Abstract

The invention discloses a unicast addressing conversion method suitable for a space-based network, and aims to solve the problems of routing security, mobility, expansibility and the like during large-scale user networking of the space-based network. According to the method, conversion information of user addressing identifiers and satellite network addressing identifiers is generated by maintaining the mapping relation between addressing identifiers of user subnets of the whole network and addressing identifiers in a satellite network, conversion of user addressing modes is completed at edge nodes of the satellite network, and user data is forwarded in the satellite network according to the satellite addressing identifiers. According to the scheme, the isolation of the user subnet routing information and the routing information in the satellite network is realized, the user carries out routing exchange in the ground subnet according to a standard addressing mode, routing is carried out in the space-based network based on the satellite addressing identifier, and the problems of routing safety, mobility and the like caused by the fact that the space-based network adopts a traditional IP network technology are solved. Meanwhile, the on-satellite processing burden of the space-based network is reduced, and large-scale user networking of the space-based network is supported.

Description

technical field [0001] The invention relates to the technical field of space-ground integrated network communication, in particular to a unicast address conversion method suitable for space-based networks. Background technique [0002] The space-ground integrated network is an information network composed of satellites with different orbits, types and characteristics, constellations and corresponding ground infrastructure. They are connected together through inter-satellite and satellite-ground links. According to the different functions of satellite nodes, they can be divided into It is space-based network, space-based access network and ground node network. The space-based network mainly adopts layered deployment of multi-functional satellites or ground gateway stations distributed on different orbital planes such as GEO, IGSO or HEO to achieve global seamless coverage. It is mainly used for the extension and expansion of the ground network and can provide ground network ...
