Traffic Management
Two traffic management standards are available from ITU-T and from The ATM Forum:
8. ITU-T Recommendation I.371, “Traffic Control and Congestion Control in B-ISDN”,
2nd Release, Geneva, Switzerland, March 1996
9. Traffic Management Specification Version 4.0, April 1996, The ATM Forum
As traffic management has many undefined aspects in research and under investigation,
numerous articles about it are published each year. The articles listed below provide the
basics for the principles used in the ABM device.
The cell level congestion occurring when several independent sources send random cell
traffic into one queue can be solved analytically. This scenario applies to the real-time
queue of a Scheduler. The required queue size for a given cell loss probability is calcu-
lated in this paper:

future Broadband ISDN”, International Journal of Digital and Analog Cabled Systems,
Vol. 2, 1989
In the case of bursty real-time traffic (VBR-rt), statistical multiplexing gain can be
achieved by the fact that it is very unlikely that many uncorrelated sources send bursts
simultaneously. The total bit rate to be reserved for an ensemble of such connections
can be lower than the sum of the individual peak bit rates. The following articles propose
algorithms to calculate the sum rate:
