Frame Relay - Committed Information Rate (CIR)

Committed Information Rate (CIR)

Frame Relay connections are often given a committed information rate (CIR) and an allowance of burstable bandwidth known as the extended information rate (EIR). The provider guarantees that the connection will always support the CIR rate, and sometimes the EIR rate should there be adequate bandwidth. Frames that are sent in excess of the CIR are marked as discard eligible (DE) which means they can be dropped should congestion occur within the Frame Relay network. Frames sent in excess of the EIR are dropped immediately. All traffic exceeding the CIR is marked discard eligible.

Famous quotes containing the words committed, information and/or rate:

    To punish a man because he has committed a crime, or because he is believed, though unjustly, to have committed a crime, is not persecution. To punish a man, because we infer from the nature of some doctrine which he holds, or from the conduct of other persons who hold the same doctrines with him, that he will commit a crime, is persecution, and is, in every case, foolish and wicked.
    Thomas Babington Macaulay (1800–1859)

    Computers are good at swift, accurate computation and at storing great masses of information. The brain, on the other hand, is not as efficient a number cruncher and its memory is often highly fallible; a basic inexactness is built into its design. The brain’s strong point is its flexibility. It is unsurpassed at making shrewd guesses and at grasping the total meaning of information presented to it.
    Jeremy Campbell (b. 1931)

    “Terence, this is stupid stuff:
    You eat your victuals fast enough;
    There can’t be much amiss, ‘tis clear,
    To see the rate you drink your beer.
    —A.E. (Alfred Edward)
