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.
