  • Characterizing bandwidth requirements of multiplexed connections with quality-of-service constraints

    Publication Year: 1995, Page(s):515 - 521

    Commonly proposed approaches for computing bandwidth requirements of multiplexed connections with quality-of-service (QOS) guarantees rely on “effective bandwidth”. Since the performance criterion used in these approaches characterizes only QOS requirements at a single multiplexing point, they cannot capture the impact of interactions in the network on bandwidth requirements for end-to...

    In this paper, we study the throughput characteristics of carrier sense multiple access with collision detection (CSMA/CD) local area networks (LANs) interconnecting with switching hubs. The interconnection schemes considered here not only increase the performance of CSMA/CD LANs to meet the evolving bandwidth requirements of today's applications, but also reduce the overhead costs when updating e...

  • A method for logic design of ATM adaptation layer protocol

    Publication Year: 1995, Page(s):536 - 542
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (552 KB)

    In an asynchronous transfer mode (ATM)-based broadband integrated services digital network (BISDN), an ATM adaptation layer (AAL) is needed to adapt each non-ATM application to the ATM layer. This paper proposes an abstract AAL logic design methodology which combines the concept of `quotient problem' defined by Calvert and Lam, 1987, with the concept of supervisory control in the context of discre...

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (592 KB)

    The interconnection of LAN/MANs to ATM networks is important for supporting connectionless (CL) applications geographically. Given that conventional flow control mechanisms have been eliminated to improve switching speeds, admission control will be crucial for an ATM network to protect itself from congestion. Since ATM networks are connection-oriented (CO) by nature, current admission control sche... View full abstract»

    A key B-ISDN functional principle is the support of a wide range of data, video and audio applications in the same network. Moreover, the network must be flexible and adaptable to meet the demands of current and future services. A set of emerging multimedia services is presented in context of the requirements they impose on B-ISDN signaling protocols. With these multimedia services in mind, we ext... View full abstract»

    Today the Asynchronous Transfer Mode (ATM) is extensively used on the level of public pilot networks. In the first stages of introduction these networks do not yet support signalling. However, the standardisation bodies ITU-TS (former CCITT) and ATM Forum have already produced first specifications for signalling in ATM networks. These specifications define the basic procedures for point-to-point s... View full abstract»

    We show that the modified hyperbolic congruential frequency hop codes have almost ideal properties for code division multiple access (CDMA) communications, that is, for any pair of the codewords they have at most two hits for any frequency shift under a synchronous environment and at most four hits for any time and frequency shift under an asynchronous environment. Efficient algorithms for decodin... View full abstract»

    Regular Cayley graphs like hypercubes and recently introduced star graphs play an important role in designing interconnection networks for multiprocessing systems; these graphs are regular and the degree of the nodes increases with the size of the graph (the number of nodes) either logarithmically or sub logarithmically. But, from a VLSI design point of view, constant degree networks are more suit... View full abstract»

    During the early days of commercial software development, cost and performance were the factors that received the most attention as an area for improvement. In the 1980's quality and productivity have received a great deal of attention. It appears that, in the 1990's reducing software development time will be one of the primary goals of large and small software companies alike. To this end it is a... View full abstract»
