A Real-Time Integrated Traffic Management Scheme for VBR and ABR Services in ATM Switching Systems
Summary :
This paper presents a real-time integrated traffic management (RITM) scheme that can effectively manage variable bit rate (VBR) and available bit rate (ABR) traffics having unpredictable characteristics in asynchronous transfer mode (ATM) networks. An unique feature of this scheme is that it has a special ATM cell control block, which makes it possible to monitor VBR and bursty traffics in real-time so that the delay incurred to measure cell arrival rate is minimized. In addition to its traffic monitor capability, the proposed scheme intends to dynamically reassign the leftover network resources to VBR/ABR connections without any deterioration in quality of service (QoS) of the existing connections. Particularly, we investigate into some functions of traffic management schemes that should be integrated to operate correctly in the emerging ATM networks. Also, we emphasize the merits of the RITM that has been developed to be a simple and efficient traffic management scheme to support the increasing data/Internet services and to get over difficulties in hardware complexities. The capability of managing the incoming ATM traffics in real-time helps determine an optimal acceptable number of user connections for a given network condition. We can use this value as a threshold to prevent the network from being congested and to find out a cost-effective buffer design method. This property makes the scheme extremely attractive as it supports most delay-sensitive and loss-sensitive applications at the same time without changing the existing ATM switching system architecture. The RITM scheme has been verified to reliably monitor incoming traffics and to efficiently manage network resources by computer simulations.
