Abstract
Available bit rate (ABR) is an emerging asynchronous transfer mode (ATM)-based telecommunication service, which dynamically
allocates bandwidth to the users according to the available bandwidth in the network. However, research shows that ABR-based connections
suffer from congestion at LAN­ATM gateway when ATM network abruptly reduces the bandwidth available to the gateway. Gateway
congestion may result in high packet loss. This paper proposes a gateway congestion control mechanism, which controls the rate of outgoing
enterprise traffic according to the available bandwidth at the gateway. Our analysis shows how to achieve a stable system and keep the packet
loss below a desired threshold. Analytical results are validated by simulation. 1999 Elsevier Science B.V. All rights reserved.
