As shown in fig. 2, the server 20 includes a processor 201, a memory 202, a network interface 203, and the like.
The processor 201 is a core component of the server 20, and the processor 201 is configured to run an operating system of the server 20 and application programs (including a system application program and a third-party application program) on the server 20, so as to implement the method for determining the transmission path by the server 20.

Optionally, the processor 201 of the server 20 includes one or more CPUs, which are single-core CPUs (single-CPUs) or multi-core CPUs (multi-CPUs).
The memory 202 includes, but is not limited to, a Random Access Memory (RAM), a Read Only Memory (ROM), an erasable programmable read-only memory (EPROM), a flash memory, an optical memory, or the like. The memory 202 holds the code for the operating system.

In the case where the processor 201 implements the determination method of the transmission path provided by the embodiment of the present invention by reading the memory for storage, the memory stores therein instructions for implementing the determination method of the transmission path provided by the embodiment of the present invention.

The at least one processor 201 further executes the method described in the embodiment of the present invention according to the service requirement information of the target service stored in the memory 202. For more details of the above functions implemented by the processor 201, reference is made to the following description of various method embodiments.

Output devices include, but are not limited to, a display, a printer, and the like.
The method, the device, the server and the storage medium for determining the transmission path provided by the embodiment of the invention can be applied to a scene that a user terminal acquires service data. When the network management device obtains the service requirement information of the target service, a target transmission path for transmitting the target service data can be determined. Further, the user terminal may obtain the target service data based on the target transmission path.
With reference to the communication system shown in fig. 1, as shown in fig. 3, the method for determining a transmission path according to an embodiment of the present invention may include S101 to S103:
s101, the network management equipment acquires service requirement information of the target service.
Wherein the service requirement information includes at least one of a target bandwidth, a target latency and a target stability.
It should be understood that the target bandwidth is a required bandwidth of the user terminal for the target service, and the required bandwidth may be a minimum bandwidth for the user terminal to effectively receive the target service data. The target time delay is the time delay required by the user terminal for the target service, that is, the maximum time delay required by the user terminal for receiving the target service data.
In an implementation manner of the embodiment of the present invention, the target stability may be judged based on a packet loss rate of the target service data. That is, when the packet loss rate of the target service data is higher, it indicates that the target stability is lower; conversely, when the packet loss rate of the target service data is lower, it indicates that the target stability is higher. When the target stability is higher, it indicates that the user terminal needs to receive the target service data based on a lower packet loss rate.
In the embodiment of the invention, the service requirement information acquired by the network management equipment is sent by the terminal. Specifically, the process that the terminal sends the service requirement information and the network management device receives the service requirement information may include steps 1 to 6:
step 1, the user terminal sends the service requirement information of the target service.
And step 2, the base station receives the service requirement information sent by the user terminal and sends the service requirement information to certain user station equipment.
And step 3, the user station equipment receives the service requirement information sent by the base station and sends the service requirement information to corresponding satellite equipment (namely, the satellite equipment which has a connection relation with the user station equipment).
And step 4, the satellite device receives the service requirement information sent by the user station device, and sends the service requirement information to the corresponding gateway station device (namely, the gateway station device which has a connection relation with the satellite device).
And 5, the gateway station equipment receives the service requirement information sent by the satellite equipment and sends the service requirement information to network management equipment.
And 6, the network management equipment receives the service requirement information sent by the gateway station equipment.
Alternatively, the subscriber station apparatus and the gateway station apparatus in the embodiment of the present invention may be ground apparatuses.
S102, the network management equipment determines at least one candidate transmission path meeting the service requirement information in the network.
It should be understood that a plurality of transmission paths may be included in the network, and the network management device may determine at least one transmission path that satisfies the traffic demand information from among the plurality of transmission paths, and determine the at least one transmission path that satisfies the traffic demand information as a candidate transmission path.
With reference to fig. 3, as shown in fig. 4, the determining, by the network management device, at least one candidate transmission path specifically includes S1021-S1022:
s1021, the network management device determines the resource state information of each of a plurality of transmission paths included in the network.
The resource state information of a transmission path includes a connection state corresponding to the transmission path and a remaining bandwidth corresponding to the transmission path.
Specifically, the connection state corresponding to one transmission path includes two states, i.e., a connection success state and a connection failure state.
S1022, when the connection status corresponding to the first transmission path is that the connection is successful and the remaining bandwidth corresponding to the first transmission path is greater than or equal to the target bandwidth, the network management device determines the first transmission path as a candidate transmission path.
It should be understood that the connection status of the first transmission path indicates that the first transmission path is clear if the connection is successful. The remaining bandwidth corresponding to the first transmission path is greater than or equal to the target bandwidth, which indicates that the remaining bandwidth corresponding to the first transmission path can meet the minimum bandwidth for transmitting the target service data (i.e., meet the required bandwidth).
In the embodiment of the present invention, when a certain transmission path (for example, a first transmission path) is clear and the remaining bandwidth of the transmission path satisfies the required bandwidth, the network management device may determine the transmission path as a candidate transmission path. Each candidate transmission path can be accurately determined, and the determination efficiency of the candidate transmission paths is improved.
In an implementation manner of the embodiment of the present invention, when the connection status corresponding to the first transmission path is failure and/or the remaining bandwidth corresponding to the first transmission path is smaller than the target bandwidth, the network management device may determine that the first transmission path is not a candidate transmission path.
For example, table 1 below is an example of resource status information of each of 4 transmission paths (including transmission path 1, transmission path 2, transmission path 3, and transmission path 4) included in the network according to the embodiment of the present invention.
TABLE 1
| Transmission path | Connection state | Residual bandwidth (Mbps) |
| Transmission path 1 | Connection success | 100 |
| Transmission path 2 | Connection failure | 240 |
| Transmission path 3 | Connection success | 200 |
| Transmission path 4 | Connection success | 260 |
Assuming that the above target bandwidth is 200Mbps (megabits per second), the network management apparatus determines the transmission path 3 and the transmission path 4 as candidate transmission paths.
With reference to fig. 4, as shown in fig. 5, in an implementation manner of the embodiment of the present invention, one transmission path includes multiple links and one satellite device, and the network management device determines the resource state information of the first transmission path, which may specifically include S1021a-S1021 c:
s1021a, the network management device obtains connection states of the links included in the first transmission path, remaining bandwidths of the links, and remaining bandwidths of the satellite devices included in the first transmission path.
It should be understood that the network management device may obtain respective connection states of a plurality of links included in a certain transmission path (e.g., a first transmission path), and further determine a connection state corresponding to the first transmission path according to the respective connection states of the plurality of links. The network management device may further obtain remaining bandwidths of the multiple links and remaining bandwidths of the satellite devices included in the first transmission path, and determine the remaining bandwidth corresponding to the first transmission path according to the remaining bandwidths of the multiple links and the remaining bandwidths of the satellite devices included in the first transmission path.
In this embodiment of the present invention, for the first transmission path, the user station device included in the first transmission path may obtain the connection state and the remaining bandwidth of the relevant link, and send the connection state and the remaining bandwidth of the relevant link to the network management device; the gateway station equipment in the first transmission path can acquire the connection state and the residual bandwidth of a part of links and send the connection state and the residual bandwidth of the part of links to the network management equipment; the gateway station apparatus may further transmit the remaining bandwidth of the satellite apparatus included in the first transmission path to the network management apparatus; the network management device can directly acquire the connection state and the residual bandwidth of the link between the network management device and the core network device. In this way, the network management device may obtain the connection status of each of the plurality of links included in the first transmission path, the remaining bandwidth of each of the plurality of links, and the remaining bandwidth of the satellite device included in the first transmission path.
Illustratively, continuing as shown in fig. 1, assume that the first transmission path includes link (r), link (c), and link (c). The network management device 112 obtains the respective connection states and residual bandwidths of 3 links (including link (r), link (r) and link (r)) sent by the user station device 103; the network management device 112 obtains the remaining bandwidth of the satellite device 106 transmitted by the gateway station device 109; the network management device 112 obtains the connection status and the remaining bandwidth of each of the 2 links (including link r and link c) sent by the gateway station device 109; the network management device 112 directly acquires the connection status and the remaining bandwidth of the link c.
In one implementation manner of the embodiment of the present invention, the network management device may obtain configuration information and state statistical information of the subscriber station device. The configuration information includes an Internet Protocol (IP) address of the subscriber station device, port information of the subscriber station device, and a communication protocol used by the subscriber station device, and may determine whether a connection state of a link between the subscriber station device and the base station is a connection success; the state statistics information includes location information of the subscriber station apparatus, etc.
S1021b, when there is no connection failure in the connection states of the plurality of links, the network management device determines that the connection state corresponding to the first transmission path is a connection success.
It should be understood that the plurality of links are links included in the first transmission path. When the connection failure does not exist in the connection states of the plurality of links, it is indicated that the connection states of the plurality of links are connection success, that is, each link in the plurality of links is smooth. In this way, the network management device may determine that the connection status corresponding to the first transmission path is successful, that is, the first transmission path is also clear.
In an implementation manner of the embodiment of the present invention, when there is a connection failure in connection states of the plurality of links, the network management device determines that the connection state corresponding to the first transmission path is the connection failure.
For example, with reference to the example in S1021a, if the connection states of the 6 links (i.e., link (r), and link (c)) are all successful, the network management device determines that the connection state corresponding to the first transmission path is successful.
S1021c, the network management device determines the minimum value of the remaining bandwidths of the plurality of links and the remaining bandwidth of the satellite device included in the first transmission path as the remaining bandwidth corresponding to the first transmission path.
It will be appreciated that the remaining bandwidth of the link (or satellite device) is used to characterize the maximum bandwidth that the link can allocate for the target service. In the embodiment of the present invention, the network management device determines, as the remaining bandwidth corresponding to the first transmission path, the minimum value of the remaining bandwidths of the plurality of links and the remaining bandwidth of the satellite device included in the first transmission path. That is, each link and each satellite device included in the first transmission path can meet, and the maximum bandwidth allocated to the target service is determined as the remaining bandwidth corresponding to the first transmission path, so that the network management device can determine that the first transmission path can meet the transmission requirement of the target service data.
For example, in combination with the example in S1021a, it is assumed that the respective residual bandwidths of link (r), link (c), and link (c) are 150Mbps, 200Mbps, 180Mbps, 150Mbps, 220Mbps, and 200Mbps, respectively; assume again that the remaining bandwidth of satellite device 106 is 180 Mbps. The network management device determines that the remaining bandwidth corresponding to the first transmission path is 150 Mbps.
S103, the network management device determines a target transmission path from at least one candidate transmission path.
The target service transmission path is used for transmitting target service data.
It should be understood that the target service data is service data of the target service, and the user terminal may obtain the service data based on the target service transmission path.
It can be understood that, the user terminal may send a service data acquisition request message to the base station, where the service data acquisition request message includes an identifier of the target service, and the service data acquisition request message is used to request to acquire the target service data. Further, after receiving the service data request message, the core network device may determine the target service data based on the identifier of the target service, and send the target service data to the network management device. Further, the network management device receives the target service data, determines the target transmission path based on the method for determining the transmission path provided by the embodiment of the present invention, and sends the target service data to the user terminal based on the target transmission path.
According to the method for determining the transmission path provided by the embodiment of the invention, the network management equipment can acquire the service requirement information of the target service and determine at least one candidate transmission path which meets the service requirement information in the network. The at least one candidate transmission path satisfies the service requirement information of the target service, and the service requirement information can represent the requirement characteristics of the user terminal for transmitting the target service data. Therefore, the target transmission path determined by the network management device from the at least one candidate transmission path also meets the service requirement information, that is, the network management device can determine a path for transmitting the service data, which can provide effective service, for the user terminal, so that the service data can be effectively transmitted, and the user experience is improved.
With reference to fig. 3, as shown in fig. 6, in an implementation manner of the embodiment of the present invention, the determining, by the network management device, a target transmission path from at least one candidate transmission path includes S1031:
and S1031, the network management device determines the candidate transmission path with the largest corresponding residual bandwidth in the at least one candidate transmission path as the target transmission path.
It should be understood that, for a transmission path, the remaining bandwidth corresponding to the transmission path is larger, which indicates that the bandwidth that the transmission path may allocate to the target service is more sufficient, or it may be understood that the transmission performance of the transmission path is better. In this embodiment of the present invention, the network management device may select (or determine) a transmission path with the optimal transmission performance from the at least one candidate transmission path, and determine the transmission path with the optimal transmission performance as the target transmission path.
In an implementation manner of the embodiment of the present invention, the network management device may further determine, as the target transmission path, a candidate transmission path with the smallest corresponding delay in the at least one candidate transmission path.
In another implementation manner of the embodiment of the present invention, the network management device may obtain respective time delays of a plurality of links included in a certain transmission path (for example, a first transmission path) and a time delay of a satellite device included in the first transmission path, and further, the network management device may determine an average value of the respective time delays of the plurality of links and the time delay of the satellite device included in the first transmission path as the time delay corresponding to the first transmission path.
With reference to fig. 3, as shown in fig. 7, in an implementation manner of the embodiment of the present invention, the multiple transmission paths are low-rail transmission paths, the network further includes multiple high-rail transmission paths, and one high-rail transmission path includes one high-rail device, and the method for determining a transmission path according to the embodiment of the present invention further includes S104 to S105.
And S104, the network management equipment receives the control signaling sent by the core network equipment.
It should be understood that the control signaling may be a certain response message (for example, a core network device successfully responds to a service data acquisition request message sent by a network management device, and the like), may also be a certain request message (for example, the core network device requests to establish a communication connection with the network management device, and the like), and may also be a certain indication message (for example, the core network device indicates a user terminal to report a quality of experience (QoE) measurement report, and the like).
And S105, the network management equipment determines the transmission path with the maximum corresponding residual bandwidth in the plurality of high-orbit transmission paths as the transmission path corresponding to the control signaling.
In conjunction with the description of the above embodiments, it will be understood that the plurality of high-orbit transmission paths are transmission paths including high-orbit satellite devices. In this embodiment of the present invention, the network management device may determine, from the multiple high-rail transmission paths, one high-rail transmission path used for transmitting the control signaling sent by the core network device, that is, a transmission path corresponding to the control signaling.
It should be noted that, a method for determining, by the network management device, the remaining bandwidth corresponding to each of the multiple high-rail transmission paths is the same as or similar to the method for determining, by the network management device, the remaining bandwidth corresponding to the first transmission path, and details are not repeated here.
In an implementation manner of the embodiment of the present invention, the network management device may also determine, as the transmission path corresponding to the control signaling, the high-rail transmission path whose connection state is successful and whose corresponding remaining bandwidth is the largest, among the multiple high-rail transmission paths.
In another implementation manner of the embodiment of the present invention, each of the transmission paths (i.e., the low-track transmission paths) may not have any remaining resource (i.e., the remaining resource corresponding to each of the transmission paths is 0). At this time, the network management device may determine a target transmission path for transmitting the target service data from the plurality of overhead transmission paths. For example, the network management device may determine, as the target transmission path, the higher-track transmission path of the plurality of higher-track transmission paths, the corresponding connection state being successful and the corresponding remaining bandwidth being the largest.
In the embodiment of the present invention, the server and the like may be divided into functional modules according to the above method example, for example, each functional module may be divided corresponding to each function, or two or more functions may be integrated into one processing module. The integrated module can be realized in a hardware mode, and can also be realized in a software functional module mode.
