  • Patent number: 7583622
    Abstract: A path control packet is sent from a router to a receiver. The receiver capsulates the received packet and transmits a capsulated IP packet to a feed via a ground line. The feed extracts the path control packet by decapsulation and transmits the packet to a router. At the same time, path control information is sent to a satellite line. The router processes the packet as if the path control information from the router reached via the satellite line. When a receiver receives a packet via the satellite line, it transmits the packet as a packet to a router. This router processes the packet as if the path control information from the router reached via the satellite line.

  • Patent number: 6741573
    Abstract: A satellite link is dynamically assigned in a communication system having a plurality of clients, each client having a unidirectional satellite receiving means and a bi-directional network communication means. Unique information of each client is stored at the managing server within a service provider. A client utilizes its network communication means to send a request to the managing server. The managing server then allocates an IP address to the client's satellite receiving means, and a satellite link is established between the client's satellite receiving means and the managing server based upon the stored unique information of the given client. The assigned IP address corresponds to the assigned satellite link, and the assigned IP address is sent from the managing server to the client utilizing the client's directional network communication means.
