    On-line QoS routing in ATM networks involves challenging problems in the distribution of information and control. This paper presents a hierarchical routing architecture which adapts its own structure over time to match available bandwidth in the network. The adaptive hierarchy is shown to significantly outperform a similar static hierarchy in preliminary tests and comparisons with centralised and... View full abstract»

  • A performance-enhanced parallel scheduling algorithm for MIQ switches providing a QoS guarantee

    Publication Year: 2000, Page(s):41 - 48
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (572 KB)

    A novel parallel scheduling algorithm, namely a parallel solitary-request-first (PSRF) algorithm, is proposed to improve the performance of the multiple input-queued (MIQ) switch. The proposed algorithm is basically based on the three-phase scheme consisting of request, grant, and accept phases. The essential idea of PSRF is to select the solitary requests with preference. By doing so, PSRF enhanc... View full abstract»

    A new IP over WDM protocol with routing and transport capabilities is proposed. This protocol utilizes the concept of label switching and wavelength information of wavelength division multiplexing (WDM). This protocol uses labels and length information as the physical transport framing and data link delineation at the same time and can handle routing processes in the core network. Thus, it can spe...

    We propose a charging method for real-time variable bit rate (rt-VBR) traffic in ATM networks. Especially, we explore the effect of burstiness in the rt-VBR traffic to the charging in ATM networks based on the concept of statistical volume such as the effective bandwidth (EB). First, we describe the principles for charging in rt-VBR traffic. Next, we describe the effect of the burstiness to the re... View full abstract»

    Advances in high speed routing and switching devices in have made it possible to facilitate both new network services such as group communication, and to increase the level of router programmability. Programmability is considered as a feature not only allowing to better meet applications requirements (user viewpoint) but also to optimise network resources (provider viewpoint). We show how multicas... View full abstract»

    This paper proposes a “photonic adaptation layer” (PAL) to efficiently transport IP packets, ATM cells, and voice over a high-speed WDM photonic network while supporting QoS requirements. In this scheme, the PAL path is introduced as a virtual path from the ingress to the egress port of the photonic network. PAL frame encapsulates IP packets/ATM cells/STM data transparently. On PAL pat... View full abstract»

    The capability to optimally allocate network resources such as bandwidth is a key to the economical viability of modern telecommunication networks. Requirements such as, adaptive updating of bandwidth allocations to track dynamical load variations, and preferential treatment for some services at the expense of others, based on economic considerations, however, add to the complexity of the task.

    Next-generation optical network configurations are a mix of SONET/SDH and direct data over fiber networks with SONET/SDH networks carrying a larger number of data packets along with traditional T1/T3 channels. Current SONET/SDH architecture, however, is not efficient for transport of different data types on a single fiber (or wavelength). A hybrid data transport (HDT) protocol is described here th...

    Heavy-tailed distributions have been widely found in traffic characteristics like connection volumes or connection durations in today's data networks. The purpose of this paper is to show that these heavy-tailed distributions, besides the well-known undesirable features like producing self-similar, long-range dependent traffic, also exhibit desirable features in some cases. Two such cases are pres... View full abstract»

    The guaranteed frame rate service (GFR) is viewed as the most promising ATM service for carrying TCP/IP traffic over large distances. We study the behavior of differential fair buffer allocation (DFBA) in the context of an ATM WAN carrying TCP Reno traffic, with a special focus on fairness issues. The factors investigated are the buffer size, the MCR allocation and other DFBA parameters, the prese... View full abstract»

    Routers forward a packet based on the packet destination address. To do this, they must find the longest matching prefix with the packet destination address in the IP lookup tables. Expanding the size of the global network increases the size of the lookup tables. Increasing the communication line speed reduces the processing and search time since the packets must be switched at wire speed. This im... View full abstract»

    One of the most challenging issues in the deployment of multimedia services with real-time requirements over IP-based networks is the possibility to guarantee a given quality of service to the constituent flows involved in the calls.

    The overlaying of IP-based networks onto ATM subnetworks is a network configuration pattern found increasingly often. While IP networks traditionally only offer plain “best-effort” service they are now evolving to offer more sophisticated services. Nevertheless, the exact mechanisms for providing QoS in IP networks are not yet settled and essentially non-existing in today's production-... View full abstract»

    Providing quality of service (QoS) is one big goal of ATM networks. Looking at ATM networks, it becomes obvious that QoS-support requires many components on different layers working together. QoS has to be provided bottom-up from the network interface card up to the higher protocol layers and the applications. A basic building block for providing QoS on the higher layers is traffic shaping. This w... View full abstract»

    We investigate how alternate routing and trunk reservation can be used in the private network-network interface (PNNI) framework to enhance the routing performance of ATM networks. After determining the optimal trunk reservation parameters we show, that alternate routing with trunk reservation is superior to both direct routing and simple alternate routing under most traffic conditions.

    PNOs have observed that it has been very difficult to actually measure the performance of ATM networks. The problem they faced was that the materials contained in ITU-T recommendations were incomplete, contained inconsistencies and in some situations were too complex to be efficiently implemented in network equipment. This paper thus identifies the limitations in the standards related to ATM perfo... View full abstract»

    An important issue in the design of multi-service IP networks is to find appropriate mechanisms to provide different levels of quality of service (QoS) for different types of applications. In this paper, scheduling mechanisms for real-time traffic in a differentiated services IP network are studied.
