ABSTRACT:
A method for discovering a data routing path via satellite link to a mobile platform from a ground segment of a communications network. The mobile platform and ground segment communicate via satellite transponder. Each transponder has a dedicated ground segment equipment chain. A unique path signature is assigned to each chain. The ground segment multicasts, via the chain(s), message(s) containing the path signature corresponding to the chain(s). The platform transmits, to the ground segment, path signature(s) received by the platform via the message(s). The ground segment maintains information for controlling path discovery. Thus misrouting due to differences in transponder path identification is eliminated.
