Abstract:
1. A method for the transmission of data packets in a tunnel interconnecting two sub-networks in order to form a total communications network, said tunnel being implemented between two tunnel end-points, each of said two sub-networks comprising a distinct tunnel end-point among said two tunnel end-points, said tunnel implementing at least two transmission channels, said method being implemented by one of said two tunnel end-points, known as a tunnel incoming end-point, wherein the method comprises the following steps for each data packet: a) reception of a data packet coming from a source device belonging to a same sub-network as the tunnel incoming end-point; b) selection of an effective channel from among the transmission channels, as a function of a protocol associated with the payload data contained in the received packet, and of a piece of information on quality of transport linked to current conditions of transmission on said transmission channels, said piece of information depending on said protocol associated with the payload data contained in the received packet; c) encapsulation of the received packet, according to a transport protocol associated with the effective channel, used to obtain a packet to be sent; and d) transmission of the packet to be sent in the tunnel on the effective channel selected.
