Method and device for detecting the congestion of a transmission link

摘要

Detection of the congestion of a link based on an exchange of messages between a sender and a receiver, a sender and several receivers or several senders and a receiver. These items of equipment are connected to the ends of a transmission channel. One of the items of equipment is designated master and the other slaves. These exchanges are aimed at allowing the master to calculate and to compare the bit rate of the data sent and the bit rate of the data received. A divergence in the bit rates calculated is evidence of a congestion of the link. All the exchanges are made within the application layer and therefore do not involve the underlying layers.
