    Publication Year: 1999, Page(s):385 - 390
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (412 KB)

    This paper proposes input buffering of controllable traffic as a simple and effective solution for congestion control in ATM WANs. ERICA and adaptive stochastic (AS) flow control schemes are used for comparing two network configurations: network “A”-where feedback messages travel to each individual source and network “B”-where feedback messages are sent from the output port...

    In asynchronous transfer mode (ATM) networks, to avoid congestion situations which decrease the quality of service (QoS) of already established connections, usage parameter control (UPC) is necessary. An ideal UPC mechanism must be able to detect any possible violation from the traffic contract. In this paper we use the benefits of fuzzy logic to design a high performance fuzzy traffic controller.... View full abstract»

  • Combining CAPC and weighted traffic scheduling to achieve high quality ABR traffic control

    Publication Year: 1999, Page(s):187 - 192
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (268 KB)

    The classical method of max-min fair-rate allocation doesn't support the weighted-rate guarantee. The weighted-rate guarantee is necessary to available-bit rate (ABR) service models. This fact has motivated the wide study of weighted max-min (WMM) fair-fate allocation for ABR traffic. However, the combination of close-loop feedback control with the WMM algorithm has not appeared in the previous re... View full abstract»

  • Multicast ATM switch architecture based on a recursive method

    Publication Year: 1999, Page(s):475 - 480
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (392 KB)

    This paper proposes simple architecture to support multicasting in ATM switches. The proposed architecture consists of a self-routing switch which enables us to copy cell and line interfaces with a header conversion part. Our finding is that multicast can be realized by the method as follows; (1) copying cells in the switch; (2) recurring the copied cells from output ports to input ports; (3) chan...

    Cited by:  Papers (4)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (364 KB)

    Recently, a novel quasi-static routing scheme called path switching has been proposed for a large-scale ATM packet switch, and a Clos-like switching network called the cross-path switch was designed for its implementation. In principle, the cross-path switch can support both multicast and multirate traffic and now we add the capacity of supporting multimedia traffic in it. In this paper, we develo...

  • Cell selection algorithm for the multiple input-queued ATM switch: chessboard and random cell selections

    Publication Year: 1999, Page(s):259 - 264
    Cited by:  Papers (2)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (460 KB)

    A simple and efficient cell selection algorithm for the multiple input-queued ATM switch, named the chessboard cell selection algorithm, is proposed in this paper. The proposed algorithm selects one of the transmission requests for the output port with the lowest value of transmission request sum. By doing so, we can reduce a newly introduced front-of-line (FOL) blocking so as to achieve an enhanc... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (488 KB)

    The fair distribution of bandwidth to different connections is an important issue in high-speed networks. This is especially true in low-priority services where the bandwidth available for the low priority connections may be small and may vary rapidly. An example is the available bit rate (ABR) service in asynchronous transfer mode (ATM) networks. This study uses the ABR service to explore a schem... View full abstract»

  • An efficient admission criterion of traffic-shaped rate monotonic scheduler for VBR traffic

    Publication Year: 1999, Page(s):19 - 24
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (348 KB)

    The rate monotonic algorithm has recently been proposed to be used along with traffic shapers to provide quality of service guarantees in ATM networks. A necessary and sufficient condition for admission control has been derived assuming that cell arrivals are periodic (i.e., CBR traffic). For bursty traffic, this criterion is obviously conservative and may significantly reduce bandwidth utilizatio... View full abstract»

  • New automatic error control system with ATM cell header reduction for wireless ATM networks

    Publication Year: 1999, Page(s):233 - 238
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (420 KB)

    In this paper we introduce a new error control system for wireless asynchronous transfer mode (WATM) networks. The new system is based on using a new scheme to reduce the ATM cell header size before applying the multiple error correcting Bose-Chaudhuri-Hocqenghem (BCH) code instead of the usual header error control (HEC) for the wireless portion of the transmission. This new scheme implies dividin... View full abstract»

  • Emulation of an output queued switch with a combined input output queued switch

    Publication Year: 1999, Page(s):463 - 468
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (392 KB)

    The combined input output queued (CIOQ) architecture such as crossbar fabrics with speedup has recently been proposed to build a large-capacity switch for future broadband integrated services networks. Unlike an output queued (OQ) switch where queueing happens only at output ports, it is much more difficult for a CIOQ switch to provide quality of service (QoS) guarantee. Obviously, to achieve good... View full abstract»

  • Prioritized arbitration for input-queued switches with 100% throughput

    Publication Year: 1999, Page(s):253 - 258
    Cited by:  Papers (7)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (516 KB)

    Input buffered switches are known to suffer from head-of-line (HOL) blocking that limits the throughput to approximately 58.6%. It has been shown that 100% throughput can be achieved with virtual output queueing (VOQ) and an arbitration algorithm that controls the access to the switch fabric in each time slot. No weight-dependent algorithm was known that supports priorities, which are necessary fo... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (324 KB)

    In this paper, we propose a new network protocol framework, the adaptive mobile network protocol (AMNP) for general mobile networks based on the idea behind the hybrid IP/ATM. In AMNP, two operation modes are defined for each network layer packet present at a mobile network node, namely, the connection mode and the connectionless mode. The modes are inter-changeable depending on the mobility of th... View full abstract»
