A dynamic bandwidth allocation rule for connection oriented DQDB-ATM and integrated services support

Metropolitan area networks are seen as backbones to local area networks interconnection. This will provide high speed integrated services to the user. We will briefly discuss the connection-oriented DQDB architecture, its internetworking with ATM, and the support of integrated services. We introduce the “sensitivity” of a connection, and show how it affects the required capacity with changing rates. We propose, QoS management layer (as a part of the management plane), in the connection-oriented DQDB which is responsible for mapping the QoS requirements and allocating resources dynamically. This is very attractive, particularly for “integrated-services” support
