Adaptive proportional rate control for ABR service in ATM networks

The emergence of asynchronous transfer mode (ATM) technology has generated new challenging problems for computer network designers. One of these challenges lies in the efficient management of ATM traffic so that the communication bandwidth of the network can be optimally utilized. Considerable standardisation efforts in recent ATM Forum activities have been centered on the traffic management of available bit rate (ABR) service. In this paper, we examine congestion control schemes for ABR service in ATM networks. We propose a rate-based scheme that is now referred to by the ATM Forum as `intelligent congestion control´ or `intelligent marking´. This general rate-based framework has been adopted as the standard approach to congestion control for ABR service by the ATM Forum. Moreover, we present analytical and simulation results illustrating the characteristics of the proposed scheme
