Description

Technical field

[0001] The invention relates to the technical field of data communication via satellite networks. In particular, the invention relates to a system device that transmits data packets via satellite-based and terrestrial transmission paths, taking latency parameters into account, and optimizes them system-wise. State of the art

[0002] Satellite-based communication systems are used to provide data connections in regions with limited terrestrial infrastructure or for time-critical applications. Known systems transmit data packets either exclusively via satellite links or use hybrid networks without dynamic, system-level latency optimization.

[0003] In current technology, the selection of the transmission path is often static or purely protocol-based. Known solutions do not adequately respond to time-varying latencies, particularly with fluctuating satellite connections, orbital dynamics, or load situations. Furthermore, a system-level enforcement unit that directly translates detected latency conditions into technical transmission adjustments is lacking.

[0004] Therefore, the current state of the art does not offer a system device that combines satellite-based data transmission with autonomous, latency-optimized control at the system level. Object of the invention

[0005] The object of the present invention is to provide a system device which: • Transmits data packets via satellite-based transmission paths, • Latency parameters of the available transmission paths are captured by the system, • enables a latency-optimized selection or adjustment of the transmission path, • generates technical control signals to adapt the transmission, • works independently of application software, and • ensures reliable and time-optimized data transmission. Summary of the invention

[0006] The problem is solved by a system device for satellite-based, latency-optimized transmission of data packets with the features of the claims.

[0007] The system device comprises at least one processing unit, an interface unit for coupling with at least one satellite connection and optionally at least one terrestrial network connection, a latency measurement unit, a transmission control unit and an enforcement unit.

[0008] The transmission control unit generates technical control signals on the hardware or firmware side, with which data packets are routed, buffered, prioritized or transmitted in a time-adjusted manner depending on determined latency parameters. Detailed description of the invention

[0009] The system device according to the invention is designed as an independent communication unit or as a component of a network node.

[0010] An interface unit couples the system device to at least one satellite connection, for example to geostationary, medium or low Earth orbit satellites, and optionally to at least one terrestrial network connection.

[0011] A latency monitoring unit continuously or event-driven records technical latency parameters of the available transmission paths. These latency parameters include, in particular, transmission delays, jitter, packet transit times, or comparable temporal system characteristics.

[0012] The transmission control unit evaluates the recorded latency parameters and determines a latency-optimized transmission state. Based on this evaluation, the transmission control unit generates technical control signals that are fed to the enforcement unit.

[0013] The enforcement unit translates the control signals into system-level actions, for example by: • selects or switches the transmission path for data packets, • Temporarily stores or re-sequences data packets, • Adjusts transmission priorities, or • Prefers to transmit time-critical data packets via low-latency satellite paths.

[0014] The control and enforcement take place independently of application software and user interventions and forms a closed technical rule structure in which recorded latency parameters are directly translated into transmission adjustments.

[0015] Optionally, a logging unit is provided that stores system-side information about latency conditions and implemented transmission measures.
