METHODS FOR TRANSMITTING AND RECEIVING DATA BETWEEN A TERMINAL AND A GATEWAY, IN PARTICULAR VIA A SATELLITE LINK

摘要

A method for transmitting data between a terminal and a gateway, the data being transported by Ethernet frames comprising an Ethernet header and a payload, which are themselves encapsulated in lower level packets each comprising a header containing a medium access address, comprises the following steps: determining contexts common to frames whose Ethernet headers have identical fields, and defining an identifier of each the context; associating all or some of the frames with the corresponding context identifiers and suppressing the fields from their Ethernet headers; and introducing the context identifier of each frame for which the fields of the Ethernet header have been suppressed from the header of the lower level packet encapsulating it by replacing its medium access address. A method for receiving data transmitted by means of such a method.

1. A method for transmitting data between a terminal and a gateway, the data being transported by Ethernet frames comprising an Ethernet header and a payload, which are encapsulated in lower level packets each comprising a header containing a medium access address indication, the method comprising the following steps:
a) determining contexts common to frames whose Ethernet headers have static fields, and defining an identifier of each said context; b) associating all or some of said frames with the corresponding context identifiers and suppressing said static fields from their Ethernet headers; and c) introducing the context identifier of each frame for which said fields of the Ethernet header have been suppressed into the header of the lower level packet encapsulating it in replacement of its medium access address indication.
