    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...

  • Adaptive negative feedback congestion avoidance for ABR traffic in ATM networks

    Publication Year: 1998, Page(s):97 - 101

    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»

    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»

  • Transient performance of ATM cell streams

    Publication Year: 1998, Page(s):355 - 359
    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»

    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»

    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...

    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»

    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»

    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»

    Supporting guaranteed services in a large network requires solutions to many difficult problems. In this paper, we focus on the problem of on-demand routing of virtual circuits with quality of service guarantees. Specifically, we investigate the performance of the ATM private network-network interface (PNNI) protocol in a large topology with structure reflecting the hierarchy and locality present ...

    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»

    This paper develops an efficient buffer management scheme that makes generic ATM switches capable of supporting delay-sensitive as well as loss-sensitive traffic. The proposed scheme aims at enhancing the performance of ATM switches by maintaining the head cells of output queues in relatively short dedicated output buffers, while maintaining the long tails of overflowing queues in a shared-memory ...

    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»

    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»

    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. ...

    An architecture for ATM networks to provide more reliable transmission to support connectionless and multicast services for short message transmission is introduced in this paper. This architecture suggests to use a logical ring concept to form virtual legacy shared-medium networks in the ATM layer. With the use of ATM cell blocks and a Reed-Solomon code based cell-coding scheme in transmission, t... View full abstract»

    This paper proposes a high-speed connection admission control scheme, named PERB CAC (CAC based on prior estimation for residual bandwidth). This scheme estimates the residual bandwidth in advance by generating a series of virtual requests for connection. When an actual connection request occurs, PERB CAC can instantaneously judge if the required bandwidth is larger than the estimated residual ban... View full abstract»

  • Enhancing the end-to-end schedulability condition of EDF scheduling for real-time applications

    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»

    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»

    State (topology) aggregation is the notion of reducing nodal as well as link information to achieve scaling in a large network. In this paper, we compare the performance of three different aggregation schemes, namely, the simple-node scheme, the full-mesh scheme, and the star scheme, which represent a given group of nodes by a single logical node, a complete graph between border nodes, and a star-...
