Satellite network routing method, device, equipment, system and readable storage medium

Abstract

The invention discloses a satellite network routing method, device and equipment and a readable storage medium, and relates to the technical field of communication. According to the method, address information corresponding to a domain name address of a service party is obtained from a domain name system server, and a first message carrying an address of a ground station connected with the service party and orbit number information and running direction information of a satellite accessed to the ground station is sent to the service party; therefore, when the first message is forwarded in the inter-satellite route, the first message can access the running direction information of the satellite according to the ground station connected with the service party, the inter-satellite link information transmission distance is reduced, the communication overhead is saved, and the problem of packet loss caused by different orbit running directions is avoided; according to the method, the block information embedded in the address of the ground station connected with the service party and the orbit number information of the satellite accessed to the ground station connected with the service party are combined, so that the high efficiency of determining the landing satellite is realized, the detour problem in the forwarding process is avoided, and the inter-satellite routing capability in a space-ground integrated network communication scene is improved.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a satellite network routing method, apparatus, device, system, and readable storage medium. Background technique [0002] With the rapid development of space information technology, a new network system composed of satellites running in orbit through inter-satellite links has become a new global communication model. The dynamic nature of satellite network topology results in that traditional network transmission protocols cannot be directly applied to satellite networks. As the core of satellite network communication protocols, satellite network routing technology determines the overall performance of satellite networks. [0003] In the related art, greedy perimeter stateless routing (GPSR) is a location-based satellite network routing protocol. The GPSR protocol uses beacon broadcasting to spread location information. Each network node periodically broad...

Problems solved by technology

[0004] However, in the process of forwarding data using the GPSR routing protocol, when multiple next-hop nodes of a node are at the same distance from node D, the optimal next-hop cannot be directly selected, resulting in detours in data forwarding.

Moreover, when a node is inconsistent with the selected next-hop node, the connection cannot be established, and the data cannot be forwarded directly, resulting in data loss
