    Past and current campus data networks generally utilize connectionless network layer protocols like IP. Future networks are expected to use ATM which provides a connection-oriented service. New ATM switches are coming to market with baseline parameters such as the number of concurrent SVCs supported and the number of call setups possible per second. These parameters will determine the usefulness o... View full abstract»

    In 1993, the authors described the design of the AN2 switch which supports high-performance distributed computing. The switch's operation is based on the parallel iterative matching algorithm to find a maximal matching between the inputs and the outputs of the switch. The number of iterations needed to find a maximal matching in their algorithm is N in the worst case, and of time complexity O(log ... View full abstract»

  • A fault-tolerant architecture for ATM networks

    Publication Year: 1995, Page(s):29 - 36

    The asynchronous transfer mode (ATM) is the transfer mode recommended for B-ISDN by CCITT. In this paper, we propose a self-routing fault-tolerant switching architecture for ATM networks. The proposed architecture uses subswitches and extra links to provide many alternative paths, and hence can tolerate multiple faults. Analytical results show that the number of redundant paths increases exponenti... View full abstract»

    The congestion control in ATM cell level is one of the important functions in ATM networks. This function has been mainly discussed by the ATM forum. The forum selects the congestion control based on transmission rate as a default control scheme. In particular, EPRCA (Enhanced proportional Rate Control Algorithm) is the most promising candidate for rate base control schemes. However, the control s... View full abstract»

    Introduces the software structure of the call control function for ATM (Asynchronous Transfer Mode) systems. There are many systems to be developed for ATM Networks which have the call control function. So it is valuable to design the software structure of the call control function to have reusability and portability.

  • An efficient terminal-pair reliability algorithm for network management

    Publication Year: 1995, Page(s):53 - 61
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (764 KB)

    Terminal-pair reliability in network management determines the probabilistic reliability between the two nodes of a network, given failure probabilities of all links. The problem has been successfully solved by the path-based partition method, network reduction technique, and the combination of the two. The path-based partition algorithm, however, requires the repeated execution of a path-search p... View full abstract»

    Traffic management in ATM networks aims for the controlled use of network resources to prevent the network from becoming a bottleneck. This is a very complex task due to the random nature of the traffic arrival pattern and contention for network resources. In this paper we deal with one of the most important aspects of traffic control: "the policing". It has the role of ensuring that each source c... View full abstract»

    WDM networks in general depend on transmitters and receivers that are precisely tuned to predetermined fixed wavelengths. Robust WDM is an approach aimed at relaxing manufacturing and operating wavelength tolerance requirements, which will lead to cost effective implementations. In this approach, connections are based on dynamically selected wavelengths as opposed to using fixed wavelength channel... View full abstract»

    This paper introduces the concept of time slot synchronization in time-wave division multiplexed (TWDM) multihop lightwave networks. It is shown that the time slot assignments of the intermediate nodes in a multihop path have significant effect on the end-to-end message delay. This is different from traditional notions in routing, where the hop count and congestion control are the primary concerns... View full abstract»

    In ATM networks the usage parameter control function must be defined very carefully to avoid network congestion due to users violating their negotiated traffic contract intentionally or unintentionally. This control function operates on the basis of connection traffic descriptors and is located at the network access. Connection traffic descriptors, which describe the characteristics of a source, a... View full abstract»
