Network Design Definitions

  • A

    adaptive routing (dynamic routing)

    Adaptive routing, also called dynamic routing, is a process for determining the optimal path a data packet should follow through a network to arrive at a specific destination. Adaptive routing can be compared to a commuter taking a different route to work after learning that traffic on his usual route is backed up.

  • ADSL (Asymmetric Digital Subscriber Line)

    Also see Fast Guide to DSL. ADSL (Asymmetric Digital Subscriber Line) is a technology for transmitting digital information at a high bandwidth on existing phone lines to homes and businesses.

  • asymmetric communications

    In telecommunications, the term asymmetric (also asymmetrical or non-symmetrical) refers to any system in which the data speed or quantity differs in one direction as compared with the other direction, averaged over time.

  • ATU-R (ADSL Terminal Unit - Remote)

    An ATU-R (ADSL Terminal Unit - Remote), sometimes called an "ADSL modem," is a hardware unit that is installed in any computer that uses a telephone company connection with Asymmetric Digital Subscriber Line (ADSL) service.

  • B

    B-channel (bearer channel)

    In the Integrated Services Digital Network (ISDN), the B-channel is the channel that carries the main data.

  • Broadband Integrated Services Digital Network (BISDN)

    BISDN is both a concept and a set of services and developing standards for integrating digital transmission services in a broadband network of fiber optic and radio media.

  • Broadband over Power Line (BPL)

    Broadband over Power Line (BPL) is a technology that allows Internet data to be transmitted over utility power lines.

  • bus network

    A bus network is an arrangement in a local area network (LAN) in which each node (workstation or other device) is connected to a main cable or link called the bus.

  • C

    channel-associated signaling (CAS)

    Channel-associated signaling (CAS) is signaling (for example, in a T-carrier system line) in which control signals, such as those for synchronizing and bounding frames, are carried in the same channels as voice and data signals... (Continued)

  • chiral fiber

    Chiral fiber is a specialized optical fiber medium with its core twisted into a helical shape.

  • circular mil

    The circular mil is a unit of area used especially when denoting the cross-sectional size of a wire or cable.

  • Cisco LISP (Location Identifier Separation Protocol)

    LISP (Location Identifier Separation Protocol) is a routing and addressing architecture developed by Cisco Systems. LISP creates two addresses for each network node: one for its identity and another for its location in the network.

  • client/server (client/server model, client/server architecture)

    Definition: Learn what the client/server model is, how it works and why you are using it right now to view this Web page.

  • Clos network

    A Clos network is a type of non-blocking, multistage switching architecture that reduces the number of ports required in an interconnected fabric.

  • cloud

    In telecommunications, a cloud is the unpredictable part of any network through which data passes between two end points.
