Abstract
A paradigm shift is underway in how computer networks are used. The new breed of applications that incorporate multimedia add a new dimension of complexity to network management because their service requirements are quite different from those of older applications. The problem lies in the service discipline of the network, where routers generally use a single queue which operates in a first-come-first-served manner. As traffic through the router increases, packet delays become longer to the point where the router's internal queue overflows and packets are dropped. This project addresses the design of a packet-switched network that can support soft real-time applications such as multimedia. We focus on the communications protocol, the router design, and the resource reservation and admission control policies that will allow the overall system to operate. We provide a survey of related work on design issues concerning network service paradigms, traffic policing mechanisms, resource administration mechanisms, and resource reservation protocols. We then discuss the design and implementation of our router, end-systems, and admission control policies. We show that with the proper choice of protocols, traffic policing, and resource reservation within the router, a packet-switched network can support guaranteed quality-of-service for multimedia communications.
