Patent ID: 8396000

Claim:
A non-transitory computer readable storage medium including a set of instructions executable by a processor, the set of instructions, when executed by the processor, causing the processor to perform a method comprising: receiving an image of a switch in a communications network, the image being a representation of internal hardware and software of the switch; simulating a plurality of communication sessions using the image; generating a plurality of simulated communication session records corresponding to the plurality of simulated communication sessions; and evaluating a performance of the switch by comparing the plurality of simulated communication session records to a set of expected communication session records, the expected set of communication set of records corresponding to the set of simulated communication sessions, identifying an error group of the simulation communication records that do not match the set of expected communication records, determining a percentage of the simulated communication records that do not match the set of expected communication records, comparing the percentage to a threshold percentage, and evaluating the error group for false negatives, if the percentage is greater than the threshold percentage.
