Abstract
The inventive mechanism monitors ATM traffic load by service type. The inventive mechanism receives each cell being transported over a backbone or link of an ATM network. The mechanism creates a table, which includes the VPI/VCI tags and the respective service type for each tag, to determine the numbers of cells being transported for each of the service types. The mechanism forms the table by monitoring connection/call setup-request cells and their associated answer cells, which identify the service type for each VPI/VCI tag. The inventive mechanism may set alarm levels to trigger based upon the pipe bandwidth usage by the different service types.
