    In ATM networks, the Guaranteed Frame Rate (GFR) service has been proposed to accommodate non-real-time traffic with packet size not exceeding a maximum length, such as TCP/IP based traffic. The GFR service not only guarantees a minimum throughput at the frame level, but also supports a fair share of available resources. In this article, we propose a buffering strategy called Intelligent Fair Buffer Allocation (IFBA) that provides minimum cell rate (MCR) guarantees and fair sharing to GFR virtual circuits (VCs). From the simulation results, we demonstrate that IFBA fulfills the requirements of GFR service as well as improves the TCP throughput using the FIFO scheduling. (C) 2000 Elsevier Science B.V.

    It has been demonstrated that as the per-flow product of bandwidth delay increases, TCP becomes inefficient and unstable, regardless of the queuing discipline. By decoupling utilization control from fairness control, the eXplicit Control Protocol (XCP) outperforms TCP in both conventional and high bandwidth-delay environments. In this article,. we present an efficient flow control scheme based on XCP for high bandwidth-delay product networks. It can shorten the response time and improve the performance of XCP. Simulation results show the effectiveness of our proposed scheme in several performance aspects. Moreover, its implementation is simple enough to fulfill the required criteria of high bandwidth-delay product networks.
