چکیده
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 LAN–ATM 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. q 1999 Elsevier Science B.V. All rights reserved.

A new distributed routing algorithm for supporting delay-sensitive applications
We propose a new distributed delay-constrained unicast routing algorithm which can always nd a delay-constrained path with small message complexity if such a path exists. At each network node, limited information about the network state is needed and only a small amount of computation is required. Simulation results show that the proposed algorithm has much better cost performance than the leas...

In this paper, the requirements of routing due to the multimedia applications are briefly discussed. In order to solve the QoS constrained routing effectively and efficiently, the scheme of routing based on a genetic algorithm (GA) is proposed after the analysis of related works. Then the QoS routing algorithms for unicast and multicast based on improved GA are described. Finally, the results o...
