Embodiment Construction

[0059] In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0060] The development and deployment of satellite networks make up for the disadvantages of traditional terrestrial networks that have wired coverage and high development and construction costs. The construction of a space-ground integrated network that integrates satellite networks is an important part of future networks. The satellite communication network uses satellites as relay stations to forward microwave signals, and communicates between multiple ground stations to achieve "gapless" coverage on the ground. In order to improve the routing capability between satellites, an embodiment of the present application provides a satellite network routing method, which can be applied to figure 1 shown in the context of an implementation of ...

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...
