  • Performance improvement of ABT protocols with combined bandwidth/buffer reservation

    Publication Year: 1998, Page(s):129 - 136
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (676 KB)

    ABT (ATM block transfer) is expected for effectively transferring highly bursty data traffic in ATM networks. In the past work, ABT/IT has been shown to be robust in that its performance is not much affected by the propagation delay when compared with ABT/DT. However, when the traffic load becomes heavy and/or when the number of hop counts of the connection becomes large, the throughput of ABT/IT ... View full abstract»

    SuperPONs are access systems based on optical tree infrastructure. They are an extension of APONs (ATM-based passive optical networks), from which they differ mostly by their size. This paper considers the applicability of APON medium access protocols in the SuperPON context. More specifically, a modified version of the APON protocol proposed in Stojanovski and Gagnaire (1997, 1998) is considered.... View full abstract»

    Output contention resolution is a fundamental issue of ATM switch design. Output contention is much more severe in multicasting compared to the unicast counterpart. Previous studies have found that the cell loss probability of multicasting is slightly lower than unicasting. That is mainly because the effective cell arrival rate is reduced when the output load is kept unchanged. The performance of ... View full abstract»

    We show that by adjusting the rate decrease factor (RDF) and the rate increase factor (RIF) of the switches in an explicit forward congestion indication (EFCI) ATM network, we are better able to implement available bit rate (ABR) services via improved flow and congestion control. First, we find that adjusting the RDF while keeping the RIF constant reduces the amount of time a network remains in a ... View full abstract»

    Publication Year: 1998, Page(s):378 - 384
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (532 KB)

    This paper is concerned with the queue length distribution at the output of an ATM multiplexer. More specifically, we derive an upper bound on the complementary queue-length distribution for a multiplex of several pre-aggregated cell streams arising from a multiplex of constant bit rate (CBR) cell streams. An upper bound on the second-stage complementary queuelength distribution is useful when siz... View full abstract»

    We consider an asynchronous transfer mode (ATM) adaptation layer 2 (AAL2) system similar to that described by Baldwin, Bharucha, Doshi, Dravida and Nanda (see Bell Labs Technical Journal, vol.2, no.2, p.111-31, 1997), but with the additional possibility of selectively dropping the less significant bits of voice packets during periods of congestion. Dropping less significant bits of voice for relie... View full abstract»

    The provision of bandwidth-on-demand with quality-of-service (QoS) guarantees has long been a promise of ATM networks. However existing traffic management services provide only static traffic contracts bound to network-level QoS measured in terms of traffic engineering parameters. These parameters do not convey application-specific needs. As a result, the network does not consider the sensitivity ... View full abstract»

    Classical control theory is proposed to give a general framework for designing congestion control algorithms for ABR service in ATM networks. The algorithm is entirely implemented at the source whereas the switches in the network are in charge of supplying the feedback. Switches feed back to the ABR sources both queue level and available bandwidth. The queue level is fed back to track a queue thre... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (452 KB)

    Conventional negative feedback schemes have overall network congestion collapse problems when returning resource management cells experience extreme congestion. These schemes use an interval-based approach, which increases the complexity of implementation and often becomes expensive. To resolve these problems without network performance degradation, an adaptive negative feedback congestion avoidan... View full abstract»

    Earliest deadline first (EDF) schedulers are known to be optimal with respect to achieving delay bounds in the single node case. For a session traversing a multi-node network, applying EDF schedulability condition at each node separately leads to very restrictive admission control policy for delay sensitive applications. Other scheduling disciplines such as PGPS, that take into account the delay d... View full abstract»

    This paper presents a general integer programming formulation for the capacity and flow assignment problem in self-healing ATM VP networks with path restoration. It is observed that using group VP concept can substantially reduce the restoration time with only a small increase in spare capacity cost. The economy of scale in transmission facility cost is illustrated via numerical examples View full abstract»

    An efficient approximation for finding loss in high speed networks is proposed. We use an infinite buffer model to derive an upper bound on the performance of finite buffer models. We also use a large buffer approximation and Markov modulated fluid (MMF) models to represent the sources. We approximate loss by the product of an overflow probability and a conditional expectation of the instantaneous... View full abstract»

    TCP/IP based data communication is one of the most promising applications in wide area ATM services. However, it is noticed that TCP becomes the throughput bottleneck over an international ATM network with large propagation delay. The major reason for this problem is that TCP performs window based flow control and the maximum value of the window size is limited by 64 kbytes. Against this problem, ... View full abstract»
