Problems solved by technology

The topological structure of the ground network is relatively fixed, and the connection relationship between domains is basically fixed. Using the BGP protocol in the ground network can relatively effectively ensure reliable connection between domains. However, the topology of space satellite networks changes frequently and the bit error rate is large. When using a satellite network, the dynamic connection of the space satellite network cannot be reliably realized, and it will cause frequent routing updates, communication link congestion, and waste of network resources.

Abstract

The invention provides a BGP+ based routing method between source and target terminals, and the source and target terminals are positioned in first and second autonomous systems respectively. The method comprises that S1) connection is established between the source and target terminals; S2) if the source terminal is connected with the target terminal directly, the source terminal sends data to the target terminal according to a routing table, and otherwise, the source terminal forwards the data via nodes in the first and second autonomous systems and then sends the data to the target terminalaccording to the routing table; S3) when the source terminal is disconnected from and then re-connected with the target terminal, the routing table of the source terminal is not updated if disconnection time is less than a threshold, and otherwise, changed routing information in the routing table within the disconnection time is updated; and S4) when the routing table stored in the first node hasfailure, a dynamic routing table is generated in the first node, and the first node forwards the data to the second node according to the dynamic routing table. The invention also provides a BGP+ based routing monitoring method between the source and target terminals.

Description

technical field [0001] The present disclosure relates to a routing method and a routing monitoring method between a source terminal and a destination terminal based on BGP+. Background technique [0002] With the development of communication technology, the area covered by the communication network is also expanding, and the construction of space satellite network is becoming more and more important. The space satellite network has a wide geographical coverage and flexible networking. The traditional terrestrial Internet and mobile communication network are mature in technology and rich in resources. Rich and huge business. [0003] At present, satellite networking and store-and-forward capabilities are lacking. In order to realize space networking and integrated network integration, a unified network layer design is crucial. A unified network layer can avoid the complexity and overhead caused by protocol conversion or translation, and shield the link differences from the ...
