    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (293 KB)

    The fiber distributed data interface (FDDI) is a 100-Mb/s local area network (LAN) that uses optical fiber as the medium. The FDDI protocol is based on a token ring access method. FDDI is being developed as an American National Standard (ANS) in Accredited Standards Committee (ASC) X3T9. FDDI is also being developed as an International Standard (IS) in ISO/IEC JTC1/SC 25. This paper is intended to... View full abstract»

    An examination is made of the future of LCN (local computing networks) standards from a technology, standards process, and user environment point of view. All three of these aspects of standardization must be considered if the future viability of LCN standards is to be ensured. While no answers are offered, a series of questions is posed that must be at least considered before the next generation ... View full abstract»

    Ring management is a recent addition to the ANSI FDDI (fiber distributed data interface) standard that provides a mechanism for solving two of the more difficult problems: discontinuities in the token path due to stuck faults, and ring initialization failures due to duplicate addresses. These problems are described, and the use of distributed management, as set out in the standard, to solve them i... View full abstract»

    FDDI (fiber distributed data interface) provides both the high bandwidth and low latency needed to match the increased capacity of future personal computers, at least for traditional LAN applications. The improved latency, however, is not low enough for a true multimedia LAN. What is needed is an access method that simplifies the interface to video and sound networks as well. FDDI-II is an extensi... View full abstract»

  • Using multicast communication for dynamic load balancing in local area networks

    Publication Year: 1989, Page(s):77 - 84
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (592 KB)

    A multicast-based algorithm is proposed for load balancing in a local computer network. The ability of a host to make its membership known to a multicast group based on its workload makes it possible to send a transfer request only to those hosts which have lower workload than the host that wants to transfer a task. This reduces the overhead of load balancing because a host does not waste computat... View full abstract»

    The author designs and analyzes the performance of a remote terminal protocol (RTP), called TAP, for use as a terminal access protocol in a 4BSD UNIX environment. He characterizes the workload by tracing user terminal activity on a multiuser timeshare machine. The trace analysis shows that user terminal traffic is bursty, with 99% of the traffic from the terminal being one byte long. The trace res... View full abstract»

    A serious problem in network management is the manner in which data is presented, as it is difficult to visualize a network by examining tabular data output. It is shown by examples that by presenting computer network data in graphical form instead of numerical, the network manager will be able to discover problems in the network much faster and more easily than with traditional methods.<<ET...

    The simple network management protocol (SNMP) is an application protocol that allows logically remote users to inspect or alter management variables. The SNMP is typically used for the management network of networks, or internets, which utilize the TCP/IP protocol suite. A brief introduction to the SNMP is presented, and its architectural principles are described. The transport paradigm and SNMP a... View full abstract»

    Even though IEEE 802.6 can cover longer distances than those of local area networks (LANs), it is limited by unfairness in terms of average access delay. The effect of distance on average access delay is analyzed based on homogeneous assumptions, and a technique to extend 802.6 over a wider area is proposed. The technique makes possible simplification of topology for wide area networks (WANs), whi... View full abstract»
