1. A method for discovering a data routing path via satellite link to a mobile platform from a ground segment of a communications network wherein the mobile platform and the ground segment are configured to communicate via at least one of a plurality of satellite transponders, each transponder having a dedicated ground segment equipment chain, the method comprising the steps of:

  • assigning a unique path signature to each of the plurality of transponder equipment chains to uniquely identify each chain;

    multicasting, by the ground segment via at least one of the transponder equipment chains, at least one message, each message containing the path signature corresponding to the transponder equipment chain through which the message is multicast; and

    the platform transmitting, to the ground segment, at least one path signature received by the platform via the at least one message.
