[0028] In order to make the above objectives, characteristics and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0029] Embodiments of the present application can involve a core server, a conversion server and a service layer. Referring to Figure 1 , a schematic diagram of the connection relationship between the core server, the conversion server and the service layer in the embodiments of the present application is shown. In Figure 1 , the core server includes a master control device, a plurality of sub-control devices and a plurality of terminal devices. The master control device is the brain of the core server, used for receiving and processing service instructions sent by the service layer and returning service processing results to the service layer. The sub-control devices are cascaded under the master control device, used for forwarding data. The terminal devices are physical devices or virtual devices cascaded under the sub-control devices. The service layer can be divided into a conference management service product side and a network management service product side according to different service types. The conference management service product side includes a conference management server and a conference management client, and the conference management server is connected with the terminal device and the conference management client respectively. The network management service product side includes a network management server and a network management client, and the network management server is connected with the terminal device and the network management client respectively.

[0030] The conference management server and the network management server can be collectively referred to as a product server, and the conference management client and the network management client can be collectively referred to as a product client. After the product server is connected with the terminal device, the product client can transmit service data packets to the terminal device. The terminal device encapsulates the service data packets into a transparent uplink instruction packet. The transparent uplink instruction packet carries a service request sent by the service layer to the conversion server. The transparent uplink instruction packet passes through the sub-control device and the master control device in turn and reaches the conversion server. The conversion server parses the transparent uplink instruction packet to obtain the service data packet, transmits the service data packet to the master control device, and then controls the core server to execute corresponding services to obtain service processing results by the master control device. The conversion server encapsulates the service processing results into a transparent downlink instruction packet, transmits the transparent downlink instruction packet to the terminal device through the master control device and the sub-control device in turn. The terminal device parses the transparent downlink instruction packet to obtain the service processing results, and returns the service processing results to the product client through the product server.

[0031] Referring to Figure 2 , a step flowchart of a data packet transmission method in the embodiments of the present application is shown. The method can be applied to a core server, which includes a master control device and a terminal device. The master control device is connected with a conversion server, and the terminal device is connected with a product server. The method can specifically include the following steps:

[0032] Step 201, receiving a service data packet from the product server by using the terminal device, and encapsulating the service data packet into a transparent uplink instruction packet.

[0033] In the embodiment of the present application, the product server receives the service instruction or product request of the product client. The service instruction or product request can be carried in a service data packet, sent to the product server by the product client, and forwarded to the terminal device by the product server. The terminal device has the capability of encapsulating the service data packet into a transparent uplink instruction packet.

[0034] In step 202, the transparent uplink instruction packet from the terminal device is transmitted to the switching server by the master device.

[0035] In the embodiment of the present application, the terminal device can transmit the transparent uplink instruction packet to the corresponding sub-control device, which forwards the transparent uplink instruction packet to the corresponding master device. The master device forwards the transparent uplink instruction packet to the switching server.

[0036] The switching server is a newly added server in the embodiment of the present application. The switching server is in communication connection with the core server, specifically, the switching server is in communication connection with the master device in the core server.

[0037] In step 203, the service data packet obtained by the switching server by analyzing the transparent uplink instruction packet is received by the master device, and the service processing result is obtained by performing service processing according to the service data packet.

[0038] In the embodiment of the present application, the switching server can analyze the transparent uplink instruction packet to obtain the service data packet. Then, the switching server transmits the analyzed service data packet to the core server, which performs relevant services according to the service data packet to obtain the service processing result.

[0039] In step 204, the service processing result is transmitted to the switching server by the master device.

[0040] In the embodiment of the present application, after the core server performs relevant services according to the service data packet to obtain the service processing result, the master device returns the service processing result to the switching server.

[0041] In step 205, the transparent downlink instruction packet obtained by the switching server by encapsulating the service processing result is received by the master device.

[0042] In the embodiment of the present application, after receiving the service processing result, the switching server can encapsulate the service processing result into a transparent downlink instruction packet, and transmit the transparent downlink instruction packet to the core server. Specifically, the switching server transmits the transparent downlink instruction packet to the master device of the core server.

[0043] In step 206, the service processing result is obtained by the terminal device by analyzing the transparent downlink instruction packet from the master device, and the service processing result is transmitted to the product server.

[0044] In the embodiment of the application, after the master control device receives the transparent downlink instruction package, the transparent downlink instruction package is transmitted to the corresponding sub-control device, and the sub-control device forwards the transparent downlink instruction package to the corresponding terminal device. After the terminal device receives the transparent downlink instruction package, the service processing result is obtained by analyzing the transparent downlink instruction package, and the service processing result is returned to the product server. Finally, the product server sends the service processing result to the product client. Thus, the entire product service execution from the product client issuing a service instruction or product request to the product client receiving the service processing result is completed.

[0045] The transmission scheme of the data package provided by the embodiment of the application involves a core server, a switching server and a product server, wherein the core server includes a master control device and a terminal device, the master control device is connected with the switching server, and the terminal device is connected with the product server. The product server can send a service data package to the terminal device, and then encapsulate the service data package into a transparent uplink instruction package by using the terminal device, and transmit the transparent uplink instruction package to the master control device. The master control device transmits the transparent uplink instruction package to the switching server. The switching server analyzes the service data package from the transparent uplink instruction package, and transmits the service data package to the master terminal, and then the master terminal performs corresponding service processing according to the service data package to obtain a service processing result, and transmits the service processing result to the switching server. The switching server encapsulates the service processing result into a transparent downlink instruction package, and transmits the transparent downlink instruction package to the master control device. After the master control device transmits the transparent downlink instruction package to the terminal device, the terminal device analyzes the service processing result from the transparent downlink instruction package, and transmits the service processing result to the product server. Thus, the execution flow of the entire product service that the product server issues a service data package to the terminal device of the core server and receives the service processing result from the terminal device is realized.

[0046] The terminal device in the embodiment of the application supports receiving a service data package, encapsulating and forwarding a transparent uplink instruction package according to the service data package, analyzing a transparent downlink instruction package to obtain a service processing result, and returning the service processing result to a product server. Moreover, the embodiment of the application further adds a switching server, which analyzes a transparent uplink instruction package to obtain a service data package, transmits the service data package to a master control device, receives a service processing result from the master control device, and encapsulates and forwards a transparent downlink instruction package to the master control device according to the service processing result. This avoids being able to only issue a service data package from the master control device, reduces the network connection requirement between the service instruction sender and the master control device, and improves the flexibility and adaptability of product service execution.

[0047] Referring to Figure 3 , a product service execution flowchart based on the vision internet in the embodiment of the application is shown. In Figure 3In the core server, the master control device, the sub-control device and the terminal device are included. The terminal device is connected with the product server in the video live network product (the business layer), and the product server is connected with the product client. The master control device is connected with the switching server.

[0048] Initially, the switching server needs to establish a communication connection with the master control device. That is, before the terminal device receives the service data packet from the product server in the above embodiment, the master control device receives the login request information from the switching server; the master control device performs login authentication on the login request information to obtain a login response result, and returns the login response result to the switching server; wherein the login request information contains the identity information pre-configured by the switching server and registered in the master control device. In actual application, the switching server can connect to the management interface of the master control device through the socket in the tcp protocol, and initiate a login request to the core server according to the pre-configured username and password. The login request complies with the video live network protocol, and mainly contains the following information: operation code (user login), username, password, heartbeat timeout time, etc. The master control device processes the login request and returns the login result, which mainly contains: operation code (user login response), username, user type, result (0 indicates success, and others indicate failure), etc. If the login is successful, the switching server maintains the heartbeat between the core server to make the login connection not offline.

[0049] It should be noted that the switching server needs to pre-configure multiple different types of usernames and passwords registered in the core server, such as root user, network management user, meeting management user, and transparent user, etc. The various information pre-configured by the switching server can be stored in the local configuration file, and the format of the configuration file mainly includes: core server ip, port, user list (user type, username, password), etc.

[0050] Moreover, before the terminal device receives the service data packet from the product server, the terminal device receives the communication connection information from the product server, and establishes the communication connection between the terminal device and the product server according to the communication connection information. Wherein, the communication connection information contains the network information of the terminal device. In actual application, the product server starts, and establishes the communication connection with the terminal device according to the pre-configured communication connection information (ip, port, etc.). The communication connection information contains the ip and port of the terminal device to be connected.

[0051] After the communication connection between the relay server and the core server is established, and the communication connection between the product server and the terminal device is established, the product client sends a service request (a service data packet) to the product server. The service data packet reaches the terminal device through the communication connection established between the product server and the terminal device, the terminal device acquires the service data packet, encapsulates a transparent uplink instruction packet, and transmits the transparent uplink instruction packet to the corresponding sub-control device, and finally the sub-control device forwards the transparent uplink instruction packet to the master control device. The transparent uplink instruction packet is a command for the Internet-based live streaming product to send a service request to the relay server. The transparent uplink instruction packet mainly includes: an operation code (transparent uplink), an initiating device number, a receiving user identifier, and payload content (the acquired service data packet). The receiving user identifier is an identifier corresponding to the login of the transparent user of the relay server to the core server, which can be stored in a configuration file of the terminal device.

[0052] After the master control device receives the transparent uplink instruction packet, the master control device parses the receiving user identifier and the service data packet. If it is detected that the user corresponding to the receiving user identifier does not establish a connection with the master control device, the service data packet is discarded. If it is detected that the user corresponding to the receiving user identifier establishes a connection with the master control device, the service data packet is forwarded to the relay server.

[0053] The relay server can parse the transparent uplink instruction packet to acquire the initiating device identifier and the service data packet. In addition, the relay server can also acquire the service type according to the Internet-based live streaming protocol by parsing the header of the transparent uplink instruction packet, and store the service data packet in a data packet queue corresponding to the user connection, so as to transmit the service data packet from the data packet queue to the master control device. The service type can include network management service, meeting management service, and the like. In actual application, the relay server can search whether there is a user connection corresponding to the service type according to the service type. If there is a user connection, the service data packet is stored in a data packet queue corresponding to the user connection. If there is no user connection, the relay server searches the account information corresponding to the service type from a configuration file of the relay server, creates a user connection according to the account information, and stores the service data packet in a data packet queue corresponding to the user connection. The above-mentioned user connection can be understood as a user connection established with the core server.

[0054] The service data packet is stored in the data packet queue and waits to be sent to the core server. When the service data packet is sent to the core server, the relay server records the transaction identifier (Internet-based live streaming unique, the transaction identifier in the service data packet and the corresponding service processing result is the same) and the terminal device identifier of the terminal device sending the service data packet.

[0055] If the account information corresponding to the type of service is not configured in the switching server, or the user login fails, the encapsulation service initiation result transparent downlink instruction package is transmitted downward to the terminal device, and the encapsulation service initiation result transparent downlink instruction package mainly includes: operation code (transparent downlink), receiving device number, initiating user identification, and load content (the load content is different for different services, and here is the service initiation result: 0 indicates success, and others indicate failure).

[0056] After the master control device receives the service data package of the switching server, the service data package is parsed and corresponding service processing is performed, and the service processing result is returned to the switching server.

[0057] After the switching server receives the service processing result returned by the core server, the transaction identification in the service processing result is parsed, and the receiving user identification of the service data package is found according to the transaction identification. The switching server encapsulates the transparent downlink instruction package according to the receiving user identification of the service data package and the service processing result, and the transparent downlink instruction package is transmitted to the slave control device by the master control device, and finally transmitted to the terminal device by the slave control device. The transparent downlink instruction package mainly includes: operation code (transparent downlink), receiving device identification, generated user identification of the service processing result, and load content (the load content is different for different services, and here the load content is the service processing result returned by the core server).

[0058] The terminal device receives the transparent downlink instruction package, obtains the load content therein and sends it to the product server, the product server performs corresponding service according to the service processing result, and feeds back the service result to the product client.

[0059] The switching server in the embodiment of the application can parse the transparent uplink instruction package to obtain the service data package, and can also encapsulate the service processing result into the transparent downlink instruction package, and can also encapsulate the service initiation result into the service initiation result transparent downlink instruction package. The switching server establishes a communication connection with the core server through a pre-configured username and password, and keeps the communication connection open. In the case that the video networking product cannot directly connect to the master control device, the switching server can forward the service request of the video networking product to the core server, and return the service processing result of the core server to the video networking product, thereby reducing the network environment requirement of the video networking product.

[0060] The terminal device in the embodiment of the application establishes a communication connection with the video networking product, receives the service request of the video networking product, and forwards the service request to the switching server in the form of a transparent uplink instruction package. Moreover, the terminal device receives the transparent downlink instruction package returned by the switching server, and further parses the service processing result or the service initiation result, and finally returns the service processing result or the service initiation result to the video networking product, thereby avoiding the network condition limitation that the video networking product must be connected to the master control device to initiate a service request, and improving the flexibility of the video networking product to initiate a service request.
