QoS Management in a Continuous Media Network System

In this paper, we describe the design and implementation of a suite of network protocols on a real time operating system that ensures the QoS (Quality of Service) of continuous media applications. The suite consists of a newly designed transport layer, a network layer that includes ST-II, a reservation-based network protocol, and a data link layer providing network access to ATM and Ethernet interfaces. Working together, these protocols manage QoS dynamically and o ers a exible way to utilize network resources. Furthermore, since this new network architecture follows a layered approach, it can adapt easily to di erent types of networking environments.
