在数据业务膨胀的今天,实现电信级的电路仿真业务是MEF的目标.而时钟同步和时钟恢复则是电路仿真业务面临的主要技术挑战.本文简要介绍电路仿真业务的基本概念,详细的介绍了时钟同步问题,并对实现时钟同步给出了相关的办法.以达到更好地实现电路仿真业务.

With the expanding of data services,the realization of carrier-class circuit emulation services over ethernet network is the goal of Metro Ethernet Forum(MEF).Then the clock synchronization and recovery are the main technology challenge of circuit emulation services.This paper simply introduces the basic conception of circuit emulation services,particularly issues of clock synchronization,also some methods of realizing clock synchronization are given for achieving better circuit emulation services.
