Abstract :
A traffic control architectural framework for broadband integrated services digital network asynchronous transfer mode (B-ISDN/ATM) is outlined. Network congestion control procedures are devised, complemented by specific end-terminal controls. The network congestion control system is partitioned into three domains: network-element internal, networkwide, and call-level controls. A selective discard mechanism based on traffic tagging and monitoring via both a rate enforcement module and a selective discard module is proposed, along with a set of preventive, protective-reactive, adaptive-reactive, and adaptive-reactive-supportive mechanisms. The need for a traffic descriptor, either statistical or operational, logically related to both call admission control and usage parameter control, is discussed.<>
