s, and relational databases. Protocols supported for interaction with network elements include TL1, SNMP, CORBA, XML-based messaging, and JMS. In addition to Web servers like Java Web server and Apache Tomcat, Web-based publishing to northbound interface is facilitated using application servers like JBoss and Weblogic. From a database perspective, AdventNet provides data integration with Oracle, Sybase, Mysql, MS Sql, Solid, Timesten, and many other popular databases. Multiple service providers have adopted AdventNet for unified management of its networks. This would involve AdventNet collecting data from elements of multiple networks and representing it in a common GUI. Centralized configura- tion of devices and quick launch of element managers is also possible. Distributed mediation servers is a remote management feature of Adventl in which multiple mediation servers collect data from elements in the network and forward the data to a centralized server. Some of the functionalities in AdventNe Web NMS are: Fault management: The usual capabilities provided in NMS for alarm moni- toring, like filtering a particular alarm, suppression of alarms that are not of interest for user and correlating alarms is performed. Segregation of alarms based on severity and the element where the alarm originated can be per- formed from AdventNet Web GUI. Clearing and acknowledging an alarm is also supported. Configuration management: Network elements are automatically discovered and their topology is created. An audit is performed on the discovered ele- ments and their attributes, to get status updates that are not propagated with asynchronous notifications from the devices. Inventory management capabil- ity is also in AdventNet with information on all devices in the network. Performance management: The performance data collected from the network are aggregated and analyzed to generated graphical reports in AdventNet Web GUI. The functionality of filtering helps to customize performance reports. Thresholding is also supported and A
