    With the explosive growth and pervasive reach of the Internet, it is becoming the de facto standard user network interface. The vast majority of new networking applications assume this interface. Consequently, ATM technology is increasingly used to carry IP datagrams. So far however, the control and signaling model of ATM has not been adequately optimized for this use. Moreover, the incompatibilit... View full abstract»

    Several multimedia applications like video-conferencing and distributed interactive simulations require efficient support for multipoint-to-multipoint connections from the underlying networks. The routing and signaling protocols for supporting these connections in ATM networks have been proposed earlier by Venkateswaran et al. (see IEEE ATM'97 Workshop, p.263-71, 1997). In this paper, we address t... 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»

  • An ABR congestion control algorithm feeding back available bandwidth and queue level

    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»

    There are several issues to be resolved when the legacy ATM switch is applied as a forwarding engine for the label switching router (LSR). They are mostly due to inconsistency between the requirements for the current and future Internet and capabilities of most of legacy ATM switches. This paper clarifies issues in constituting ATM-based LSR (ATM-LSR) networks as the Internet backbone, label resou... View full abstract»

    This paper presents a dynamic virtual path (VP) survivability admission control mechanism for survivable ATM networks. This scheme integrates the dynamics of demand admission and logical spare capacity assignment for maximizing network resource utilization ratio while ensuring full traffic restorability under any single link failure scenario. The simulation results show that this mechanism is very... View full abstract»

    Today, ATM networks are being used to carry bursty data traffic with large and highly variable transmission rates, and burst sizes ranging from kilobytes to megabytes. Obtaining good statistical multiplexing performance for this kind of traffic requires much larger buffers than are needed for more predictable applications or for bursty data applications with more limited burst transmission rates. ...

    This paper proposes new scheduling mechanisms for meeting fairness criteria which are not met by conventional scheduling mechanisms such as weighted round robin (WRR). These proposed mechanisms utilize the arrival of untagged cells at an ATM switch not only for a frame drop policy but also for deciding which VC cell is eligible to be serviced. The guaranteed frame rate (GFR) service using the prop... View full abstract»

    A rate-based congestion control algorithm is a feedback-based flow control mechanism for ABR (available bit rate) service class, which is suitable for data transfer applications. The rate-based congestion control algorithm dynamically regulates a cell transmission rate of a source end system according to feedback information from the network. An appropriate choice of control parameters can lead to... View full abstract»

    We continue our previous work on switch-aided flooding (SAF) for use in ATM networks. The SAF-based protocols take advantage of hardware-supported cell relay and cell duplication in order to reduce the time needed to disseminate changes in network topology and resource availability. The SAF protocols use a spanning multipoint connection (SMC), which is a hardware-switched network spanning tree, bu... View full abstract»

    This paper addresses the problem of determining the change in the leaky bucket (LB) based characterization of a guaranteed service flow as it traverses an ATM subnet in an IP-ATM internetwork. The LB-characterization of the flow changes at the ATM network boundaries since overhead is added/removed and delay is introduced due to the mapping between IP packets and ATM cells. We obtained analytical r... View full abstract»

    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»

    Variable bit rate video (VBR) allows statistical multiplexing in asynchronous transfer mode networks (ATM) while offering constant visual quality. A key issue for achieving efficient video multiplexing and therefore efficient admission control is the selection of a VBR video characterization specifying accurately the rate distribution of video sources. We show that the gamma distribution is a good... 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»

    A new ATM adaptation layer (AAL2) to support low bit rate and delay sensitive applications in an ATM environment has been approved by ITU-T. AAL2 allows multiplexing of voice/data packets (minicells) from different users in a single ATM connection thus improving the utilization of the network resources. This paper identifies issues related to AAL2 such as the application environment, the gain obta... 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»

    The balanced gamma network is a fault tolerant multistage interconnection network. In a previous paper, the reliability of the balanced gamma network was studied. The terminal reliability, broadcast reliability, and the network reliability were evaluated. However, the previously provided network reliability model was approximated.

    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»

    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»

    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»
