分布式路由器操作维护管理系统的设计与实现

路由器操作维护管理（OAM）系统负责对路由器进行操作和管理，它是由路由器正常运行的保证，是路由器中的重要模块。高性能路由器通常采用的分布式体系结构，这就对操作维护管理提供了新的要求。本文对路由器操作管理进行了深入的研究，首先介绍了路由器操作管理的设计要求和研究现状，然后介绍了清华大学研制的高性能多协议路由器的软硬件体系结构和其对操作维护管理系统的功能要求，设计并实现了面向分布式路由器的操作维护管理系统。最后总结了全文并指出了进一步研究方向。

DESIGN AND IMPLEMENTATIONOF THE OPERATING AND MAINTENANCE SYSTEM IN DISTRIBUTED ROUTER

The OAM(Operating and Maintenance) module of a router should implement the management and manipulation of the router. The OAM is one of the most important sub systems in a router, guaranteeing it to work in going order. High performance multi protocol router often uses distributed architecture, and requires more efficient OAM. In this paper, the author makes a thorough research on router operating and maintenance system. First the OAM designed requirements and evolutions are introduced. Then the author presents the high performance multi protocol router architecture and OAM function requirements, which is developed by Tsinghua University, and designs and implements the router operating and maintenance system for distributed architecture in detail. At last, research directions and open problems in this area are discussed.
