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。
Operation, management and maintenance (OAM) mechanism is the key to strengthening the management and control of packet transport network. Following the transmission of Multi-Protocol Labeling (T-MPLS) technology, MPLS-TP has absorbed the advantages of Layer 3 IP, Layer 2 PWE3 and Layer 1 TDM / OTN technologies and inherited and developed OAM technologies. As the mainstream technology of packet switched network (PTN), MPLS-TP must possess strong OAM technology to be more competitive with the market. Mainly carries on the research to its hardware realization method, first has detailed the MPLS-TP network OAM network model and the main function. Focusing on the implementation of OAM functional hardware are discussed, the realization of the program, detailed description of the logic of each functional module process and the specific circuit. The program also needs further system-level verification and will be gradually completed in future research.
