Bandwidth and capacity planning Definitions

  • B

    bandwidth

    Definition: Learn what bandwidth is and how the term is used as a synonym for signal frequency range, data transfer rate and capacity.

  • C

    capacity planning

    In information technology, capacity planning is the science and art of estimating the space, computer hardware, software and connection infrastructure resources that will be needed over some future period of time.

  • chatty protocol

    A chatty protocol is an application or routing protocol that requires a client or server to wait for an acknowledgement before it can transmit again.

  • E

    enterprise WAN

    An enterprise WAN is a corporate network that connects geographically dispersed users areas that could be anywhere in the world.

  • F

    frame relay

    Frame relay is an affordable way to transmit switched-packet data within LANs and WANs.

  • P

    Packet Order Correction (POC)

    Packet Order Correction (POC) is a technique for dealing with out-of-order packet delivery.

  • T

    T1 (T-1)

    Also see the T-carrier system, of which the T1 is a part.

  • W

    WAN clustering (geoclustering, high-availability clustering or remote clustering)

    WAN clustering, also called geoclustering, high-availability clustering or remote clustering, is the use of multiple redundant computing resources located in different geographical locations to form what appears to be a single highly-available system.

  • WAN optimization (WAN acceleration)

    WAN optimization, also known as WAN acceleration, is the category of technologies and techniques used to maximize the efficiency of data flow across a wide area network (WAN).

  • Wide Area Ethernet (WAE)

    Wide Area Ethernet (WAE) or Ethernet WAN (also sometimes referred to as fiber or LAN extension service ) is a network carrier service that delivers high-speed wide area network (WAN) connectivity, utilizing Ethernet as the connection method. Positioned as an alternative to traditional wide area connections such as leased line, frame relay or T1 services, Wide Area Ethernet simplifies linking remote sites and enables bandwidth-heavy applications such as multicast video streaming.

  • wireless WAN (Wireless Wide Area Network)

    A wireless WAN is a wide area network in which separate areas of coverage or cells are connected wirelessly to provide service to a large geographic area.
