  • performance evaluation of Connectionless Service for atm networks
    Global Communications Conference, 1995
    Co-Authors: Duke P Hong, T Suda
    Abstract:

    This paper investigates the performance of the direct approach to Connectionless Service over ATM. The direct approach utilizes Connectionless servers, attached to or incorporated in a subset of the ATM switches, to provide a packet switching Service. The number of Connectionless servers and ATM connections utilized by the direct approach is found analytically and compared to alternative approaches. Furthermore, the effects of two architectural options that significantly impact the performance of Connectionless servers, the packet forwarding scheme (packet-based and cell-based) and the flow control scheme (static rate control and a dynamic proportional rate control) are also evaluated.

  • analysis of the server and connection based approaches to Connectionless Service for atm networks
    1995
    Co-Authors: Duke P Hong, T Suda
    Abstract:

    Author(s): Hong, Duke P.; Suda, Tatsuya | Abstract: Two major approaches for providing Connectionless Service for ATM networks are connection based and server based. In the connection based approach, the connection oriented Service of ATM is used to interconnected pairs of ATM end systems. The end systems are then responsible for providing a Connectionless Service to various other end systems via ATM connections. In the server based approach, Connectionless servers in the ATM networks directly provide a Connectionless Service. An end system may send all its packets to one Connectionless server where each packet is individually routed to other Connectionless servers en route to the destination. This paper examines analytically the resource requirements for these two approaches. Specifically, it finds the number of ATM connections, connection set-up rate and required number of Connectionless servers.

  • Connectionless Service for public atm networks
    IEEE Communications Magazine, 1994
    Co-Authors: B J Vickers, T Suda
    Abstract:

    The interconnection of Connectionless LANs and MANs over a connection-oriented B-ISDN presents a dilemma with regard to efficient interoperability. In order to provide solutions to this dilemma, there have been many techniques proposed. We describe and evaluate the architectural and conceptual alternatives available for the implementation of a Connectionless Service for public ATM networks. We also suggest a scheme through which best-effort Connectionless Service may be provided in public ATM networks using Connectionless servers and hop-by-hop flow control. There is as yet no consensus on issues such as bandwidth management, address resolution, Connectionless server forwarding modes, or Connectionless server topology, and therefore much of the area remains open for research. These research issues must be addressed, however, in order to realize the interoperability, and thereby the acceptance, of ATM. >

  • architecture and design of Connectionless data Service for a public atm network
    International Conference on Computer Communications, 1993
    Co-Authors: D F Box, D P Hong, T Suda
    Abstract:

    The backward compatibility dilemma introduced by the deployment of a high-speed, wide-area asynchronous transfer mode (ATM) network is examined. The problem is that emerging ATM network must be capable of transporting traffic sources such as digital voice and video, but many of the design choices that optimize ATM for these sources make the transport of traditional Connectionless data traffic difficult. The overlay of a virtual datagram network of Connectionless servers onto a public ATM network to provide Connectionless Service is proposed to solve the problem. This method provides low transfer delay and efficiently utilizes network resources. Architectural issues are described, and an implementation of a Connectionless server is presented. >

  • Design of Connectionless data Service for ATM networks
    1992
    Co-Authors: P. Hong, D F Box, T Suda
    Abstract:

    Author(s): Hong, Duke P.; Box, Donald F.; Suda, Tatsuya | Abstract: The advent of high speed, wide area ATM networks introducs a "backwards compatibility" dilemma. While emerging ATM networks must be capable of transporting future applications such as digital voice and video, many of the design choices made to optimize ATM for voice and video make the transport of traditional data traffic difficult. This paper will address some of these issues and propose possible solutions. This paper presents a promising method of providing Connectionless Service by buidling a virtual Connectionless network on top of a public ATM network with a subset of the switches acting as Connectionless servers. This method provides low transfer delay and low cost to the user.

  • local area network characteristics with implications for broadband network congestion management
    IEEE Journal on Selected Areas in Communications, 1991
    Co-Authors: H J Fowler, W E Leland
    Abstract:

    The authors examine the phenomenon of congestion to better understand the congestion management techniques that will be needed in high-speed, cell-based networks. The first step of this study is to use high time-resolution local area network (LAN) traffic data to explore the nature of LAN traffic variability. Then the data are used for a trace-driven simulation of a Connectionless Service that provides LAN interconnection. The simulation allows one to characterize what congestion might look like in a high-speed, cell-based network. When realistic data are applied to simple models of LAN interconnection, it is observed that during periods, congestion persists and losses can be significant; congestion losses cannot be avoided by modest increases in buffer capacity; consequences of misengineering can be serious; and, fortunately, most congested periods are preceded by signs of impending danger. >
