Generic Cell Rate Algorithm - Description of The GCRA

Description of The GCRA

The GCRA is described by the ATM Forum in its User-Network Interface (UNI) and by the ITU-T in recommendation I.371 Traffic control and congestion control in B-ISDN . Both sources describe the GCRA in two equivalent ways: as a virtual scheduling algorithm and as a continuous state leaky bucket algorithm (figure 1).

    “Do not require a description of the countries towards which you sail. The description does not describe them to you, and to- morrow you arrive there, and know them by inhabiting them.”
    —Ralph Waldo Emerson (1803–1882)

    “Why does philosophy use concepts and why does faith use symbols if both try to express the same ultimate? The answer, of course, is that the relation to the ultimate is not the same in each case. The philosophical relation is in principle a detached description of the basic structure in which the ultimate manifests itself. The relation of faith is in principle an involved expression of concern about the meaning of the ultimate for the faithful.”
    —Paul Tillich (1886–1965)
