 interface for this database might be implemented using a package such as MapX ActiveX Geoinformation System Component from MapInfo. Accounting management agents are responsible for accurate collection and processing of accounting records, maintaining billing policy and updating tariff information. Security management agents are responsible for corporate immunity against corruption and intrusion. Security management agents monitor different security- related events and generate alerts which may be regarded as of very high priority, certainly comparable with fault management alerts. The WBEM-enhanced Mold-TMS is under testing, having implemented many types of agent and an integrated software system at its National Telecommunication Control Center, a national NOC. 14.2.3 Conclusions from Case Study The practical implementation of a national-level TMS using WBEM technology demonstrated the efficiency of the architecture and system design. Using a browser such as Internet Explorer with a reduced number of ActiveX components and HTML-speaking agents at the server sides, it is possible to generate sufficiently sophis- ticated scaleable control and monitoring schemes for distributed object manage- ment over a pan-national telecom system. OSS for Telecom Networks The Moldovan project was groundbreaking at the dawn of the twenty-first cen- tury and is still a rare example of how a national telecom network might be run in an entirely centralised way. We now turn to a more advanced approach to the prob- lem of developing a distributed environment for web-based network management. 14.3 Developing a Distributed Environment for Web-based Network Management This section is based on the work of Flavio Spolidoro of Empresa Brasileira de Telecomunicacoes and Noemi Rodriguez of the Departamento de Informatica, PUC-Rio, Brazil.5² The use of scaleable management tools is becoming more important for integrated management of different network platforms, and a flexible environment for web-based distributed network management would be a
