“…In [2,6] we show that with end-to-end based controls, VC's traversing two or more hops can see a throughput collapse at high loads. To overcome the unfair advantage that VC's traversing small number of hops have over VC's traversing larger number of hops, we proposed an access priority mechanism where transit traffic from upstream switches are given priority of service over new traffic entering the network at each switch.…”

An adaptive end-to-end rate based congestion control scheme to support a class of best effort service known as Available Bit Rate Service (ABR) is being proposed by the ATM Forum. In this paper we present the implementation of two variants of this control scheme. In the first scheme known as the Explicit Forward Congestion Indication (EFCI) scheme, a single bit is used to convey to the source the state of the network. In the second scheme, known as the Explicit Rate (ER) scheme, the network informs the sources from time to time, the maximum rate at which they can transmit. We investigate the transient performance of the two controls in the presence of high priority cross traffic. The EFCI mechanism is fundamentally oscillatory in nature and can lead to large cell loss. The ER scheme is very stable, even under extreme loading conditions, with good transient response.

“…These assumptions may not be consistent with real network situations. Some other binary feedback rate-based congestion methods are proposed in [6], [21], [13], [15]. However, in these binary feedback schemes, the ABR traffic must converge gradually to the available bandwidth, whereas ER feedback allows the ABR traffic to immediately utilize available bandwidth.…”

This paper addresses the design and analysis of an end-to-end rate-based feedback flow control algorithm motivated by the available bit rate (ABR) service in wide-area asynchronous transfer mode (ATM) networks. Recognizing that the explicit feedback rate at time will not affect the ABR buffer until time + for some 0, our approach is to first predict the ABR buffer status at time + , then base fuzzy-logic rate control decisions on these predicted values, and finally tune the controller parameters using gradient descent methods. Simulations show that this predictive self-tuning fuzzy-logic (PSTF) control scheme is efficient, stable, and outperforms other proposed ABR rate controllers in a variety of network environments. With delays corresponding to a U.S. coast-to-coast connection, the PSTF controller can maintain high link utilization, avoid buffer overflows, and provide fair allocation of resources.Rose Qingyang Hu (S'95-M'98) received the B.

The broadband integrated services digital networks are based on the ATM technology. As these networks will be deployed gradually, the existing high-speed data services, as Frame Relay and SMDS, will continue to exist and, for interoperability purposes, they will also be supported by the ATM networks. Moreover, ATM networks allows to efficiently support a new service, called available bit rate (ABR) service in the A TM Forum, which requires no bandwidth reservation. When this service is requested, data are transmitted through the network with low priority, being the available network resources shaped dynamically among all the active sources. In this paper, we first discuss how to manage FR and SMDS services in the ATM networks, and report the performance evaluation of the proposed interconnection scenarios; then, we present some preliminary simulation results on the ABR service, whose implementation needs a sophisticated reactive congestion control to obtain an acceptable quality of service.
