Obviously, the drawings in the following description are only some embodiments of the present invention.

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0046] The core of the present invention is to provide a data transmission method, device and medium based on high-throughput satellite communication, which can avoid network congestion, blockage and packet loss during the transmission process and improve the network security environment of the transmission.

[0047] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0048] It should be noted that for the data transmission method based on high-throughput satellite provided by the present invention, it studies how the UAV platform dynamically allocates and uses the link quality in real time when using high-throughput satellite communication, and how the UAV platform dynamically allocates and uses it when the link communication link bandwidth changes accordingly; when the UAV platform uses high-throughput satellite communication, it configures the layer 2 or layer 3 network according to the requirements of multiple service payloads to achieve multi-path distribution of multiple service payloads. Large UAV platforms generally carry multiple service payloads, and different service payloads have different requirements for links and networks. Existing UAV satellite communications cannot customize the distribution path online according to the payload requirements, but only transmit according to the pre-set path. If the data of the service payload data changes, it still needs to follow the pre-set path, resulting in the inability to fully utilize the bandwidth.

[0049] Figure 1 A flowchart of a data transmission method based on a high-throughput satellite provided by an embodiment of the present invention, as Figure 1 shown, the method includes:

[0050] S11: Obtain the signals fed back by the carrier receiver and the task requirements of each service payload;

[0051] S12: Determine the current rate based on the signals, and adjust the priority order of each service payload according to each task requirement and the current rate;

[0052] S13: Provide corresponding bandwidth resources for each service payload according to the adjusted priority order to complete data transmission.

[0053] It can be understood that obtaining the signals fed back by the carrier receiver requires dynamically monitoring the signal quality fed back by the carrier receiver. Correspondingly, the obtaining method and frequency are not limited and can be set according to the actual situation. Send a certain signal to the airborne platform terminal through the high-throughput satellite, and the airborne platform terminal then replies with the response data value of the signal to the high-throughput satellite. The feedback process is all sent by the carrier receiver. Obtain the task requirements of each service payload. Specifically, the task requirements are the relevant information of data transmission corresponding to each service payload of the current airborne platform terminal, such as specific data types (video data, image data, or base station data, etc.), the size of its data transmission, the bandwidth it can bear, etc.

[0054] Determine the current rate based on the signals. Preset the mapping relationship between signal quality and rate, determine the current rate according to the obtained current signal, and then send the current rate to the module unit for adjustment. Adjust the priority order of each service according to each task requirement and the current rate. Correspondingly, adjust the priority order of each service payload to ensure that the current data can be transmitted under the condition of sufficient bandwidth.

[0055] As an embodiment, adjusting the priority order of each service payload according to each task requirement and the current rate includes:

[0056] Judge whether the current rate is less than the threshold;

[0057] If so, determine the current priority order of each service payload according to each task requirement.

[0058] Specifically, judge whether the current rate is less than the threshold. If so, it is determined that the current satellite communication signal quality is poor and the rate is limited, and there may be a situation of service transmission congestion. Therefore, it is necessary to determine and adjust the current priority order of each service payload according to the current service requirements. For example, the service requirement for the transmission bandwidth of video data is 8M, which is also the data with relatively large bandwidth requirements at each current port. Therefore, the service payload for video data transmission is regarded as a transmission task with a higher priority.

[0059] As an embodiment, determining the current priority order of each service payload according to each task requirement includes:

[0060] Obtain the port information of each service payload according to each task requirement;

[0061] Configure the corresponding bandwidth ratio for each port information;

[0062] Transmit the data stream of the service payload according to the port corresponding to the configured bandwidth ratio;

[0063] Map the data stream into the priority queue to adjust and determine the current priority order.

[0064] Figure 2 It is a schematic diagram of data transmission provided by an embodiment of the present invention. As Figure 2 shown, multiple ports are set in the high-throughput satellite, which can meet the usage requirements of multiple airborne services. At the same time, the weight balance configuration of the bandwidth is performed for each port. When the bandwidth is sufficient, the message data is transmitted according to the configured ratio. It is necessary to obtain the port information of each service payload according to the requirements of each task, configure the corresponding bandwidth ratio for each port information, that is, the weight balance configuration of the bandwidth, and then transmit the data stream of the service payload according to the port corresponding to the configured bandwidth ratio. It should be noted that the bandwidth ratio can be adjusted and configured at any time according to the task requirements of the current service payload to ensure the sufficiency of the bandwidth.

[0065] Map the determined data stream into the priority queue to adjust the current priority order, and map the data stream of the input end data to the priority sending queue. In this embodiment, two places are used for priority configuration. The first is to schedule the corresponding bandwidth at the port, and the second is to map the data stream corresponding to the port into the priority queue. When there is congestion in the egress network, the data transmission of the high-priority queue is guaranteed first to ensure that the high-priority applications will not be delayed and blocked.

[0066] As an embodiment, mapping the data stream into the priority queue includes:

[0067] Perform Qos marking on the data stream;

[0068] Map the marked data stream into the priority queue through DSCP marking.

[0069] During the mapping process, in order to facilitate the identification of the data stream, Quality of Service (Qos) marking is performed on the data stream. In the case of limited bandwidth, QoS applies a "guaranteed" strategy to manage network traffic and enables different traffic to obtain different priority services. There are two ways to mark Qos; one is to re-mark based on the priority parameter carried by the message itself through the mapping strategy with the local priority; the other is to perform class-based data matching and marking through the flow policy (Modular QoS Command-line, MQC) tool.

[0070] It can be understood that other methods can also be used to mark the data stream. This embodiment is only a preferred embodiment. The marked data stream is mapped to the priority queue through the Differentiated Services CodePoint (DSCP). It uses the 6 used bits and the unused 2 bits in the Type of Service (TOS) identification byte of each Internet Protocol (IP) header to distinguish priorities through the encoded value.

[0071] In step S13, corresponding bandwidth resources are provided for each service payload according to the adjusted priority order to complete the current data transmission. The service data enters the cache queue. According to the control command, the priorities of different payload services are adjusted in real time. Dedicated bandwidth is preferentially provided for specific services with high priorities to support the real-time services of specific payload data. By effectively managing the bandwidth, the packet loss rate can be reduced (when the cache is large enough, packet loss can be guaranteed not to occur), and the data transmission flow can be regulated. The QoS technology cannot create bandwidth, but it can make the allocation of bandwidth more reasonable.

[0072] As an embodiment, providing corresponding bandwidth resources for each service payload according to the adjusted priority order includes:

[0073] Obtaining the exclusive bandwidth value corresponding to the bandwidth resource;

[0074] Using the exclusive bandwidth value for the service payload with the highest priority in the priority order to perform corresponding data transmission.

[0075] Specifically, obtaining the exclusive bandwidth value of the bandwidth resource and using the exclusive bandwidth value for the service payload with the highest priority in the priority order to avoid packet loss and ensure the rationality of bandwidth allocation.

[0076] A data transmission method based on a high-throughput satellite provided by an embodiment of the present invention includes: obtaining the signals fed back by the carrier receiver and the task requirements of each service payload; determining the current rate according to the signals, and adjusting the priority order of each service payload according to each task requirement and the current rate; providing corresponding bandwidth resources for each service payload according to the adjusted priority order to complete the data transmission. This method determines the corresponding current rate according to the change of the signal quality of the high-throughput satellite link, and adjusts the priority order of the service payloads at any time according to the change of the current rate and the task requirements, so as to dynamically allocate the bandwidth and network resources of the link. By adjusting the priority order, the service payloads can adapt to the network characteristics, avoid network congestion, blockage and packet loss phenomena during the transmission process, and improve the network security environment of the transmission.

[0077] Based on the above embodiments, when the current rate is greater than or equal to the threshold, the method further includes:

[0078] Obtaining the priority order of each service payload last time;

[0079] Providing corresponding bandwidth resources for each service payload according to the priority order of each service payload last time.

[0080] When the current rate is greater than or equal to the threshold, it indicates that the current signal quality is good, the rate is large, and there is no congestion in service transmission. The current bandwidth does not need to be adjusted, and its priority order does not need to be adjusted either. Just keep the current priority order, that is, the bandwidth resources corresponding to the priority order of the service payload last time.

[0081] When the current rate is greater than or equal to the threshold provided by the embodiments of the present invention, maintaining the priority order of each service payload last time to provide corresponding bandwidth resources can save adjustment resources and avoid resource consumption.

[0082] Based on the above embodiments, the method further includes:

[0083] Implementing uplink and downlink data transmission through the MSTP line and OSPF routing to perform three-layer data exchange.

[0084] It should be noted that in the above embodiments, only dynamic adjustment is performed from the link aspect. Generally, service payloads can only perform data transmission according to the existing network architecture and cannot switch between layer 2 and layer 3. This embodiment realizes three-layer switching as the user gateway between the modem and multiple airborne devices. The uplink is connected to the modem through a Multi-Service Transport Platform (MSTP) line, and the downlink controls the service diversion of multiple airborne devices through the Open Shortest Path First (OSPF) routing method. When link congestion occurs, deploy the Qos bandwidth policy to ensure key services, and send instructions to configure different networks according to the network requirements of each task to complete the allocation of network resources.

[0085] The two-layer network only has a core layer and an access layer. Such a network structure mode is easy to operate, and the switch forwards data packets according to the Media Access Control (MAC) address table. If there is a MAC address for forwarding, and if there is no MAC address, flooding is performed, that is, the data packet is broadcast to all ports. If the destination terminal receives and gives a response, then the switch can add the MAC address to the address table. This is the process of the switch establishing the MAC address.

[0086] A layer-2 network can achieve communication only through MAC addressing, but only within the same collision domain; a layer-3 network requires IP routing to achieve cross-segment communication and can span multiple collision domains. A layer-3 switch can replace a router to a certain extent, but it should be clearly recognized that the most important purpose of the emergence of a layer-3 switch is to accelerate data exchange within a large local area network.

[0087] The embodiment of the present invention provides a method for realizing uplink and downlink data transmission through an MSTP line and an OSPF route for layer-3 data exchange, which makes full use of satellite communication bandwidth, solves layer-2, layer-3 and multi-address distribution, and completes the allocation of network resources.
