    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»

    In this paper we introduce the code division methodology into switching applications. The proposed method is applied in both satellite and terrestrial networks which is called switched code division multiple access (SW/CDMA). The SW/CDMA networks include the following: the satellite switched code division multiple access (SS/CDMA), for on-board routing in multibeam satellites; the base station-swi... View full abstract»

    We examine the application of wireless ATM protocol in a mobile satellite communication network. We explain the concept of the wireless ATM networks and how we can utilise the advantageous characteristics of the ATM (such as QoS support) in the next generation broadband satellite networks. In particular, we consider the performance of handoff and routing algorithms in satellite systems. As the mob... View full abstract»

    The rerouting of connections for handover in a broadband mobile cellular network is investigated. We address networks with a connection-oriented backbone, which supports quality-of-service (QoS). Moreover it is assumed an IP-style multicast on top of the connection-oriented network. We advocate to utilize the IP-style multicast in order to reroute connections for handover. Three rerouting schemes ... View full abstract»

    Switches with input buffers can potentially provide high capacity, because they do not involve multiplexing at output ports, and inputs can operate at high bit-rates. We have previously proposed an algorithm for packet scheduling in high-capacity switches, termed round-robin greedy scheduling (RRGS). RRGS completely removes head-of-line (HOL) blocking at terabit capacity. However, RRGS cannot prov... View full abstract»

  • Charging the real-time VBR traffic in ATM networks

    Publication Year: 2000, Page(s):419 - 424
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (396 KB)

    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»

    We propose a new data link control protocol for wireless ATM networks. This new protocol can support both real time and non-real-time services by adopting different error control mechanisms. For real-time traffic, only forward error control (FEC) is used for error correction. For non-real-time traffic, a hybrid automatic repeat request (ARQ) scheme is adopted to reduce the cell loss ratio to a min... 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 present a procedure to evaluate the parameters of the LEAP (linear bounded arrival processes) traffic characterisation when a stochastic model of considered traffic flow is available. The procedure, based on an equivalent queuing system, has been applied to a VoIP (voice over IP) scenario in a DiffServ (differentiated services) network architecture. In particular, we consider the characterisati... View full abstract»

    Traffic control for point-to-multipoint ABR services in ATM networks has been studied extensively, but this is not the case for multipoint-to-point (mp-p) traffic control. No consensus has been reached concerning the issue of fairness of bandwidth allocation among multipoint connections, or between point-to-point and multipoint connections. Existing mp-p traffic control schemes for ABR services ei... View full abstract»

    A new packet discard scheme called the forgiveness mechanism that can be plugged into the existing buffer management schemes to remarkably enhance throughput and fairness of TCP running over ATM-UBR service is developed. Our scheme does not require per VC accounting but per VC-state where only one bit is needed. Our focus is on demonstrating and analyzing the effect of the forgiveness mechanism wh...

    In this paper, we present a new network design problem that is applicable for designing virtual paths (VPs) in an asynchronous transfer mode (ATM) network to efficiently support multicast applications. We first address several alternatives for the solution and compare their properties. Then we focus on a new solution which sets up a semi-permanent VP layout (VPL) and constructs VC trees for differ... 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.

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (392 KB)

    In order to be able to characterize a packet loss process accurately, short-term packet loss ratios need to be taken into account in addition to the long-term packet loss ratio. We propose to characterize a packet loss process by using a deterministic loss model which takes into account the maximum packet loss ratio, short-term packet loss ratios, and the long-term packet loss ratio. We also propo... View full abstract»

    We propose a new multiple access control (MAC) protocol for wireless ATM systems, in which user demands are highly heterogeneous and can be classified as CBR, VBR, and ABR. Our protocol is motivated by two of the most significant drawbacks of existing protocols: (1) the channel condition is ignored or not exploited, and (2) inflexible or biased time slots allocation algorithms are used. Indeed, ex... 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.

    Audio-visual and other multimedia services are seen as an important source of traffic for current telecommunications networks, including ATM networks. There has been an emerging interest in using ATM for wireless transmission. Because ATM is primarily designed for an essentially error-free environment, in the wireless context the sources of errors and their consequences must be thoroughly understo... View full abstract»

    The key issue at a branch-point switch for point-to-multipoint (multicast) available bit rate (ABR) flow control is how to consolidate backward resource management (BRM) cells returning from each branch to avoid feedback implosion. However, consolidating BRM cells at a branch point can cause undesirable effects such as consolidation noise, consolidation delay, and consolidation loss. This paper fi... View full abstract»

    A performance study of the explicit congestion notification (ECN) mechanism in the transmission control protocol (TCP) over ATM (asynchronous transfer mode) networks is presented. TCP's congestion control is enhanced so that congestion is indicated by not only packet losses as is currently the case but an agent implemented at the ATM network's edge as well. Our simulation experiments show that TCP... View full abstract»
