面向异构网管理的多级中间件体系

Heterogeneous Networks Management-Oriented Architecture for Multi-layer Middleware

为了减少异构网网络管理方面所付出的代价,继续利用各专业子网已有的网络基础设施并对其进行跨域管理,提出了一种多级网络管理体系。该体系模型以面向对象、中间件技术为核心,利用CORBA的IDL接口封装网元层元素,将本地各专业子网抽象为分布式对象,使用CORBA平台完成对象间的互连,中间层使用CORBA/WEBSERVICES复合代理,上层则由WEBSERVICES直接联入INTERNET。授权用户可在INTERNET任意一点应用GUI终端(浏览器)访问网络系统,对异构网下层网元元素进行网络管理。

In order to reduce the cost of heterogeneous networks management and use current basic foundation, this paper shows a new model of the architecture of multi-layer networks management, designed for working in heterogeneous networks. The model proposes a new technologic choice to those existing in the scope of distributed middle-ware and object-oriented technology. It is mainly implemented with CORBA and Web Services components. Net ceils of special child-networks are enveloped using CORBA IDL interface. The communications between special child-networks as dis- tributed objects are under CORBA environment, following the middle layer of applying CORBA/Web Services compound agent that user interface components provide service to each other. Network management application （GUI） on the design for accessing distributed networks. Based on the fact that heterogeneous networks can be managed.
