We propose a receiver-oriented resource reservation mechanism, called dynamic management of QoS with priority (DMQP), for multimedia multicasting over the internet that provides quality of service (QoS) guarantees with service differentiation for heterogeneous users. In the DMQP protocol, a real-time application requests QoS by specifying a range of acceptable bandwidth values and tolerable delay durations as opposed to rigid QoS criteria. The network strives to reserve resources for the application within its bandwidth range. The service differentiation is achieved by classifying the realtime applications (or end-users) into normal and prioritised users. When the number of end-users increases, all nodes, including the receiver, sender and intermediate nodes, readjust their reserved resources dynamically to admit the new end-users, as long as their minimum bandwidth requirement is met. The DMQP provides the flexibility needed for operation in the dynamic internet environment. It has significant benefit of allowing more flexible sharing of available resources among applications.
