A METHOD OF AUTOMATICALLY CONTROLLING PERFORMANCE MEASUREMENTS IN A NETWORK, A PERFORMANCE MANAGEMENT CONTROLLER, AND A PERFORMANCE MANAGEMENT SYSTEM

摘要

A network management system (1), for example for use in a telecommunications network (7), comprises a performance management tool (3) for carrying out a plurality of performance measurements (5) relating to physical or logical components of the network (7). A fault management tool (9) provides fault reports (11) relating to faults detected in the network (7). A configuration management tool (13) controls the configuration of the network (7), and provides configuration reports (15) on changes to the network configuration. A performance management controller (17) comprises a control unit (25), a list of performance measurement groups (19), a list of logical/physical components in the network (21) and a list of predefined time schedules (23). Upon receiving network configuration information (11, 15) from either the fault management tool (9) or configuration management tool (15), the control unit (25) determines whether any network performance measurements need to be changed, and if so, automatically changes them accordingly. In this way, the system is able to adaptively change the performance measurements in response to actual changes in network configuration, thereby ensuring that the most appropriate measurements are carried out.
