提出了一种基于 CORBA的分布式 SDH网络管理结构 ,其中 ,引擎的概念在分布式异构环境下继承和发展了 SMN的分层管理思想和组织模型 ,由它所构成的引擎组在 CORBA服务和扩展服务支持下 ,能很好地完成 SMN的各层管理功能 .新的网络管理结构还提供了网关模块 ,以实现与采用 CMIP协议或 SNMP协议的 SMN系统互连 This paper proposes a distributed SDH network management architecture based on CORBA, in which the concept of engine inherits and develops the hierarchical management idea and organization model of SMN under the distributed heterogeneous environment. The engine group formed by it inherits and develops in the CORBA service And extended service support, and can well complete all layers of SMN management functions.The new network management structure also provides a gateway module, in order to achieve with CMIP protocol or SNMP protocol SMN system interconnection
