Abstract

La présente invention concerne un système servant à effectuer une communication navire-terre non basée sur TCP. La présente invention présente l'effet suivant. À savoir, la présente invention permet l'émission (Tx) ou la réception (Rx) par un équipement VDES, sans en-tête MAC ni en-tête TCP ni en-tête IP, dans une communication navire-terre, et permet ainsi de réduire non seulement le nombre de communications mais également une capacité de données.
