Description

ABSTRACT:
In a method and circuit arrangement for forwarding message cells supplied by an ATM communication equipment unit, a peak bit rate as well as an upper limit for an average bit rate and a burst tolerance are determined as characteristic parameters for at least a part of the virtual connections proceeding via the ATM communication equipment. For forwarding the message cells belonging to these virtual connections, a minimum delay time by which the forwarding of a message cell is at least delayed is calculated according to the criterion of the plurality of message cells incoming and outgoing per time unit during the course of the respective virtual connection, taking the peak bit rate into consideration. On the other hand, a maximum delay time by which the forwarding of a message cell is to be at most delayed is calculated according to the criterion of the plurality of message cells incoming and outgoing per time unit during the course of the respective virtual connection taking the upper limit of the average bit rate into consideration. Taking the calculated minimum and maximum delay time into consideration, finally a delay time is determined for forwarding a message cell present at the moment.
