An atm transmission system with a variable transmission rate

Abstract

A cell including a time stamp, first cell sending rate, first requested cell sending rate is transmitted from a transmitting side to a receiving side. At the receiving side a second cell sending rate is determined based on the first requested cell sending rate, and a second requested sending rate is determined based on the first cell sending rate and the cell discard information. The second requested cell sending rate is transmitted from the receiving side to the transmitting side to determine the first cell sending rate based on the cell discard information detected at the receiving side. Therefore, the cell sending rate is determined in accordance with a frequency of the discard of the cells so that the cell sending rate is decreased when the cell discard occurs and the cell sending rate is increased when the cell discard does occur.
