Abstract:

Most application data units are too large to be carried in a single packet or cell and must be segmented for network delivery. To an application, the end-to-end delays and loss rate of its data units are much more relevant performance measures than ones specified for individual packets or cells. The concept of a burst or block was introduced to represent a sequence of packets or cells that carry an application data unit. In this paper, we describe how a real-time variable bit-rate VBR service, with quality of service QoS parameters for block transfer delay and block loss rate, can be provided by integrating concepts and delay guarantee results from our previous work on burst scheduling, together with ideas from asynchronous transfer mode ATM block transfer. Two new contributions are presented herein. First, we design an admission control algorithm to provide the following two classes of service bounded-delay block transfer with no loss, and bounded-delay block transfer at a specified block loss rate. Secondly, we show how to extend existing end-to-end delay bounds to networks with hierarchical link sharing.
