Abstract

A method is performed in a system integration unit located on the vessel and coupled with a radio device and a plurality of satellite transceivers that each provide a transport route for communication. A method for routing data packets from vessel to a fixed communication center through to one of the transport routes. The method determines which transport route should be used to communicate the data packet based on the availability of all transport routes and the desirability of using each transport route for the transmission of the data packet. The method then routes the data packet to the most desirable transport route that is available for communication data packets.
