1. Method of establishing a multi-link connection between a local communication network through digital data packets and a remote network, wherein the method comprises the following steps:
- opening of a first connection between a modem connected to the local network and the remote network via a first access network,opening of at least one second connection between the said modem and the remote network via a second access network,for each of the connections thus opened, establishment of a corresponding communication tunnel between the modem and an appliance connected to the remote network called gateway using the said connection, andfor 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.

Abstract
The invention enables the different access links between a local network and a remote network to be used in a common and transparent manner. The invention is based on the use of various IP tunnels using the different access links between an appliance on the local network of the user and an appliance on the remote network. Said tunnels are embodied as a single link providing access to the remote network.
