Abstract
A method and apparatus encompasses a technique for routing an information packet through a satellite communications system 20 from a source satellite 38 to a destination satellite 40. A path through the system 20 is chosen for the packet and an identifier identifying the path is appended to the packet. In addition, an identifier identifying the destination satellite 40 is appended to the packet. Satellites in the system 20 then use the identifiers in the packet to route the packet to the destination satellite 40. If the chosen path is not available, an alternate path can be taken by the packet. In one embodiment of the present invention, a centralized controller 36 is provided for controlling the routing of packets throughout the entire system 20.
