A B-ISDN/ATM traffic descriptor, and its use in traffic and congestion controls

The authors summarize issues underlying the need for a traffic descriptor methodology for B-ISDN/ATM (broadband integrated services digital network/asynchronous transfer mode), and they identify objectives to drive the selection of an appropriate traffic descriptor. Two of these objectives are that the traffic descriptor should relay strongly to (i) B-ISDN/ATM call admission control (CAC) and (ii) B-ISDN/ATM usage parameter control (UPC). A traffic descriptor related to traffic peakedness is investigated and shown to have considerable promise with regard to these two objectives.<
