Research on the Congestion Control of Broadband Integrated Service Digital Network Based on ATM

Congestion control technique is important for B-ISDN. In terms of the latest recommendation of ITU-T, the basic ideas, operational mechanism and functions are analyzed. Flow control and congestion control are the two levels included in the congestion control mechanism of B-ISDN. Congestion control of B-ISDN is completed by cooperating flow control with congestion control. Congestion control mainly includes selective loss of cell and congestion indication, which is an important and complex problem to be solved
