Detailed Description
The following description of the embodiments of the present invention will be made apparent and fully in view of the accompanying drawings, in which some, but not all embodiments of the invention are shown. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Fig. 1 to 3 show a cross-network service switching system of the present invention, which includes at least two independent service networks, and when data is exchanged between the two independent service networks, as shown in fig. 1, the cross-network service switching system includes the following modules:
Cross-network data exchange equipment: the control module is used for connecting two independent service networks to perform data ferry between the networks;

The system is also used for receiving and analyzing the response data packet transmitted by the cross-network data exchange equipment and transmitting the analyzed response data packet to the application client;
Service agent module: the request data packet is used for receiving and analyzing the request data packet transmitted to the service agent module of the service side by the cross-network data agent switching equipment, and the analyzed request data packet is sent to the target service appointed by the request data packet;

In this embodiment, the request packet is request data encapsulated using a communication protocol of the service side, and the response packet is response data encapsulated using a communication protocol of the request side. Because the two independent service networks use the data packet encapsulated by the communication protocol at the other side to communicate at the other side, the data packet is converted into the format allowed by the cross-network data exchange equipment through the proxy module, the data packet is transmitted through the cross-network data exchange equipment between the two independent service networks, then the data packet is analyzed through the proxy module at the other side, and is transmitted to the appointed target service to obtain the response data, and then the response data is converted into the format allowed by the cross-network data exchange equipment again, and is transmitted to the request proxy module to be analyzed through the transfer relay of the cross-network data exchange equipment, and then the response data is transmitted to the corresponding client. By the method, the proxy modules respectively deployed in the two independent networks and the cross-network data exchange equipment are used, so that the two independent service networks can communicate.
In this embodiment, a request agent module or a service agent module in each service network registers on the cross-network data exchange device, and establishes a logical link relationship according to the need. The cross-network data exchange equipment follows a plug mechanism and expands according to the need. Only two independent service networks, namely the connection of the application side and the service side, are required to be established according to the requirement to exchange data.
The request side is a network of one side sending out the request, and the service side is a network of one side providing the service, so that the service proxy module can be set on the side as long as the service can be provided, and the request proxy module can be set on the side as long as the request can be sent out, but the request proxy module or the service proxy module on the other side needs to be registered on the cross-network data exchange equipment, and the cross-network data exchange can be carried out after the logical link relation is established according to the requirement. The data is not required to be moved to the request side and updated according to the update frequency, so that the consistency of the data is ensured, meanwhile, the data is not required to be copied to the request side requiring the data, so that the system security is improved, the data is not required to be moved to the home position by copying the data, the consistency of the data is ensured, further, the client side directly accesses the service program of the service side, the network is not copied to the application side by the data, the security level of the network at the application side is not improved, and the service instantaneity is better and the security is greatly improved.
In this embodiment, the request agent module includes a forward agent sub-module, configured to receive a request packet of a request side sent by an application client, and further configured to send a response packet to a corresponding request client. Responding to the request data packet by means of a forward proxy sub-module, wherein the forward proxy sub-module is different from the traditional forward proxy sub-module, the request data packet is sent to a specified target service, the received data packet is packaged into a format file required by cross-network data exchange equipment, the format file is transmitted to the cross-network data exchange equipment and is transferred to a service proxy module of a service side, and the service proxy module comprises a reverse proxy sub-module which is used for sending the request data packet analyzed by the service proxy module to the specified target service; and is also configured to receive a response packet from the target service to the request packet. The reverse proxy sub-module in the service proxy module fulfills the responsibility of the reverse proxy sub-module, the analyzed request data packet is sent to the appointed target service program to obtain the response data of the target service program, the response data packet is packaged into a format response file required by the cross-network data exchange equipment, and the response data packet is sent to the corresponding request client by the forward proxy sub-module in the request proxy module through the cross-network data exchange equipment and transferred to the request proxy module of the request side.
In this embodiment, the request agent module further includes a request aggregation sub-module, configured to aggregate a plurality of request data packets into a plurality of request data packets, where the request agent module sends the plurality of request data packets to the cross-network data switching device for transmission, and the service agent module parses the received plurality of request data packets to obtain parsed plurality of request data packets, and sends the parsed plurality of request data packets to a target service specified by each request data packet through the reverse proxy sub-module.
Similarly, the service agent module further includes a service convergence submodule, configured to converge a plurality of response data packets into a multi-response data packet, where the service agent module sends the multi-response data packet to the cross-network data switching device for transmission, and the request agent module parses the received multi-response data packet and sends the parsed response data packet to each request client through the forward agent submodule. Because the application request service requests pages for more than ten interfaces and even tens of interfaces, the large number of simultaneous online users makes the use rate of the cross-network data exchange equipment ultra-high. And the data generated by a single request rarely exceeds a few megabytes, but the data length is too small for the cross-network data exchange equipment, and is a waste of data exchange IO resources. Therefore, in this embodiment, the request aggregation sub-module is set, and after aggregating a plurality of request data packets, the request aggregation sub-module is packaged into a multi-request data packet, and the multi-request data packet is transmitted through the cross-network data exchange device, so that on one hand, data exchange resources are saved, and on the other hand, when a large number of users are involved, the request aggregation sub-module can timely aggregate the requests for transmission, and has better instantaneity. Similarly, a service convergence sub-module is set, and after a plurality of response data packets are converged, the response data packets are converted into a format required by the cross-network data exchange equipment for transmission.
In this embodiment, the request packet, the multi-request packet, the response packet, and the multi-response packet are converted according to the transmission format requirement of the cross-network data switching device, and then the transmission ferry of the packets is performed. For example, if the format of the cross-network data exchange device data ferry is required to be a file format, the request agent module sequences the received request data packet into a request file, and only the request data packet is encapsulated according to the file format required by the cross-network data exchange device ferry for transmission. As shown in fig. 3, in order to sequence the request packet into the request file, a serialization method is used as a data packet encoding method. Of course, other methods of serialization may be used. Since the method of serialization is a common method. The data message coding method is a message provided with a message header, a data area and a message tail, wherein the message header comprises proxy module information and data message coding identification information, covers all information required by request identification and response association, and is consistent in content for each request, so that the message header is uniformly placed. The data area comprises a plurality of subareas, each subarea corresponds to a request data packet or a response data packet, and the message tail contains verification information for data of the data area. Through verification, after consistency of the request file or the response result file transmitted by the cross-network data exchange equipment in the file transmission process is ensured, the request file or the response result file is analyzed. And (3) checking by adopting a whole section of report Wen Yici, checking by adopting CRC16, and setting the initial value to be 0 by adopting a polynomial of x16+x12+x5+1. The method can meet the basic data verification requirement, has small calculation amount and is suitable for Ethernet network data verification.
The invention creatively uses the request with the appointed communication protocol in the request data packet, the request appoints the address of the target service, so that the cross-network service proxy module obtains the address of the target service program appointed by the request after receiving the analysis of the request data packet transmitted by the network gate, calls the target service, obtains the response and returns the response result. Therefore, the method is a response to the request, the data does not fall to the ground, data moving is not needed, and the consistency of the data is ensured. And the data in the database does not need to be moved to the application side, thus avoiding losing secret and improving the network security level of the application side.
In this embodiment, as shown in fig. 2, the principle that the request convergence submodule receives a plurality of request data packets is to perform format conversion on a plurality of request data packets or response data packets and then perform data ferrying according to a transmission requirement of the cross-network data exchange device when the length of the plurality of request data packets reaches the transmission requirement length of the cross-network data exchange device or when the time of receiving the plurality of request data packets reaches a preset time;
The principle of the service convergence sub-module receiving the plurality of response data packets is that when the lengths of the plurality of response data packets reach the transmission requirement length of the cross-network data exchange equipment or when the time of receiving the plurality of response data packets reaches the preset time, format conversion is carried out on the plurality of response data packets and then data ferrying is carried out.
