Patent ID: 8194568

Claim:
A method of monitoring blocked traffic in a telecommunications network including a plurality of switches interconnected by a plurality of trunk groups, said method comprising the steps of: collecting respective switch data from each of said switches including respective routing tables and trunk performance parameters for a current time period; identifying final trunk groups for each respective switch in response to said respective routing tables; determining a number of circuits within each final trunk group; determining total usage of each of said final trunk groups in response to said respective trunk performance parameters; determining a blocking value for each of said final trunk groups; generating a network portrayal wherein each of said switches is depicted by a respective graphic element having a respective non-alphanumeric characteristic for identifying one of a plurality of ranges of aggregate blocking values for each respective switch; storing a history of said blocking values; generating a plurality of switch portrayals wherein each switch portrayal depicts each final trunk group within a respective switch by a respective graphic element having a respective non-alphanumeric characteristic for identifying a respective one of a plurality of ranges of blocking values; displaying the network portrayal and switch portrayals on a display screen, wherein said portrayals represent a time period having a worst grade of service within a predetermined time span; and generating a worst trunk group portrayal listing a plurality of final trunk groups having a highest blocking percentage of all final trunk groups during said predetermined time span.
