Abstract

Guarantees of services in a networked environment are providedby the proper allocation and scheduling of network and system resources. A lot of research in packet scheduling, QoS routing,traffic multiplexing, etc. has been aimed atproviding deterministic or statistical service guarantees, while utilizing resources efficiently.In this paper, we propose a resource reservation scheme for a class ofmultimedia presentations. We characterize this class of multimedia presentationsas synchronized distributed multimedia sessions, which webelieve are important components of many multimedia applications.In addition to multimedia presentations, the reservationscheme applies to applications with synchronizedresource requirements. Based on resource inquiry and interval analysis,the scheme is also able to find feasible resource allocation schedulesfor resource reservation requests.Built upon a layer of resource abstraction, the schemesuits well with today‘s heterogeneous network environment.
