Paper Abstract

To support diverse transmission requirements of multimedia applications, Quality of Service (QoS) should be provided in the Internet, where only the best-effort service is available. Based on the bandwidth broker model for realizing the IETF differentiated service (DiffServ), in this paper, we describe our recent effort on the implementation and verification of an extendable and flexible QoS allocation and resource management system. Focusing on the bandwidth issue over single administrative domain, the implemented system provides real-time resource reservation and allocation, delayed call admission control, simple QoS negotiation between server and user, and simple resource monitoring. The implemented system is verified by evaluating the performance of a resource-intensive application over the real-world testbed network.
