    After a brief introduction to the theory of Petri nets, the MTP (multicast transport protocols) for the distributed network management system is presented. The authors designed the group communication protocol which has low protocol-message overhead and efficiency. The atomic and reliable group communication protocol designed in the paper guarantees that each message sent to a group is delivered t... View full abstract»

    Since functional reduction is based on relation instance maps from a set of output places of transition to the corresponding set of input places in an adjacent transition, the concept of composition is formalized as a new transition, and is compounded from two joinable transitions with the merging of the places of two transitions after eliminating common places. This method has one handicap as a s... View full abstract»

  • A multicast protocol for network management system

    Publication Year: 1995, Page(s):364 - 368
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (535 KB)

    A new group communication protocol has been proposed and implemented for a distributed network management system. To reduce the protocol overhead, distributed and hierarchical approaches have been introduced: the group management function has been split into three functional entities. The first one is the local group manager (LGM) which manages one or more member(s) in one host. The second one is ... View full abstract»

  • Binary-routing: a routing scheme for high traffic networks

    Publication Year: 1995, Page(s):442 - 446
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (280 KB)

    Routing is the process of directing the track a message takes in order to get from the source node to the destination node. As the number of nodes in the network increases, and more network intensive activities occur, routing difficulties increases. The primary problem is the processing that each router has to perform to pass on each single packet. This paper proposes a system, called binary-routi... View full abstract»

  • A maximum entropy approach to the analysis of loss systems

    The maximum entropy principle allows us to obtain an estimate of the state probability distribution when our knowledge about the system is only the expected value of some functions of the system state. In this paper we explore the maximum entropy approach to evaluate the state probability distribution of loss systems where the call arrival processes are unknown or not specified. We present some nu... View full abstract»

  • Verifiable secret sharing and multiparty protocols in distributed systems

    In this paper, we propose verifiable secret sharing and multiparty protocols in a distributed system under the assumption that each participant can broadcast a message to all other participants and that each pair of participants can communicate secretly. The secrecy achieved is unconditional and does not rely on any assumption about computational intractability. Applications of these results to th... View full abstract»

    Recent measurement analysis obtained over real testbeds show that multimedia applications produce aggregated traffic well-described by bursty stochastic processes which exhibit long-range dependence. The paper presents a simulation comparison between the behaviour of a DQDB MAN driven by different sources: real multimedia traffic (collected by experimental measurement) and stochastic models used t...

    Publication Year: 1995, Page(s):493 - 497
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (432 KB)

    This paper focuses on the performance evaluation on two methods namely the leaky bucket and fast buffer reservation at the burst level for variable bit rate video signals. There has been a considerable amount of work on traffic shaping methods such as the leaky bucket. Much of this work has concentrated on the cell level instead of the burst level to generate randomly tokens at the cell level. Mos... View full abstract»

    Representing the dynamics of dialogue behavior is one of the most critical capabilities of an intelligent interface. When an intelligent interface monitors a user's strategies for solving a complex problem or accomplishing a goal, a discernible pattern of user interaction behavior emerges. This paper introduces and discusses a methodology to identify a user's task-specific expertise dynamically fo... View full abstract»

  • Options of ATM adaptation layer for MPEG video

    The design and performance analysis of a forward error protection scheme which uses the two dimensional error coding technique for the ATM adapttion layer (AAL) to support MPEG video services in ATM networks, are carried out. Our study has shown that the design of the forward error correction (FEC) code for the convergence sublayer (CS) in the AAL must be carefully considered because of the possib... View full abstract»

  • Evaluating performance of the MPQ policy for input and output queueing ATM switch supporting multiple traffic classes

    Publication Year: 1995, Page(s):352 - 356
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (372 KB)

    We propose a mixed priority queueing (MPQ) model to improve the quality of service (QOS) for 3 different classes of traffic in an ATM switch. A single stage input and output buffered nonblocking ATM switch is considered. In order to resolve a certain degree of external conflicts at the output ports, the switching fabric allows limited queueing at the output ports incorporating output buffers of a ...

    This paper focuses on definitions and models of multimedia distortion and fidelity, and their relations with multimedia synchronizations. The basic idea is that information of a multimedia object can be decomposed into content information (or non-time information) and time information. Time information can be either classified into centralized and decentralized time information, or classified into... View full abstract»

    The concept of multimedia capacity region (MCR) is used to characterize a workstation's capability in supporting multimedia processing with quality of service guarantees. Typically, the MCR depends on the process behavior, processing scheduling policy and the quality of service constraints. In most cases, an analytical method is not available to compute the MCR.

    Wavelength division multiplex (WDM) networks divide the bandwidth of a single optical channel into a number of non-overlapping wavelength channels and are regarded as future high-speed networks with a potential throughput in the order of Terabits. Inherent in this mechanism is the facility to utilise the capacity of the optical fibre more efficiently than existing single-channel high-speed network... View full abstract»

  • Congestion control for LAN/MAN interconnection

    Publication Year: 1995, Page(s):421 - 425

    We propose a congestion control scheme for interconnected networks where several local area networks (LANs) are connected to a high speed backbone network via gateways. In such a network, traffic congestion may occur due to the difference of transmission speed and/or workload between the high speed backbone and the lower speed LANs. For example, when several source gateways transmit packets destin... View full abstract»

    An integral equation approximation that combines the scattering-radiation conversion, the small perturbation technique and the spherical vector eigenfunction expansion method is employed in this paper to investigate the radio wave attenuation by a realistically distorted scatterer, i.e. the Pruppacher-and-Pitter (P-P) model raindrop. A simple and modified non-symmetric model that fits the Pruppach... View full abstract»

    Messengers constitute a new methodology for network-based operations. This paper investigates the use of messengers as a platform for hypertext generation over the World Wide Web (WWW). A messenger is a program that is executable on any computer on a network that provides the executing environment. There are two main WWW protocols, the hypertext transfer protocol (HTTP) and the hypertext markup la... View full abstract»

    In this paper, the impact of cell loss on the quality of service for MPEG video in ATM environment is investigated. It has been found that the consequence of the loss of video sequence header on picture quality can be tolerated even at a high cell loss ratio of 10-3 . The loss of GOP and picture headers results in a picture loss ratio which is only slightly higher than the cell loss rat... View full abstract»
