  • dynamic bandwidth control of the virtual path in an Asynchronous Transfer Mode network
    IEEE Transactions on Communications, 1992
    Co-Authors: S Ohta, Kenichi Sato
    Abstract:

    The virtual path concept has several valuable features to construct an economical and efficient Asynchronous Transfer Mode (ATM) network. One of them is bandwidth control which affords transmission efficiency improvement through statistical sharing of capacity. An effective bandwidth control algorithm and its calculated performance are described. Network performance with the algorithm is evaluated, and the bandwidth control is shown to successfully improve network transmission efficiency with only a slight increase in processing load compared to the fixed bandwidth scheme. A method is also proposed to equalize call loss probability for each virtual path. The effectiveness of the method is demonstrated by analysis. >

  • VBR video transmission with isochronous and Asynchronous Transfer Mode over wireless 1394
    Electronics and Communications in Japan (Part I: Communications), 2004
    Co-Authors: T. Takazawa, Yasuhito Utsunomiya, Y. Komoriya, Masaki Bandai, Iwao Sasase
    Abstract:

    We propose a VBR video transmission scheme with isochronous and Asynchronous Transfer Mode over Wireless 1394. In the proposed scheme, to decrease the idle bandwidth in the isochronous area, a video station which uses the isochronous Transfer Mode is assigned bandwidth equivalent to the average rate of the video stream. Video data over the average rate are transmitted in Asynchronous Transfer Mode, and video stations have higher transmission priority than data stations in Asynchronous Transfer Mode. By computer simulations, we show that the proposed scheme can improve the channel utilization performance and the waiting time performance, and that it is effective for VBR video transmission. © 2004 Wiley Periodicals, Inc.

  • Asynchronous Transfer Mode (ATM) Technology and Applications
    Social Science Research Network, 2015
    Co-Authors: Jeffrey Ray
    Abstract:

    The purpose of this paper is to summarize the Asynchronous Transfer Mode (ATM) technology and determine where it is in its evolutionary development. Technologies that fragment data into small pieces typically have very poor performance because there is no mechanism to detect and retransmit lost cells when a piece of the data is lost in transit. The only way to recover the damaged cell is to retransmit the entire large packet again. An alternative to inefficiently retransmitting the entire packet is to only retransmit the individual cells that are lost or damaged. The ATM technology incorporates the ability to retransmit only the cells in each packet that were not received properly. It also enhances transmission performance by reducing flow control activity required at each network link. Surveying recent products serves as an effective barometer for determining how the ATM technology is evolving. State-of-the-market ATM products indicate that an ATM design solution provides unmatched speed, fault-tolerance, and scalability through multiple, meshed inter-switch connections that support load-sharing across networks. At its current point in evolutionary technological development, ATM is a key enabling communications technology that will introduce new applications to users and network providers, as well as provide higher bandwidth capacity to networks. Because of its high-bandwidth capacity and cell-oriented architecture, ATM is the dominant infrastructure for delivering virtually all types of communications, including data, voice, image, and multimedia, into the buildings and desktops of users around the world. By carefully considering critical performance issues, and accommodating existing legacy systems during ATM implementations, the telecommunications industry has insured that ATM will not only be the design solution of the future, but that it can provide cost effective applications today as well.
