Service quality in operational IP networks can be impacted due to planned or unplanned maintenance. During any maintenance activity, the responsibility of the operations team is to complete the work order and perform a check-up to ensure there are no unexpected service disruptions. Once the maintenance is complete, it is crucial to continuously monitor the network and look for any performance impacts. What operations lack today are effective tools to rapidly detect maintenance induced performance changes. The large scale and heterogeneity of network elements and performance metrics makes the problem extremely challenging.
