    The use of distributed systems has been constantly evolving during the last decade, a fact due to their lower aggregate cost, greater availability and higher flexibility. Distributed algorithms can, in addition, exploit the possibility offered by these systems for parallel execution and more sufficient use of resources. The paper describes a friendly environment supporting the development and exec... View full abstract»

    The design and understanding of fault-tolerant open distributed systems is a very difficult task. We have to deal with not only all the complex problems of open distributed systems when all the components are well, but also the more complex problems when some of the components fail. This paper proposes a fault-tolerant computing model on open distributed systems. The performance of the model is si... 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»

    Finding an optimal topology for a wide area network is a complex task which involves solving some form of simultaneous constrained optimization problem. Heuristic approaches have been widely used for solving this class of problems. This paper discusses the formulation of this class of problems as optimizing the topology of an artificial neural network and the use of genetic algorithms as heuristic... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (312 KB)

    The current model of computer communication is based on Shannon's (1949) model consisting of a sender, a channel and a recipient, where the sender sends a packet of data, along a channel to the recipient. Usually there are two channels, one each direction, allowing data flow in both directions. A protocol can be understood as a procedure which enhances the quality of the message exchange. Messenge...

  • Pulse time modulation for subcarrier multiplex (SCM) systems

    Publication Year: 1995, Page(s):450 - 454
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (296 KB)

    Subcarrier multiplexing (SCM) is an attractive multiplexing technique to deliver broadband services over optical fibres. The majority of existing systems employ an analogue signal for optical transmission and therefore the performance of these systems are limited. This paper proposes to improve SCM system performance by converting the analogue SCM signal into a pulse time modulated signal for opti... View full abstract»

  • Temporal behavior between the packet loss bursts in ATM networks

    Publication Year: 1995, Page(s):337 - 341
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (488 KB)

    In future broadband networks based on asynchronous transfer mode (ATM) transmission and switching technology, the dominant kind of impairment is expected to be packet (ATM cell) losses. The use of forward error correction (FEC) codes has been proposed as a way to overcome these losses. However, the maximum length of a lost packet string that a packet loss recovery scheme can be designed to recover... View full abstract»

    This paper describes a service by which users will be able to select, configure and activate multimedia services in a multivendor broadband environment. The service interface hides the difficulties and details of handling these complex services from the application. An abstract model is defined that accommodates an extensive set of services involving communication and end-systems. The paper define... View full abstract»

  • Modelling of variable bit rate signals using burstiness in ATM networks

    Publication Year: 1995, Page(s):498 - 502
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (416 KB)

    This paper focuses on the use of the burstiness parameter to model video signals in ATM networks. There has been a considerable amount of work on traffic models using on-off processes with independent distributions which are deemed to be approximate to the traffic in ATM networks. Much of this work has concentrated on the cell level instead of the burst level to formulate the model. Asynchronous t... View full abstract»

    In this paper the capture probabilities, Cn, defined as the probability that any of n contending packets is correctly received, are found, with reference to a random access mobile radio communications system in the presence of fading, shadowing, and near/far effect. A Ricean model for fading, which is more general than the well-studied Rayleigh fading, is then considered. The capture pr... View full abstract»

    There are increasing demands for the expansion of high quality, intelligent communication networks. Therefore, we need to manage the various communication networks effectively. In other words, the demands for integrated network management (INM) are on the increase. However, each of these networks is managed by its own OMN (operation management system).

  • Virtual channel and path allocation in ATM networks

    Publication Year: 1995, Page(s):81 - 85
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (400 KB)

    An asynchronous transfer mode (ATM) network provides a connection-oriented service by establishing a virtual channel (VC) between a source and destination node. Virtual paths (VPs) facilitate virtual channel allocation by partitioning network resources along pre-calculated routes. This paper proposes a framework for the allocation of VCs and VPs in an ATM network. Our approach is based on approxim... View full abstract»

    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (372 KB)

    Cell delay variation (CDV) has to be minimized in the access network for the ATM traffic, specially, if it is isochronous traffic, and if it is traversing over a wide area network. This paper considers the interworking of cyclic reservation multiple access (CRMA) LAN/MAN with a wide area ATM network and proposes a simple modification in the CRMA protocol which minimizes the access delay for the AT...

    The OSI (open systems interconnection) has been increasingly recognized and used for interconnection among different communications systems. Usually, conformance testing or interoperability testing is done to confirm the interconnectability of those different systems. But it is usually recognized that only these types of testing are inadequate for interconnectability confirmation. We have develope... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (576 KB)

    This paper presents a data compression scheme for Chinese text files. Due to the skewness of the distribution of Chinese ideograms, the Huffman coding method is adopted. By storing the Huffman tree in the coding table and representing the Huffman tree using the Zaks sequence, the algorithm produces significant improvement on the compression results. The proposed method is evaluated by comparing it... View full abstract»
