Abstract:
Detection of the congestion on a link based on an exchange of messages between a sender and a receiver, one sender and several receivers or several senders and one receiver. This equipment is connected to the ends of a transmission channel. One of the items of equipment is designated as the master and the others slaves. These exchanges are aimed at enabling the master to calculate and compare the rate of the data send and the rate of the data received. A divergence in the rates calculated reveals a congestion on the link. All these exchanges are made in the application layer and therefore do not involve the underlying layers.

Claim (Index 7):
A method for detecting congestion on a transmission link, the transmission link having two ends, one or more items of equipment being connected to each end of said transmission link so that at least one of said ends has only one item of equipment connected thereto, the method comprising:\n determining a master and one or more slaves among the items of equipment connected to the ends of the transmission link, the master always being the item of equipment that is solely connected at one of the ends of the transmission link; exchanging data via said transmission link during a predetermined period; calculating, by each item of equipment, in application layer of said item of equipment, a data rate of data sent or received during the predetermined period via said transmission link; exchanging, at initiative of the master and at the end of the predetermined period, messages between the master to the at least one slave, so that at least one of the items of equipment gathers the data rates calculated by the master and by the at least one slave for the predetermined period, and wherein the exchanged messages are messages in application layer; determining, in application layer, that a congestion occurs, when the data rate of data received at one of the ends of the transmission link is less than the data rate of data sent at the other end of the transmission link; and informing a quality of service management system, when a congestion occurrence via the transmission link has been determined, that said congestion has occurred, so that service admission at boundaries of a quality of service domain be adapted to the congestion occurrence. wherein the messages exchanged are as follows: sending, by the master, a request to the at least one slave; sending, by each slave, when the request is received from the master, a response to said request, wherein the request and each response are messages in application layer and wherein the master determines whether congestion occurs from the data rate calculated by the master and further from the data rate calculated by the at least one slave, wherein said the data rate calculated by the at least one slave is contained in said response sent by said at least one slave. further comprising: calculating a round trip time, when successive responses are received by the master, and predicting that congestion occurs, when a gradual extension of the round trip appears between the successive responses, wherein the gradual extension appears when the calculated round trip time continuously increases along the successive responses.
