ABSTRACT:
As long as a queuing network node (Q) is not congested, it returns to the source terminals (S1, S2, S3, S4) transmitting data packets through this queuing network node (Q), upper packet rate values (ER) which are proportional to the actual packet rate values (CCR). The transmit rate of a source terminal (S1, S2, S3, S4) upon receipt of the upper packet rate value (ER), is controlled so that it stays below this upper packet rate value. In this way, the queuing network node (Q) allows its aggregate input rate to increase in a controlled, smooth way and does not rely on the sources (S1, S2, S3, S4) themselves. Once the queuing network node (Q) gets congested a fair share algorithm is used to determine which source terminals have to decrease their transmit rates and which source terminals are allowed to further increase their transmit rates.
