The inventors have appreciated that: based on data security considerations, a gatekeeper is typically used between two different networks to block direct TCP (Transmission Control Protocol ))/IP (Internet Protocol Address, internetworking protocol) connections from communicating directly based on the communication transmission protocol. Therefore, the data transmission between different networks is complicated and the communication efficiency is low every time the network gate is crossed.
To solve the above-mentioned problems, various embodiments are provided below, and each of the embodiments provided below can be used to achieve efficient data transmission between different networks, so as to achieve efficient call of clients located in the different networks to a server.
Fig. 1 schematically shows an environmental application schematic of a data processing method according to an embodiment of the invention.
As shown, it comprises a first network 1 and a second network 2, said second network 2 being different from said first network 1. Wherein the client 3 and the first front end processor 4 are located in the first network 1, and the second front end processor 6 and the server 7 are located in the second network 2. The client 3 may be connected to the first front-end processor 4 through the first network 1, and the first front-end processor 4 may be connected to the gatekeeper 5 through the first network 1; the gatekeeper 5 may be connected to the second front-end processor 6 through the second network 2, and the second front-end processor 6 may be connected to the server 7 through the second network 2. It should be noted that, the geographic location where the first network 1 is deployed is different from the geographic location where the second network 2 is deployed, or the security of the first network 1 is different from the security of the second network 2.
The first network 1 and the second network 2 may each comprise various network devices, such as routers, switches, multiplexers, hubs, modems, bridges, repeaters, firewalls, proxy devices, and/or the like. By way of example, the first network 1 and the second network 2 may comprise physical links, such as coaxial cable links, twisted pair cable links, fiber optic links, combinations thereof, and/or the like. The first network 1 and the second network 2 may also comprise wireless links, such as cellular links, satellite links, wi-Fi links and/or the like.
The client 3 may initiate a call request to the server 7 to obtain corresponding response data from the server 7. The client 3 may be a service system in a low density network. The service system in the low-density network may be understood as a service system in a network with a low server density and a low security level. The client 3 may comprise any type of device, such as: mobile devices, tablet devices, laptop computers, smart devices (e.g., smartwatches, smart glasses), virtual reality headphones, gaming devices, set-top boxes, digital streaming devices, robots, vehicle terminals, smart televisions, electronic book readers, MP4 (moving picture experts group audio layer IV) players, and the like.
The first front end processor 4 is used for converting between the message and the file. The first front end processor 4 may be any type of server.
And the gatekeeper 5 is used for forwarding files and checking files among different networks. The gatekeeper 5 may be an information security device that connects two independent networks using a solid state switching read-write medium with multiple control functions. Because the two independent networks are isolated through the network gate, no physical connection, logical connection and information transmission protocol exist between the networks, no information exchange according to the protocol exists, and no protocol ferry is performed only in the form of data files. Therefore, the network gate logically isolates and blocks all network connections with potential attacks on the internal network, so that external attackers cannot directly invade, attack or destroy the internal network, and the safety of each network is ensured.
And the second front end processor 6 is used for converting the messages and the files. The second head-end 6 may be any type of server.
And the server 7 is used for generating and returning corresponding response data according to the call request. The server 7 may comprise any type of server, such as: rack servers, blade servers, tower servers, or rack servers (including stand-alone servers, or a server cluster made up of multiple servers), and the like. In this embodiment, the service end 7 may be a service system in a high-density network. The service system in the high-density network may be understood as a service system in a network with a higher server density and a higher security level.
The application provides a data processing scheme crossing networks, and aims to realize the mutual conversion between a message and a file based on a communication transmission protocol through a first front-end processor and a second front-end processor, thereby realizing efficient data transmission between different networks.

Example 1
In an embodiment, the cross-network data processing method can be applied to the military or public security industry.
Referring to fig. 2, a flowchart illustrating overall steps of a data processing method across networks according to a first embodiment of the present invention is shown. As shown in fig. 2, the data processing method across the network may include steps S200 to S204, wherein,
Step S200, a first communication transmission protocol request message sent by a client is received through a first front-end processor, the first communication transmission protocol request message is converted into a request file, and the request file is forwarded; the first front-end processor and the client are located in a first network.
The communication transmission protocol related to this embodiment includes, but is not limited to, HTTP protocol (Hyper Text Transfer Protocol ), HTTPs protocol (Hyper Text Transfer Protocol over SecureSocket Layer, hypertext transfer security protocol), qic protocol (low latency internet transport layer protocol based on UDP; UDP is User Datagram Protocol, user datagram protocol), SSL protocol (Secure Sockets Layer, secure socket protocol), and the like. In this embodiment, the first communication transmission protocol request packet may be an HTTP protocol request packet. In other embodiments, the first communication transmission protocol request message may also be an HTTPS protocol request message, a QUIC protocol request message, or an SSL protocol request message.
The file format of the request file includes, but is not limited to, JSON (JavaScript Object Notation, JS object profile) or XML (Extensible Markup Language ), etc.
In order to realize high-performance service, the first front-end processor bottom layer adopts Netty as a network communication framework, wherein the Netty framework is the framework of a high-level network using Java (computer programming language) for rapidly developing high-performance and high-reliability network servers and client programs. The first front end processor may process multiple requests simultaneously.
In order to achieve the mutual conversion between the first communication transmission protocol request message and the request file, referring to fig. 3, the converting the first communication transmission protocol request message into the request file may further include steps S300 to S304, where: step S300, a first file is created in a disk of the first front-end processor through the first front-end processor; step S302, analyzing the first communication transmission protocol request message to obtain the content in the first communication transmission protocol request message; and step S304, writing the content in the first communication transmission protocol request message into the first file to obtain the request file. In this embodiment, the first front end processor 4 is configured with a conversion function, and the conversion function of the first front end processor 4 implements the mutual conversion between the first communication transmission protocol request message and the request file, and the request file obtained by conversion is stored in the first front end processor 4. In order to improve the security of data transmission, the method further comprises: the first front end processor 4 checks the request file.
Step S202, receiving the request file forwarded by the first front end processor through a gateway, and forwarding the request file.
In order to improve the security of data transmission between different networks, the method further comprises: and checking the request file through the gatekeeper, and forwarding or intercepting the request file according to a checking result. In this embodiment, the file format of the request file, whether the request file includes an illegal keyword, whether the request file includes a sensitive word, whether the request file includes a virus, whether the request file includes a malicious insert program, and the like are checked by a security policy preset in the gatekeeper 5. If the verification result shows that the verification of the request file is passed, forwarding the request file to the second front-end processor 6; if the verification result shows that the verification of the request file fails, the request file is intercepted, and response information showing that the connection fails is returned to the client 3. And the data verification is carried out on the request file from multiple dimensions through the network gate, so that the safety of data transmission among different networks is effectively improved.
Step S204, receiving a request file forwarded by the gatekeeper through a second front-end processor, converting the request file into a second communication transmission protocol request message, and forwarding the second communication transmission protocol request message to a server, so that the server generates and returns a target response message based on the second communication transmission protocol request message; the second front-end processor and the server are located in a second network, and the second network is different from the first network.
Wherein, netty is adopted as a network communication framework at the bottom layer of the second front-end processor 6.
In order to enable efficient communication between different networks, as shown in fig. 4, the second front-end processor 6 is configured with a thread pool, where the thread pool includes an IO thread (In and Out thread, an input/output thread) and a service thread; the IO thread is configured to send the second communication transmission protocol request packet to the server 7. The method may further comprise: step S400, if the second communication transmission protocol request message is sent to the server through the IO thread, calling the service thread to wait for the server to return the target response message and blocking the service thread; and step S402, if the target response message is received within the preset time, waking up the service thread, converting the target response message into a target response file through the service thread, and forwarding the target response file to the gatekeeper through the IO thread. In this embodiment, the thread pool further includes other service threads, where the other service threads are used for time-consuming service processing, such as sensitive word verification, keyword filtering, virus killing, and the like. The IO threads are different from the business threads and other business threads. And through the cooperation of the IO thread and the service thread, the asynchronous communication is converted into synchronous communication, and a synchronous communication mechanism corresponding to the request and the response one by one is realized, so that high-concurrency service call is realized. And the service thread waits for the service end 7 to return the target response message and processes other services through other service threads, so that asynchronous communication of the IO thread is not blocked, and the second front-end processor 7 is facilitated to rapidly process the high-concurrency request file.
In an exemplary embodiment, the method may further include: and if the target response message is not received within the preset time, returning timeout response information representing calling timeout. Illustratively, if the service thread does not receive the target response message within 3 seconds, the service thread provides timeout response information to the client 3, so that the client 3 can do subsequent operations.
In order to guarantee a one-to-one correspondence of requests and responses under highly concurrent requests, referring to fig. 5, the method may further include: step S500, when the target response message is received and the service thread is awakened, a target identifier in the target response message is obtained, and whether the target identifier is the same as a preset identifier in the second communication transmission protocol request message is judged; and step S502, if the target identifier is the same as the preset identifier, determining that the target response message corresponds to the second communication transmission protocol request message, and further determining to provide the target response message to the client. In this embodiment, the first communication transmission protocol request packet carries a unique preset identifier; the request file can take the preset identification as the file name; the second communication transmission protocol request message also carries the preset identifier. According to the comparison of the target identifier and the preset identifier, the one-to-one correspondence between the request and the response can be ensured under the high concurrency environment without network connection.
In an exemplary embodiment, the target response message is a first communication transmission protocol response message. The method may further comprise: receiving a first communication transmission protocol response message provided by the server through a second front-end processor, converting the first communication transmission protocol response message into a response file, and forwarding the response file; receiving a response file forwarded by the second front-end processor through a gateway, and forwarding the response file; and receiving the response file forwarded by the gateway through the first front-end processor, converting the response file into a second communication transmission protocol response message, and forwarding the second communication transmission protocol response message to the client. In this embodiment, the conversion function of the "message-file" configured by the first front-end processor and the second front-end processor is used to implement the mutual conversion between the response message and the response file based on the communication transmission protocol, so as to implement the mutual access intercommunication between the services of different networks.

In step S606, the second front end processor 6 sends the second communication transmission protocol request message to the server 7 through the IO thread.
Step S608 and step S700 are advanced.
The sending is to send the second communication transmission protocol request message to the Socket of the server 7 through the Socket of the second front-end processor based on the connection Channel (Netty Channel) in the open state.
In step S608, the second front end processor 6 invokes the service thread and waits for the target response message within a preset time.
In step S700, the server 7 receives the second communication transmission protocol request message and returns a target response message.
Referring to fig. 7, in the server 7, step S700 may include steps S702 to S708, wherein:
in step S702, the server 7 receives the second communication transmission protocol request message through its connection channel. In step S704, the server 7 calls the service interface (API, application Programming Interface) according to the second communication transmission protocol request message to obtain the target response message.
In step S706, the server 7 writes the target response message into its connection channel.
In step S708, the server 7 sends the target response message to the second front end processor 6 through its connection channel.
Referring to fig. 6, after step S608, the process advances to step S612.
