In recent years, in order to provide worldwide broadband Internet access services, many mega-constellation projects have been proposed. Traditional ground-based and space-based telecommand systems only rely on a single path for data transmission, which is vulnerable once the path fails. This paper utilizes inter-satellite-links (ISLs) in the constellation network to reduce the risk of data transmission failure, and proposes the failure-tolerant and low-latency redundant multi-path routing algorithm (RMPR). RMPR transmits multiple data copies on multiple shortest edge-disjoint paths according to the optimal proportions with the minimum delay. Compared with traditional single-path routing and backup multi-path routing, RMPR ensures both reliability and timeliness in telecommand system. |
