Patent ID: 8132249

Claim:
Method of establishing a multi-link connection between a local communication network through digital data packets, said local communication network comprising a multi-link modem, and a remote network, said remote network comprising a multi-link gateway, wherein the method comprises the following steps: opening of a connection for each interface of the multi-link modem with the remote network; establishing of a control link over any of said opened connections, said control link being dedicated to exchanges between the multi-link modem and the multi-link gateway, for controlling the function of the multi-link connection through transmission of information shared over said control link between said multi-link modem and said multi-link gateway to a dynamic switching module for choosing a tunnel used for relaying packets, said control link being established between said multi-link modem and said multi-link gateway, for each of the connections thus opened, establishment of a corresponding communication tunnel between the multi-link modem and said multi-link gateway using the said connections, and for each digital data packet exchanged between the local network and the remote network, both through the modem as well as the gateway, a choice of the tunnel used for routing the packet in a transparent manner for the applications using the multi-link connection, said choice being based on said information shared between said multi-link modem and said multi-link gateway over said control link.
