A New Approach to Rate-Based Traffic Control Methods

: This paper studies the behaviour of rate-based traffic control mechanisms for ATM networks, and evolves algorithms useful for call admission control decisions. The analytical model demonstrates a new approach to adapt the cell transfer delay parameter positively with increases in the traffic utilisation factor. Further work with simulation models have demonstrated that, in cases of traffic control schemes employing leaky bucket and feedback-based rate control, increases in the average interarrival period, results in an unexpected increase of delay and delay variance. This is observed under conditions of a ratio of the token generation or multiplexer service rate to average cell arrival rate, that is kept constant. These results have been confirmed against the analytical model for simple multiplexer and leaky bucket controlled buffer schemes, fed with cells having geometrically distributed interarrival times. 1.
