, the emphasis on providing low latency and high link speeds at a low cost precludes the use of intelligent switches with large buffers. In this paper, we present a simple scheme that provides "best effort" bandwidth reservation to delay sensitive traffic in a wormhole routing LAN. The idea behind

We demonstrate that Ethernet LAN traffic is statistically self-similar, that none of the commonly used traffic models is able to capture this fractal-like behavior, that such behavior has serious implications for the design, control, and analysis of high-speed, cell-based networks

Wormhole routing is a simple, low-cost switching scheme often used for supercomputer interconnections. Recently, at also has been applied to high-speed local area networks to support applications demanding high-datarate communications, such as cluster computing. The drawback to wormhole routing

Topology changes, such as switches being turned on/off, hot expansion, hot replacement or link re-mapping, are very likely to occur in NOWs and clusters. Moreover, topology changes are much more frequent than faults. However, their impact on real-time communications has not been considered a major problem up to now, mostly because they are not feasible in traditional environments, such as massive parallel processors (MPPs), which have fixed topologies. They are supported and handled by some current and future interconnects, such as Myrinet or Infiniband. Unfortunately, they do not include support for real-time communications in the presence of topology changes.

Abstract: This study is concerned with a practical application of distributed artificial intelligence for managing the high data rate bus structured local area computer network that uses deterministic multiple access protocol. In the selected network that is managed using distributed artificial intelligence, the dynamic sharing of the available bandwidth among stations is achieved by forming “train to which each station may append a packet after issuing a reservation. Reservation and packet transmissions are governed by the reception of control packets (token) issued by the network end stations. Managing approach that was suggested depends on using intelligent autonomous agents, which are responsible for various tasks among it: election of the end stations, the recovery from failures, and the insertion of new stations in the network. All these tasks are based on the use of special tokens.

Emerging high-speed networks will allow machines to access remote data nearly as quickly as they can access local data. This trend motivates the use of cooperative caching: coordinating the file caches of many machines distributed on a LAN to form a more effective overall file cache. In this paper

Introduction ATM (Asynchronous Transfer Mode) is a set of international standards for sending large amounts of voice, data and video information simultaneously over a single network at speeds up to a thousand times faster than is commonplace today. It is aimed to transport virtually every

Abstract—Link adaptation to dynamically select the data transmission rate at a given time has been recognized as an effective way to improve the goodput performance of the IEEE 802.11 wireless local-area networks (WLANs). Recently, with the introduction of the new high-speed 802.11a physical layer

This thesis focuses on the design of power- and area-efficient parallel integrated re-ceivers for multiple antenna wireless LAN systems. These receivers are part of an indoor parallel radio system that achieves 1 gigabit per second data rates and enables high bandwidth wireless communication
