A method for signaling a piece of congestion information regarding a first data stream routed by a first node in a network. The method includes the following acts implemented by a second node via which the first data stream and at least a second data stream are routed: obtaining a piece of congestion information regarding the second data stream, the congestion information indicating that a third node, via which the first data stream is routed, has detected a congestion situation for a routing of the second stream in a data transfer plane; checking that the first data stream has a priority level lower than that of the second data stream; and sending, to the first node, a control message in a control plane, the control message carrying the congestion information.

Technique for signalling congestion in a packet communication network

A method of transmitting a data stream previously coded according to an adaptable coding between a first terminal and a second terminal through the intermediary of a session established according to an HTTP-based transport protocol is disclosed. In one aspect, collection is by the first terminal of a set of context information relating to the session, to the first terminal and to the second terminal. Then, formation is of an adaptation scheme as a function of the set of context information. Next, adaptation is of the data stream by the first terminal as a function of the adaptation scheme. Lastly, transmission is of the adapted data stream by the first terminal to the second terminal.
