    In this paper we propose a solution that integrates traffic shaping with fair queueing into a single scheduling algorithm. The proposed algorithm called “fair shaping mechanism” is used to manage bandwidth on ATM virtual channels in non real time network terminals. It takes into account the general expression of ATM traffic parameters. We discuss the necessary modifications of these pa... 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»

    We first study the mapping of the Integrated Services IP (ISIP) traffic descriptors to the ATM counterparts, for the MPEG2 video traces developed in our lab. We employ the direct method of mapping and compare it with the indirect methods reported in literature. Second, we investigate the effects of internetworking on the ATM traffic descriptors, where ATM is to form a link in the path of a point-t... View full abstract»

    The design of a practical ATM network continues to be challenging, owing to the difficulty in the accurate estimation of user traffic and the wide range of user's quality of service requirements. There is little consensus on the characterization of network performance, users' satisfaction, and the efficiency of network usage. This paper develops a single metric for network performance that capture... View full abstract»

    We study the performance of three switch implementations for the guaranteed frame rate (GFR) service category when used to provide a LAN interconnection service with a minimum guaranteed bandwidth. Our simulations show that the double-EPD implementation is sensitive to the maximum burst size (MBS) parameter of the GFR traffic contract, while an implementation based on weighted fair buffer allocati...

    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»

    The buffer management policy used at an IP/ATM gateway can significantly impact end-to-end performance for IP traffic (particularly apparent when IP traffic is transported using the ATM ABR service class). The ABR service is designed to achieve near-loss free operation in the core of the ATM network by adaptively shaping traffic at the edge of the ATM network. This can cause buffer build-ups to oc...

    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»

    The flexibility of ATM allows it to support various types of applications with diversified quality of service (QoS) requirements. We broadly classified these services into the delay sensitive (DS) class and the loss sensitive (LS) class. The scheduling problem for two priority classes is much more complex than the single priority class counterpart. The scheduling algorithm is required to satisfy t... View full abstract»

    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»

    ATM technology is facing challenges from integrated service IP, IP switching, gigabit IP router and gigabit Ethernet. Although ATM is approved by ITU-T as the standard technology in B-ISDN, its survivability is still in question. Since ATM-UBR (unspecified bit rate) provides no service guarantee and ATM-ABR (available bit rate) is still unattainable for most users, many existing users have little ... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (324 KB)

    This paper presents a novel technique for analyzing transient performance of cell streams at an ATM link. Transient performance analysis is important, since performance of a connection is in fact dominated by the transient behavior of the underlying traffic process. The previous work on transient performance analysis typically assumes that the traffic processes are Markovian. The novelty of the te... View full abstract»

    The point-to-multipoint ABR service within ATM is important for many emerging data applications. The objective is for the source to operate at a rate representing its max-min fair share over the bottleneck link in the multicast tree over which the connection is established. Resource management (RM) cells are used by receivers to convey back to the source an explicit rate indicating their bandwidth... View full abstract»

    In this paper we address the problem of call admission and resource reservation control in ATM networks, where customers can book their connections in advance. This is very likely to be a realistic situation for services where customers order a connection to be established some time later. The proposed framework can be used for the admission and resource reservation control for leased line service... 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»

    The ATM ABR traffic management entails that the source controlled to the minimum supported by all the leaves of the multicast. Since the amount of feedback (i.e., the number of backward resource management or BRM cells) received by the source is proportional to the number of leaves (destinations) in the multicast tree, it is necessary for the branch points to properly consolidate feedback to avoid...

    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»

    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»
