A method routes data packets between nodes in a satellite-based communication system based on header information contained in each of the packets. The header information which contains routing and overhead information indicates whether the packet header has been received without any errors and whether the payload is to be read and processed by the node currently servicing the packet or passed on to another adjacent node. This method works in systems that have packet delays or transmission impairments, such as satellite-based telecommunication systems.

Inter-satellite method for routing packets

A method (50) reconstructs messages from segments (30) which are received in an unknown order and at different times. Each segment (30) comprises a header (31) and payload information (38). The method (50) reconstructs messages from the received segments (30) by reassembling the order as specified in the header (31) of the segment (30). Once the message is reconstructed, the message is delivered. This method (50) is especially important in satellite-based communications where no guarantee exists that the messages will be received in a sequential order or at a specified time.
