Abstract： |
The invention is an ECN-based forecasting and verifying congestion control method, firstly using the difference between two adjacent packets to calculate forecast parameters of a current packet, by this recurring to the corresponding forecast queue length of, and able to refer to the congestion conditions of nodes to correct the forecast length as a common forecast threshold value for all the packets; taking 2 x the first packet delay as signal transmitting time and all the packets as forecast packets in order to find a forecast value of average queue length of all the packets, a receiving end compares the difference between the forecast value and the forecast threshold value with predicted floating value of the forecast value, so as to be able to send a confirm packet increasing, decreasing or keeping the length of congestion window to the source end, convenient for the source end to regulate the packet transmitting speed. This receiving end driving method has the advantage of reducing loss rate and average packet delay at the same time, has stale and higher network utilization ratio and can also forecast the network's congestion conditions. |
