It should be understood that the number of terminal devices, networks and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, monitoring servers, and video servers, as desired for implementation.
With continued reference to fig. 2, a flow 200 of one embodiment of a method for information transfer for a monitoring server according to the present application is shown. The monitoring server is respectively in communication connection with the client and the video server of each warehouse in the plurality of warehouses, and the information transmission method comprises the following steps:
in step 201, in response to receiving a video acquisition request including a warehouse identifier sent by a client, the warehouse indicated by the warehouse identifier is used as a target warehouse, and current network data and preset network data of the target warehouse are queried.
In this embodiment, the electronic device (for example, the monitoring server 105 shown in fig. 1) on which the information transmission method is executed may query, in response to receiving a video acquisition request including a repository identifier sent by a client (for example, the terminal devices 101, 102, 103 shown in fig. 1), the current network data and the preset network data of the target repository by using the repository indicated by the repository identifier as the target repository. The warehouse identifier may be a character string composed of various characters (e.g., numerals, letters, symbols, etc.) for indicating and distinguishing the warehouse. It should be noted that the current network data may be various data for characterizing the current network situation of the target repository, and the current network data may include, by way of example, a current network bandwidth, an uplink traffic, a downlink traffic, a network delay duration, and the like. It should be noted that the preset network data may include various network configuration information (such as total bandwidth and the like) of the target warehouse and various thresholds (such as a network bandwidth threshold, a network delay rate threshold, a packet loss rate threshold and the like) preset by a technician.
In this embodiment, the electronic device may determine whether the current network of the target repository supports video transmission based on a comparison of the current network data and preset network data. Specifically, the electronic device may determine whether the current network of the target repository supports transmission based on a comparison of one or more data included in the current network data with corresponding one or more data in the preset network data. As an example, in response to determining that the current network bandwidth included in the current network data is less than the network bandwidth threshold included in the preset network data, it may be determined that the current network of the repository does not support video transmission; in response to determining that the current network bandwidth included in the current network data is not less than the network bandwidth threshold included in the preset network data, it may be determined that the current network of the repository supports video transmission.
In response to determining that the current network of the target repository supports video transmission, a video acquisition request is sent to a video server located at the target repository, step 203.
In this embodiment, in response to determining that the current network of the target warehouse supports video transmission, the electronic device may send the video acquisition request to a video server located in the target warehouse through a wired connection manner or a wireless connection manner. It should be noted that the wireless connection may include, but is not limited to, 3G/4G connections, wiFi connections, bluetooth connections, wiMAX connections, zigbee connections, UWB (ultrawideband) connections, and other now known or later developed wireless connection means.
In this embodiment, after the electronic device sends the video acquisition request to the video server located in the target repository, the electronic device may receive a video returned by the video server and send the video to the client.
With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of the information transmission method according to the present embodiment. In the application scenario of fig. 3, first, a user sends a video acquisition request 303 containing a repository identification to a monitoring server 302 using a client 301. Then, the monitoring server 302 uses the warehouse indicated by the warehouse identifier as a target warehouse, queries the current network data and preset network data of the target warehouse, and determines whether the current network of the target warehouse supports video transmission based on the comparison of the current network data and the preset network data. In response to determining that the current network of the target repository supports video transmission, the video acquisition request 303 is sent to a video server 304 located at the target repository. Thereafter, the video server 304 returns the video 305 to the monitoring server 303. Finally, the monitoring server 303 returns the video 305 to the client 301.
According to the method provided by the embodiment of the application, after the video acquisition request which is sent by the client and contains the warehouse identifier is received, the current network data and the preset network data of the warehouse indicated by the target warehouse identifier are queried, whether the current network of the target warehouse supports video transmission or not is determined based on the comparison of the current network data and the preset network data, the video acquisition request is sent to the corresponding video server in response to the determination that the current network of the target warehouse supports video transmission, and finally the video returned by the video server is sent to the client, so that the video transmission and access of the warehouse can be dynamically controlled based on the current network condition of the warehouse, the video flow is ensured not to influence the normal service, and the flexibility of data interaction is improved.
With further reference to fig. 4, a flow 400 of yet another embodiment of a method of information transmission is shown. The flow 400 of the information transmission method includes the following steps:
in step 401, in response to receiving a video acquisition request sent by a client and containing a warehouse identifier, the warehouse indicated by the warehouse identifier is used as a target warehouse, and the current network data and the preset network data of the target warehouse are queried.
In this embodiment, the electronic device (for example, the monitoring server 105 shown in fig. 1) on which the information transmission method is executed may query, in response to receiving a video acquisition request including a repository identifier sent by a client (for example, the terminal devices 101, 102, 103 shown in fig. 1), the current network data and the preset network data of the target repository by using the repository indicated by the repository identifier as the target repository.
It should be noted that, the current network data may include a current network delay rate and a current packet loss rate, and the preset network data may include a preset network delay rate and a preset packet loss rate. Here, the current network delay rate may be a ratio of a network delay duration in a period from a certain time to a current time to a total duration of the period. The current packet loss rate may be a ratio of the number of lost packets to the transmitted data set in the period. The preset network delay rate and the preset packet loss rate may be preset values by a technician based on a large amount of data statistics.
It should be noted that, the current network data may further include a current bandwidth usage percentage and a current concurrency request number, and the preset network data may further include a preset correspondence table between bandwidth usage percentages and concurrency request thresholds. Here, the current bandwidth usage percentage may be a ratio of a current bandwidth of the network of the target repository to a total bandwidth of the network of the target repository. The current number of concurrent requests may be a total number of video acquisition requests that are received by the electronic device and that contain a repository identification of the target repository and that are not returned to the client video data. In practice, the current concurrent request number may be increased by 1 when the electronic device receives a video acquisition request containing the warehouse identifier of the target warehouse once; the electronic device may decrease the number of current concurrent requests by 1 each time the video indicated by the video acquisition request including the repository identification of the target repository is returned to the client.
In step 402, in response to determining that the current network delay rate is greater than the preset network delay rate or the current packet loss rate is greater than the preset packet loss rate, it is determined that the current network of the target warehouse does not support video transmission.
In this embodiment, the electronic device may determine whether the current network delay rate is greater than the preset network delay rate, and determine whether the current packet loss rate is greater than the preset packet loss rate. In response to determining that the current network delay rate is greater than the preset network delay rate or the current packet loss rate is greater than the preset packet loss rate, it may be determined that the current network of the target repository does not support video transmission, after which step 405 may be performed. Step 403 may be performed in response to determining that the current network delay rate is not greater than the preset network delay rate and the current packet loss rate is not greater than the preset packet loss rate.
In this embodiment, in response to determining that the current network delay rate is not greater than the preset network delay rate and the current packet loss rate is not greater than the preset packet loss rate, the electronic device may determine a concurrency request threshold corresponding to the current bandwidth usage percentage from the correspondence table.
In response to determining that the current number of concurrent requests is greater than the determined concurrent request threshold, it is determined that the current network of the target repository does not support video transmission, step 404.
In this embodiment, the electronic device may compare the current number of concurrent requests with the determined concurrent request threshold. In response to determining that the current number of concurrent requests is greater than the determined concurrent request threshold, the electronic device may determine that the current network of the target repository does not support video transmission and perform step 405. In response to determining that the current number of concurrent requests is not greater than the determined concurrent request threshold, the electronic device may perform step 406.
In response to determining that the current network of the target repository does not support video transmission, a hint message is sent to the client that characterizes the current network congestion, step 405.
In this embodiment, in response to determining that the current network of the target warehouse does not support video transmission, the electronic device may send a prompt message for characterizing current network congestion to the client.
In response to determining that the current number of concurrent requests is not greater than the determined concurrent request threshold, a determination is made that the current network of the target repository supports video transmission, step 406.
In this embodiment, the electronic device may determine that the current network of the target repository supports video transmission in response to determining that the current number of concurrent requests is not greater than the determined concurrent request threshold.
In step 407, in response to determining that the current network of the target repository supports video transmission, a video acquisition request is sent to a video server located at the target repository.
In this embodiment, in response to determining that the current network of the target warehouse supports video transmission, the electronic device may send the video acquisition request to a video server located in the target warehouse through a wired connection manner or a wireless connection manner.
Step 408, the video returned by the video server located in the target warehouse is sent to the client.
In this embodiment, after the electronic device sends the video acquisition request to the video server located in the target repository, the electronic device may receive a video returned by the video server and send the video to the client.
As can be seen from fig. 4, compared with the embodiment corresponding to fig. 2, the flow 400 of the information transmission method in this embodiment highlights the step of determining whether the current network of the target warehouse supports video transmission based on the comparison of the current network data and the preset network data. Therefore, the scheme described in the embodiment can introduce that the current network data is compared with more data in the preset network data, so that whether the current network supports video transmission or not is more comprehensively determined, and the flexibility of data interaction is further improved.
With further reference to fig. 5, as an implementation of the method shown in the foregoing figures, the present application provides an embodiment of an information transmission apparatus, where an embodiment of the apparatus corresponds to the embodiment of the method shown in fig. 2, and the apparatus may be specifically applied to a monitoring server.

In this embodiment, the determining unit 502 may determine whether the current network of the target warehouse supports video transmission based on a comparison between the current network data and preset network data. Specifically, it may be determined whether the current network of the target repository supports transmission based on a comparison of one or more data included in the current network data with corresponding one or more data in the preset network data.
In this embodiment, in response to determining that the current network of the target warehouse supports video transmission, the first sending unit 503 may send the video acquisition request to the video server located in the target warehouse through a wired connection manner or a wireless connection manner.
