Abstract
A method for selecting a data path includes identifying a plurality of available data paths between a router device and a wide area network. Path selection data is obtained. The path selection rules are processed with the obtained path selection data. For each of a plurality of data communications to be routed, one of the plurality of available data paths is selected according to the processing of the path selection rules. Each of the plurality of data communications is routed between a local area network and the wide area network via a data exchanger and a remote link that follows the data path selected for that data communication.
