A satellite system for realizing a space-based Internet network, the system comprising: a plurality of satellites configured and arranged to form a multihop communication network, an individual satellite comprising one or more inter-satellite communication modules for providing direct satellite-to-satellite bidirectional communication in forming the multihop communication network; and a plurality of physical servers (151-157, 251, 351-359, 451-453, 551-555) distributed over the plurality of satellites, the plurality of physical servers (151-157, 251, 351-359, 451-453, 551-555) being implemented with the Internet protocol suite, all individual physical servers in the plurality of physical servers (151-157, 251, 351-359, 451-453, 551-555) being networked together to form the space-based Internet network and being mutually communicable via the multihop communication network; characterised by further comprising a plurality of Border Gateway Protocol routers (150, 250, 350, 450, 550) integrated to the space-based Internet network, wherein the individual satellite is installed with a respective BGP router configured to locally manage packet routing among respective one or more physical servers installed in the individual satellite such that data packets generated by the respective one or more physical servers are transmitted from the respective one or more physical servers to the respective BGP router entirely over an in-satellite local area network for carrying out routing of the data packets, thereby lessening a communication burden on direct satellite-to-satellite bidirectional communication for the plurality of satellites and enabling the space-based Internet network to route TCP/IP traffics without requiring supports from a terrestrial Internet network. a plurality of satellites configured and arranged to form a multihop communication network, an individual satellite comprising one or more inter-satellite communication modules for providing direct satellite-to-satellite bidirectional communication in forming the multihop communication network; and a plurality of physical servers (151-157, 251, 351-359, 451-453, 551-555) distributed over the plurality of satellites, the plurality of physical servers (151-157, 251, 351-359, 451-453, 551-555) being implemented with the Internet protocol suite, all individual physical servers in the plurality of physical servers (151-157, 251, 351-359, 451-453, 551-555) being networked together to form the space-based Internet network and being mutually communicable via the multihop communication network; characterised by further comprising a plurality of Border Gateway Protocol routers (150, 250, 350, 450, 550) integrated to the space-based Internet network, wherein the individual satellite is installed with a respective BGP router configured to locally manage packet routing among respective one or more physical servers installed in the individual satellite such that data packets generated by the respective one or more physical servers are transmitted from the respective one or more physical servers to the respective BGP router entirely over an in-satellite local area network for carrying out routing of the data packets, thereby lessening a communication burden on direct satellite-to-satellite bidirectional communication for the plurality of satellites and enabling the space-based Internet network to route TCP/IP traffics without requiring supports from a terrestrial Internet network.
