IP网络计费管理研究

Research on IP Network Accounting Management

1.引言 在计算机网络管理范畴,计费这项应用曾经是五大网络管理应用中受到关注最少的一项应用[1,2],很大程度上是受Internet的研究性质影响.而电信网则不同,计费是首要考虑的应用.随着Internet的商业气息越来越浓,计费受重视程度也越来越高[3],网络计费相对其他网络管理应用较为独立.

Accounting Management is probably the least developed IP network management application. Now it is paid more attention than before. Accounting is relatively a unattached and typical application compare to other IP network management applications. First , the non-technical factors are described. And then, the accounting objects and accounting policy are researched and described formally. The CORBA-based accounting architecture is presented. The architecture has three layers. First layer is the Web interface used as the users' interface. Java Applet is used to pass some active data. HTTP Server and CORBAAcct Server locate in the second layer. The database server is also located in this layer. The CORBAAcct Server defined by some CORBA objects accomplishes the accounting. The third layer is the device Agent on which the raw accounting data are introduced. The client communicates with the CORBAAcct Server by IIOP and the communication between CORBAAcct Server and device Agent is based on network management protocol
