  • The future of substrate data private line networking

    Publication Year: 1992 , Page(s): 30 - 35
    Request Permissions | Click to expandAbstract | PDF file iconPDF (1158 KB)  

    Private line networking for data applications using data rates equal to or less than 64 kb/s, referred to as substrate, is reviewed. Examples of substrate data applications include: automatic teller machine networks, banking teller platforms, and airline flight reservation systems. The fundamental point-to-point and multipoint topologies used in substrate data private line networking are described... View full abstract»

    A private network supports the information interchange requirements of a community of interest. It is a system consisting of transmission, demultiplexing, and switching components providing an information movement and management (IMM) infrastructure. The networks provide a customized operations environment with predictable service objectives and cost. The market drivers, legislative events, and en... View full abstract»

    Frame relay is a standardized interface that provides multiplexed access to bandwidth-on-demand backbone networks and delivers LAN-like performance over a wide area. It is shown that use of frame relay can benefit private networks. The multiplexed physical interface reduces the number of ports required on expensive bridge, router, and controller equipment, as well as the number of expensive commun... View full abstract»

    The evolution of T1-based private networks is reviewed. It is shown that as a result of bursty data, voice/data segregation, and processor advances, data networks are becoming packet-based. The need for efficient transport of data, and possibly voice, point to a frame-based system with the possibility of eventually moving to a cell-based system. An architecture for supporting connectionless transp... View full abstract»

    Frame relay is a significant networking technology in the current data networking environment. Given its inherent advantages, it is particularly well-suited to LAN interconnection. In a public network, frame relay has key advantages for end users in terms of performance and cost efficiency. The effectiveness of frame relay in public networks, the management of public frame relay networks, the evol... View full abstract»

    Virtual networks (VNs) are logical subnetworks contained within larger long-distance networks. VNs make use of the long-distance network to offer voice and data transport and a set of customer-controllable call monitoring and management features. The historical development and motivation for VNs are examined, and the VN architectural components are described. Call flows for on-net and off-net voic... View full abstract»

    Corporate data constitutes one of the most important assets possessed by corporations today. It provides the building blocks to form the information that underlies the operation of an enterprise. Because corporate data is created, managed, and stored in many forms and places, its value is directly related to the capability of its users to assess, manipulate, move, and manage it. It is argued that ... View full abstract»
