ABSTRACT:
The invention resides in a precise technique for determining the equivalent bit rate (EBR) of a variable bit rate (VBR) ATM connection. The technique extends a known single-source method developed by Gibbens and Hunt. The new technique applies to shared facilities and hence exploits the statistical-multiplexing gain. The calculation of the EBR is quite fast and is therefore suitable for real-time call-admission control in ATM switches. The admission criteria may be based on either the cell loss or cell delay.
