一种SDH网络层管理系统框架的研究

The Research on Framework of SDH Network Management System

目前的网络层网管系统大都从单元层网管演化而来,其结构的局限性给网络层网管的性能和扩展性带来了影响。本文基于 TMF 模型,提出一种 SDH 网络层管理系统的系统框架,以资源管理为核心,采用被广泛支持的 TMF513 接口。在资源管理层,为满足网络层对业务管理的需要,将子网连接管理独立出来,重点描述子网连接管理需要完成的功能,并通过一个用例,描述框架内部以及与接口的交互。

Most of network layer management system is evolved from unit network management. The limitation of this architecture influents the performance and expandability of network layer NMT. The paper provides a SDH NMS framework based on TMF model. This model uses the popular TMF513 Interface and concentrate resource management. At the resource management layer, the sub-network connection management is independent for the need of business management. The function of sub-network connection management is described, and a use case to describe the internal of this framework and the interaction of interface is given.
