摘要
操作、管理、维护(OAM)机制是加强对分组传送网络的管理和控制关键。继传输多协议标签(T-MPLS)技术以后,MPLS-TP吸收了三层IP、二层PWE3和一层TDM/OTN技术的优点,将OAM技术进行了继承和发展。作为分组交换网络(PTN)的主流技术,MPLS-TP必须拥有强大的OAM技术才能更加具备市场竞争力。主要对其硬件实现的方法进行了研究,首先详述了MPLS-TP网络的OAM网络模型及主要功能。重点对OAM功能硬件实现方式进行了讨论,提出了实现方案,详述了各个功能模块的逻辑处理过程及具体电路实现。方案还需要进一步的进行系统级的验证,将在今后的研究中会逐步完成。
OAM（Operation,Administration,and Maintenance） mechanisms is thekey tothe managementand control enhancement of the packet transmission network.Based on the T-MPLS technology,MPLS-TP absorbs the advantages of IP,PEW3 and TDM/OTN,and inherits and develop the OAM technology.As the main technology of PTN,MPLS-TP must have the strong OAM technology,and thus could increase the market competitiveness.The method for its hardware implementation is studied.The network module and main function of MPLS-TP are given.This paper proposes the hardware design scheme of the OAM function,describes the process of each logic module,including the specific circuit implementation.The method also requires further system-level verification,and would be completed step by step in the future.
