Abstract

Quality of service (QoS) in Layer 3 is essential for satisfying various types of Internet-application requirements by making the best use of limited bandwidth. A large number of such applications still use TCP/IP in order to connect various types of computer nodes. This paper investigates QoS performance in a network equipment testbed. We examine the major class of service (CoS) functions provided by the Juniper T320 router, and measure their performance. In addition to fundamental analysis of the QoS behavior, we show the impact of QoS operations on a parallel system distributed in multi-domain networks as a practical case study of grid environments.
