在基于CORBA/XML网络管理中IDL和XML数据的信息交互

Interchanging Method of IDL and XML Datum in Network Management Based on CORBA/XML

CORBA与XML结合的关键在于IDL格式和XML格式数据的交互。提出了一种基于WBEM体系结构的网络管理系统的客户端/服务器端模型,同时基于该客户端/服务器端模型提出了一种IDL和XML数据交互的方法并进行了实验实现,实验证明该方法可行。

The key that CORBA and XML combine lies in the data interchange of IDL and XML. Making reference of WBEM, this paper proposes a C/S management model based on CORBA/XML. The client is a browser based on XML/Schema, the browser can display network management according to the requirement depending on XSLT. The transport of this model is HTTP, which can pass firewall easily. Making use of the flexibility of XML, CORBA invocation and object information is embedded in a suitably structured XML document, which is called CORBA request requiring CORBA object service compared with HTTP request just require HTTP service. The treatment result of XML/Schema or converted CORBA/IDL is provided to client browser. Then, an approach of mappings XML/Schema and CORBA/IDL has been presented. Implementation program of interchanging of IDL and XML datum in a in network management based on CORBA/XML prototype are also discussed.
