Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative work belong to the protection scope of the present invention.
The core of the invention is to provide a data transmission method, a device and a medium based on high-throughput satellite communication, which avoid the phenomena of network congestion, blockage and packet loss in the transmission process and improve the network security environment of transmission.
In order that those skilled in the art will better understand the disclosure, reference will now be made in detail to the embodiments of the disclosure as illustrated in the accompanying drawings.
The data transmission method based on the high-throughput satellite provided by the invention researches how the link quality changes in real time when the unmanned aerial vehicle platform uses the high-throughput satellite, and the unmanned aerial vehicle platform dynamically allocates and uses the link communication link bandwidth under the condition that the link communication link bandwidth changes; when the unmanned aerial vehicle platform uses the high-flux satellite communication, the layer two or layer three network is configured according to various service load requirements to realize multi-path distribution of various service loads. The large unmanned aerial vehicle platform generally carries multiple service loads, the requirements of different service loads on a link and a network are different, the existing unmanned aerial vehicle satellite communication cannot customize a distribution path on line according to the requirements of the loads, only transmission is carried out through a preset path, and if data of service load data change, the bandwidth still needs to be preset according to the preset path, so that the bandwidth cannot be fully utilized.
Fig. 1 is a flowchart of a high throughput satellite-based data transmission method according to an embodiment of the present invention, and as shown in fig. 1, the method includes:
s11: acquiring a signal fed back by a carrier receiver and task requirements of each service load;
s12: determining the current rate according to the signals, and adjusting the priority order of each service load according to the task requirements and the current rate;
s13: and providing corresponding bandwidth resources for each service load according to the adjusted priority order to finish data transmission.
It can be understood that, acquiring the signal fed back by the carrier receiver requires dynamically monitoring the signal quality fed back by the carrier receiver, and the corresponding acquisition mode and frequency are not limited and can be set according to actual conditions. The high-flux satellite sends a certain signal to the airborne platform end, the airborne platform end replies a response data value high-flux satellite of the signal, and the feedback process is sent by the carrier receiver. The task requirements of each service load are obtained, specifically, the task requirements are related information of data transmission corresponding to each service load of the current airborne platform end, for example, specific data types (video data, image data, base station data, or the like), data transmission sizes, borne bandwidths, and the like.
Determining the current rate according to the signal, presetting the mapping relation between the signal quality and the rate, determining the current rate according to the obtained current signal, and then sending the current rate to a module unit for adjustment. And adjusting the priority sequence of each service according to the task requirements and the current rate. Correspondingly, the priority order of each traffic load is adjusted to ensure that the current data can be transmitted under the condition of sufficient bandwidth.
As an embodiment, the adjusting the priority order of the service loads according to the task demands and the current rate includes:
judging whether the current speed is smaller than a threshold value;
and if so, determining the current priority order of each service load according to the task requirements.
Specifically, whether the current rate is smaller than the threshold value or not is judged, and if yes, it is determined that the current satellite communication signal quality is poor, the rate is limited, and a traffic transmission congestion situation may occur. Therefore, the current priority order of each service load needs to be determined and adjusted according to the current service requirements. For example, the service requirement is that the transmission bandwidth of video data needs 8M, and is also the data with more bandwidth requirements of each port at present, so the transmission service load of video data is used as a transmission task with higher priority.
As an embodiment, determining the current priority order of each traffic load according to each task requirement includes:
acquiring port information of each service load according to each task requirement;
configuring corresponding bandwidth proportion for each port information;
transmitting the data stream of the service load according to the port corresponding to the configured bandwidth proportion;
the data streams are mapped into a priority queue to adjust the current priority order.
Fig. 2 is a schematic diagram of data transmission provided in an embodiment of the present invention, and as shown in fig. 2, a plurality of ports are provided in a high-throughput satellite, so that the usage requirements of a plurality of airborne services can be met, and at the same time, each port is configured with a balanced weight of bandwidth, and message data is transmitted according to the configured ratio under the condition of sufficient bandwidth. Port information of each service load needs to be acquired according to each task requirement, corresponding bandwidth proportion is configured for each port information, namely, weight balance configuration of the bandwidth is performed, and then data streams of the service load are transmitted according to the ports corresponding to the configured bandwidth proportion. It should be noted that the bandwidth ratio can be adjusted and configured at any time according to the task requirement of the current service load, so as to ensure the sufficiency of the bandwidth.
And mapping the data flow of the input end data to a sending queue of the priority according to the determined data flow to the priority queue to adjust the current priority sequence. In this embodiment, two locations are used for priority configuration, where the first location schedules a corresponding bandwidth at a port, and the second location maps a data stream corresponding to the port into a priority queue. When the exit network is congested, the data transmission of the high-priority queue is preferentially ensured, and the high-priority application is ensured not to be delayed or blocked.
As an embodiment, mapping the data flow into the priority queue includes:
performing Qos marking on the data flow;
and mapping the marked data stream into the priority queue through the DSCP mark.
In the mapping process, in order to facilitate identification of the data flow, the data flow is subjected to Quality of Service (Qos) marking. Under the condition that the bandwidth of QoS is limited, the technology applies a 'guaranteed' strategy to manage network traffic, and different traffic can obtain different priority services. The Qos is marked in 2 ways; firstly, based on the priority parameter carried by the message, the message is re-marked through a mapping strategy with local priority; and secondly, performing class-based data matching and marking through a flow strategy (MQC) tool.
It is understood that the data stream marking process may be marked in other ways, and this embodiment is only a preferred embodiment. The marked data stream is mapped to the priority queue through Differentiated Services Code Point (DSCP) marking. It prioritizes by an encoding value using used 6 bits and unused 2 bits in a Service class of Service (TOS) flag byte of each packet network Protocol (IP) header.
In step S13, corresponding bandwidth resources are provided for each service load according to the adjusted priority order to complete the current data transmission. And the service data enters a cache queue, the priorities of different load services are adjusted in real time according to the control command, a special bandwidth is preferentially provided for the specific service with high priority, and the real-time service of the specific load data is supported. By effectively managing the bandwidth, the packet loss rate of the message can be reduced (when the cache is large enough, no packet loss can be guaranteed), and the data transmission flow can be regulated and controlled. The Qos technology cannot create bandwidth, and the bandwidth allocation can be more reasonable.
As an embodiment, providing corresponding bandwidth resources for each service load according to the adjusted priority order includes:
acquiring an exclusive bandwidth value corresponding to a bandwidth resource;
and using the dedicated bandwidth value for the service load with the highest priority in the priority order to perform corresponding data transmission.
Specifically, an exclusive bandwidth value of the bandwidth resource is obtained, and the exclusive bandwidth value is used for a service load with the highest priority in the priority order to avoid packet loss and rationality of bandwidth allocation.
The data transmission method based on the high-throughput satellite provided by the embodiment of the invention comprises the following steps: acquiring a signal fed back by a carrier receiver and task requirements of each service load; determining the current rate according to the signals, and adjusting the priority order of each service load according to the task requirements and the current rate; and providing corresponding bandwidth resources for each service load according to the adjusted priority order to finish data transmission. The 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 load at any time according to the change of the current rate and the task requirement so as to realize the dynamic allocation of the bandwidth and the network resource of the link. By adjusting the priority sequence, the service load adapts to the network characteristics, the phenomena of network congestion, network blockage and packet loss in the transmission process are avoided, and the network security environment of transmission is improved.
On the basis of the above embodiment, when the current rate is greater than or equal to the threshold, the method further includes:
acquiring the priority sequence of each service load at the last time;
and providing corresponding bandwidth resources for each service load according to the priority sequence of each service load at the last time.
When the current rate is greater than or equal to the threshold, it indicates that the current signal quality is better, the rate is higher, no congestion occurs in service transmission, the current bandwidth does not need to be adjusted, the priority order of the current bandwidth does not need to be adjusted, and the current priority order is maintained, that is, the bandwidth resources corresponding to the priority order of the last service load.
When the current rate provided by the embodiment of the invention is greater than or equal to the threshold, the priority order of each service load at the last time is kept to provide the corresponding bandwidth resource, so that the adjustment resource can be saved, and the consumption of the resource is avoided.
On the basis of the above embodiment, the method further includes:
and the uplink and downlink data transmission is realized through the MSTP line and the OSPF route so as to carry out three-layer data exchange.
It should be noted that, in the above embodiment, only the dynamic adjustment is performed from the link side, and the general traffic load can only perform data transmission according to the existing network architecture, and cannot switch between layer two and layer three. In this embodiment, three-layer switching is implemented as a user gateway between a modem and a plurality of airborne devices, an uplink is connected to the modem through a Multi-Service Transport Platform (MSTP) line, and a downlink is controlled through an Open Shortest Path First (OSPF) routing manner to implement traffic splitting of the plurality of airborne devices. When link congestion occurs, a Qos bandwidth strategy is deployed to realize the guarantee of key services, and according to the network requirements of each task, an instruction is sent to configure different networks to complete the allocation of network resources.
The two-layer network only has a core layer and an access layer. Such a network structure mode is simple and convenient to operate, and the switch forwards a data packet according to a Media Access Control (MAC) address table. If there is a MAC address for forwarding and there is no MAC address for flooding, that is, the data packet is broadcast and sent to all ports, and if the destination terminal receives the response, the switch can add the MAC address to the address table, which is a process for establishing the MAC address by the switch.
The two-layer network can realize communication only through MAC addressing, but only in the same conflict domain; the three-layer network needs to realize communication across network segments through IP routing, and can span multiple conflict domains. To some extent, three-tier switches may replace routers, but it should be consciously recognized that the most important purpose of the emergence of three-tier switches is to expedite data switching within large local area networks.
The embodiment of the invention realizes the uplink and downlink data transmission through the MSTP line and the OSPF route so as to exchange three-layer data, fully utilizes the satellite communication bandwidth, solves the problem of layer two, layer three and multi-address distribution and completes the distribution of network resources.
