A satellite system for realizing a space-based Internet network , the system comprising: a plurality of satellites (101-105) configured and arranged to form a multihop communication network , an individual satellite comprising one or more inter-satellite communication modules (181-184) 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 (101-105), 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 (BGP) routers 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 (151-157) installed in the individual satellite such that data packets generated by the respective one or more physical servers (151-157) are transmitted from the respective one or more physical servers (151-157) 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 (101-105) and enabling the space-based Internet network to route TCP/IP traffics without requiring supports from a terrestrial Internet network . a plurality of satellites (101-105) configured and arranged to form a multihop communication network , an individual satellite comprising one or more inter-satellite communication modules (181-184) 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 (101-105), 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 (BGP) routers 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 (151-157) installed in the individual satellite such that data packets generated by the respective one or more physical servers (151-157) are transmitted from the respective one or more physical servers (151-157) 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 (101-105) and enabling the space-based Internet network to route TCP/IP traffics without requiring supports from a terrestrial Internet network . <EOS>
