Analysis of Information Model of Optical Transport Networks

根据CIM的思想 ,提出了OTN的一种信息模型 ,用于企业级的网管开发。其中 ,逻辑单元的对象定义满足对被管理对象的一致性要求 ,这是系统互连互通的一个前提。物理单元的对象定义能够实现对物理设备的分级化管理 ,并且可以根据要求实现故障定位到单板或端口。此外 ,给出了本信息模型用于 863计划“中国高速信息示范网”项目中 ,被管理对象之间的关系的一个示例。

Based on common information model (CIM), this paper presents an information model for optical transport networks (OTN) in developing network management systems on a project level. The object definitions of logical elements satisfy the consistency requirements for managed objects, which establish a premise for interconnection and interworking between different administrative domains. The object definitions of physical elements provide a method to manage the OTN equipments effectively in a hierarchical structure. The requirement for fault localization to board or port can be covered with this information model. This information model is used in the 863 'CAINONET' project of China.
