The application interface layer mainly comprises a client program, an application programming interface, a WEB browser, a third-party software tool and a management console. The management console is a user management interface that provides management and configuration functions for the administrator for application services.

The service framework layer comprises a monitor and a gateway system (comprising a private gateway and a REST gateway) which are responsible for processing external concurrent call connection and analyzing request data, and functional modules such as a BBS bulletin board, system management, an application server, transaction processing and running real-time library which are responsible for application interaction.

The data access layer is composed of application service programs written by users and is responsible for processing various business data.

The base support layer is responsible for supporting heterogeneous hardware, networks, operating systems, and database servers.

The application interface layer, the service framework layer, the data access layer and the basic support layer form an enterprise transaction middleware platform, so that developers can establish a cross-platform interoperable application system, and the unified and centralized data service resource processing platform and the independent and scattered application clients work cooperatively to jointly realize resource integrated management under an industrial Internet platform.

The gateway of the transaction middleware is a software system for realizing application layer protocol conversion, and is also an inlet and an outlet for information interaction with an external system. The private gateway adopts an enterprise private protocol to carry out data communication, and a client program invokes a specific application programming interface to finish the functions of connecting a gateway system, requesting service, processing business data, logging off connection and the like, so that the safety and privacy of the data are protected.

The REST gateway is a network software system based on REST architecture style and adopting international open standard HTTP (hypertext transfer protocol)/1.1 protocol. It uses a uniform interface specification to define the way the resource operates, uses a uniform resource identifier URI (Uniform Resource Identifier) to identify the resource location, uses media types (e.g., JSON, XML, etc.) for data interactions.

Through HTTP protocol, REST gateway can realize loose coupling based on data interaction between WEB browser, client program and server application service processing program, provides convenient, flexible and safe interface calling mode based on browser/server architecture in service frame layer, and possesses basic functions of load balancing, flow control, SSL encryption, authentication, etc.

The REST gateway is composed of a monitor and a gateway processor, as shown in fig. 2.

Each set of transaction middleware REST gateway system comprises a monitor and a plurality of gateway processors which are flexibly configured, so that the throughput of the system and the processing capacity of a server side can be effectively improved. The client program completes network transmission of the request data through HTTP protocol, the gateway processor efficiently transmits the application data contained in the request message to the application server for processing through inter-process communication, and after obtaining the response data, the response message is replied, and the main service functions are as follows:

1. and the client calls the REST resource address and establishes socket connection with the monitor.

2. The listener passes the socket connection handle to the gateway processor, after which the communication connection of the client is handled by the latter, and the listener is no longer involved.

3. The gateway processor is responsible for transmitting data at the TCP layer, decrypting and analyzing the HTTP request message through an upper SSL protocol, and obtaining application data.

4. The gateway processor delivers the data to the application server, which returns response data after execution by the service program.

5. The gateway processor obtains the response data, encapsulates the response data into an HTTP response message, and replies to the client after encrypting the HTTP response message through SSL protocol.

Wherein the listener module comprises:

The listener module is a network entry of the transaction middleware software system, and the client is connected with the REST gateway system through the listener. The listener is responsible for listening to the HTTP/S protocol port and the UNIX domain socket (Unix Domain Socket) port, receiving the connections of the external client and the internal gateway processor, respectively.

It selects a gateway processor according to a random scheduling policy of load balancing or a lightest load policy and transmits a client connection handle to the gateway processor, and the gateway processor performs data interaction with a client by the gateway processor, and the functional flow is shown in the following figure 3.

The "load balancing random scheduling policy" and the "lightest load policy" are the existing techniques that the trading middleware has implemented.

The gateway processor module includes:

the gateway processor responsible for resolving and packaging HTTP request and response messages is a core module of the REST gateway system and is also a basic component for realizing rapid calling of application services and processing of high-concurrency connection.

The bottom layer structure is based on an event driven software design mode, adopts a single thread asynchronous processing and concurrent connection Reactor (Reactor) programming model, uses an I/O multiplexing separator (select/poll function) of an operating system as a basic component of an event driven cycle, continuously checks signal events, timing events and I/O handle input/output read-write events, processes other ready network events by waiting for the timing events to be triggered, performs data dispatch, executes a callback function registered for the events in advance, notifies a service object of receiving data, and then completes protocol analysis of HTTP request messages.

The method combines an efficient inter-process communication mechanism in the transaction middleware, and reads response data processed by the application from the memory in a non-blocking manner while processing various network events in a serial and asynchronous manner, so that the efficient communication function of the system is realized.

The gateway processor module workflow is shown in fig. 4.

As shown in FIG. 5, the gateway processor module is composed of four functional sub-modules, namely a connection management sub-module, an information security processing sub-module, an HTTP protocol processing sub-module and an application data interaction sub-module.

The connection management sub-module is responsible for communication between the gateway processor and the monitor, establishes and manages connection with external client requests, establishes association between the socket connection handle and the SSL layer, sets data read-write events, and ensures stable and efficient data transmission. The functions are as follows:

1. Responsible for connecting, disconnecting, or reconnecting listeners.

2. And receiving the client socket connection handle forwarded by the listener.

3. An association is established between the connection handle and the SSL layer.

4. And interacting with the SSL layer, and establishing a secure connection through the information security processing sub-module exchange key and authentication.

5. And setting a callback function of the data read-write event for the socket connection handle.

6. The running state of the gateway processor is informed to the monitor in real time.

The information security processing sub-module comprises:

the secure sockets layer (Secure Sockets Layer, abbreviated SSL) protocol is an industrial internet privacy standard for encrypting and securing communications. The method is positioned between a TCP transmission layer and an application layer, and establishes a secure communication channel for both a client and a server.

The information security processing sub-module is responsible for encrypting and decrypting the actual transmission message for both communication parties. The key links of the information security accurate processing and the high-efficiency realization are checking certificates, identity verification, selection algorithms, negotiation protocol versions and keys.

First, the SSL protocol establishes a secure channel based on a handshake protocol and a recording protocol by the following steps, as shown in fig. 6.

And then, the information security processing sub-module encrypts and decrypts the data message by using the generated symmetric key, wherein the rules are as follows:

1. And the plaintext data which is decrypted by the SSL layer and arrives is informed to the HTTP protocol processing submodule for analysis by an event-driven callback mechanism.

2. The transmitted plaintext data is encrypted by the symmetric key of the SSL layer and then transmitted to the outside by the TCP transmission layer.

The mechanism realizes the data encryption function in the transmission process and provides safer and more reliable network communication service.

The HTTP protocol processing sub-module comprises:

The submodule is used for analyzing and packaging HTTP/1.1 request and response messages.

Firstly, it is responsible for analyzing the received plaintext data according to the HTTP/1.1 protocol requirement, removing the beginning line, the head field and the blank line ending symbol of the HTTP request message, collecting the subsequent data body according to the length field value of the head, and then delivering to the application server for processing, wherein the analyzing workflow is shown in figure 7:

The application service interaction submodule comprises:

the REST gateway adopts an FML32 (FIELD MANAGEMENT Language) format as a data structure for interaction between the gateway and the application server, and the dynamic construction problem of the application data structure is flexibly realized.

The application service interaction sub-module reads the processed response data from the memory through an inter-process communication mechanism, encapsulates the response data into an HTTP response message, encrypts the HTTP response message through the information security sub-module and replies to the client.
