Abstract
This paper presents a new RTM (real-time traffic management) scheme th at can effectively manage VBR (variable bit rate) traffic having unpre dictable characteristics in ATM (asynchronous transfer mode) networks. In addition to its precise cell control capability, the proposed sche me intends to efficiently use the resources of high-speed, high-perfor mance broadband networks without any deterioration in QoS (quality of service) of the accepted connections. Specifically, this paper highlig hts some functions of bandwidth management and connection admission co ntrol that should be integrated to operate correctly in the emerging A TM networks. A unique feature of this scheme is that it reports the re sults of traffic monitoring, which makes it possible to control VBR tr affic in real-time so that the delay incurred to measure cell arrival rate in existing algorithms is removed. This property makes the scheme extremely attractive for supporting most delay-sensitive applications . Using simulations, the proposed RTM scheme has been verified to reli ably monitor incoming traffic, manage virtual connections, and reassig n resources efficiently.
