Data Center Infrastructure Definitions

  • A

    application delivery controller

    An application delivery controller (ADC) is a network component that manages and optimizes how client machines connect to web and enterprise application servers.

  • F

    fast retransmit and recovery (FRR)

    In TCP/IP, fast retransmit and recovery (FRR) is a congestion control algorithm that makes it possible to quickly recover lost data packets.

  • M

    MOSPF (Multicast Open Shortest Path First)

    MOSPF (Multicast Open Shortest Path First) is an extension to the OSPF (Open Shortest Path First) protocol that facilitates interoperation between unicast and multicast routers... (Continued)

  • N

    NBAR (Network Based Application Recognition)

    Network Based Application Recognition (NBAR) is a mechanism that classifies and regulates bandwidth for network applications to ensure that available resources are utilized as efficiently as possible. Cisco Systems developed NBAR as part of its Content Networking platform for implementing intelligent network services... (Continued)

  • S

    shortest path bridging

    Shortest path bridging, or 802.1aq, is the IEEE’s specification for enabling multi-pathing in the data center. Shortest path bridging is similar conceptually to its IETF counterpart, Transparent Interconnection of Lots of Links (TRILL).

  • SMDS (Switched Multimegabit Data Service)

    SMDS (Switched Multimegabit Data Service) is a public, packet-switched service aimed at enterprises that need to exchange large amounts of data with other enterprises over the wide-area network on a nonconstant or "bursty" basis.

  • spanning tree protocol (STP)

    Where two bridges are used to interconnect the same two computer network segments, spanning tree is a protocol that allows the bridges to exchange information so that only one of them will handle a given message that is being sent between two computers within the network. (Continued)

  • T

    top-of-rack switching

    Top-of-rack switching refers to a distributed data center architecture where one or more Ethernet switches is installed in a rack, then uplinked using high-bandwidth fiber optic connections to a central, high-density distribution point.

  • Transparent Interconnection of Lots of Links (TRILL)

    Transparent Interconnection of Lots of Links (TRILL) is the Internet Engineering Task Force’s specification for enabling multi-pathing in the data center. The protocol is intended to replace the spanning tree protocol.
