Message-oriented architecture business process control engine

The invention relates to a message-oriented architecture business process control engine, in particular to a field belonging to Business Process Management (BPM), and the invention uses a Message Driven algorithm as a message-oriented control engine. The core technology to cope with the complex and complex Telecom Provisioning Process.

Today's network provisioning architecture is a unique and highly customized product challenge for programmers whenever new services or new network devices and architectures are available. If you rewrite a new program every time the network architecture changes, it will only make the program developers exhausted, and you can't use the original program. List the missing items from the prior art as follows:

1. The prior art uses the database table to control the entire flow control state (State Management). The disadvantage is that the related programs in the process need to monitor the process table status field, and the related process programs can query or even change the column. Bit status, when the status is wrong, the cause of the error is not known by the program, and the responsibility cannot be clarified.

2. The previous program contains business processing logic and process state management. Each program in the process needs to know the state to be processed, and must also know the status code to be processed after processing. This message is directed to the architecture business process control engine (Message Driven Business Process Control Engine) separates process state management. Thus, after the program's business processing logic is complete, there is no need to know the next state, and instead the message-oriented architecture business process control engine controls the actions to be performed in the next step.

3. The message-oriented control engine uses a pre-defined process module to sequentially determine the call business logic module. This process engine changes the previous multi-processing method to multi-threading (Multithreading) mode execution flow control.

4. It is difficult for previous programs to implement parallel processes or asynchronous processes for immediate processing and multi-thread execution. This control engine can easily handle this problem and achieve these goals.

It can be seen that there are still many shortcomings in the above-mentioned methods of use, which is not a good design, but needs to be improved.

In view of the shortcomings of the above-mentioned conventional methods, the inventor of the present invention has improved and innovated, and after years of painstaking research, he finally successfully developed and completed the business process control engine of the message-oriented architecture.

The object of the present invention is to provide an opportunity to speed up the processing time of the process and reduce the cost and process error of the network supply system, and also reuse the original process or expand the process module to shorten it. System development time.

The second object of the present invention is to provide a state control that is independent of the program in the original program, and the program itself is solely responsible for the business logic, and no longer needs to control the actions to be performed in the next step of the flow, the flow control Part of this is directed to the message-oriented control engine to be responsible. In addition, the use of this message-oriented control engine can avoid the disadvantages of multiple program control database status fields, which is more conducive to clarifying the lack of responsibility.

The message-oriented architecture business process control engine that achieves the above-mentioned inventions is mainly composed of a communication module and a process processing module, and uses a mail delivery (Mail Delivery) algorithm to process the message applied to the business process control engine (Business). In the Process Control Engine), the present invention can support the network loading action required for the telecommunication resource binding supply process, and the process processor can then capture the packet of the process message through the message box, and then according to the source of the message. To determine the action to be performed in the next step of loading, and then generate a new thread according to the action to be performed to execute the required processing items (eg: Start, End, Fork, Merge, Pick, Loop, Decision). , CallOrch, StartOrch, Delay, Action), after the processing of the pending project is completed, the message packet is returned to the message box, and the processing is continuously processed to the end. After the execution is completed, the message content is transmitted back to the communication module. The communication module will then transmit the message content to the external system for reception.

Please refer to FIG. 1 , FIG. 3 and FIG. 4 , which are diagrams of the business process control engine of the message-oriented architecture provided by the present invention, which are mainly composed of an external system 1, a message-oriented control engine 2, a communication module 3, and a process.

After receiving the message, the process program of the Orch Template 42 and the template data 43 is determined according to the source of the message, and the action to be processed is determined according to the process program, and then a new one is generated according to the action to be performed. The thread executes the required process operation (Process Operation)9.

The message-oriented control engine 2 is mainly composed of a communication module 3 and a process processing module 4, and its functions are respectively listed as follows:

1. Communication module: The main part is to make the external communication part of the process into a module, which is dedicated to communication, message routing and message processing. The communication module encapsulates the communication operation between the present invention and other external systems into the channel of the communication module 2; the communication module 2 mainly receives and transmits information to the outside, and the communication module Group 2 can also convert the data of the external system 1 into internal messages, and design the internal information to separate the process processing module from the communication module, so as to achieve the advantages of the professional division of each module. The main purpose of this communication module is to encapsulate the complexity of communication between all systems. It unifies the different transmission methods into a simplified interface. Among them, the channel can be divided into two parts: input 阜 (InPort) 6 and output 阜 (OutPort) 7, and there is a special synchronization communication, that is, after the transmission needs to wait for the message to be transmitted back, the communication component itself Name it Input In (OutOutPort) 8.

The Input Port transmission method provided by input 可6 can be divided into:

◆ FTP

◆ HTTP

◆ FILE

◆ SOCKET

◆ Web service

◆ JMS

The Output Port transmission method provided by the output 阜7 can be divided into:

◆ JMS

◆ SMS

With this unified channel interface, the system communication interface designer can quickly assemble a new transmission method, or design the required communication format according to the interface data format, and use the settings to inject the address to be transmitted and received into the communication profile. The channel communication engine (Channel Communication Engine) can start receiving the background service (Daemon) of the communication according to the set setting, and the transmitting part can realize the transmission step by using the obtained transmission object according to the set communication profile, thereby simplifying the communication step. the goal of. For example, when we replace the underlying communication with a new transmission method: EAI, we can use the new transmission method by using the following steps to design a new communication protocol, and the upper layer flow control design. Not completely unchanged.

In addition, the functions of input 阜6 and output 阜7 are listed as follows:

1. Input 阜6: The input 阜6 is designed to receive messages from EAI JMS.

2. Output 阜7: The output 阜7 is designed to transmit EAI JMS messages.

Second, the process processing module 4: the process sequence algorithm executed by the process processing module 4 is as follows:

1. The message-oriented control engine 2 receives the external message data from the message box 5 in the process by using the InPort Channel expansion component in the communication module 3.

2. When the input channel (InPort Channel) expansion element receives the message data of the external message feeding process, it is transmitted to the message box 5 by the message transmitting element of the present invention.

3. Enter 阜6 to convert the input data into the internal message format of Message Box 5.

4. The internal message is converted to the global variable of the message box 5, and the data record is stored in the process processing database 42.

5. After inputting the message from the message box 5, the input box 6 of the message box 5 calls the process handler 41 in the process processing module 4.

6. After the process processor 41 receives the message, it will judge the name and type of the component to be processed according to the source of the message.

7. If the previous message is not found in the message-oriented control engine 2, the template data 43 of the process is searched for in the process processing database 42, and the process is newly established in the process processing database 42.

8. If the message record has been processed in the process, the message-oriented control engine 2 uses the Correlation Id in the message as the primary key, and the source, the destination, that is, the component to be processed. Name and type.

9. Execute the components of the processing item 9 according to the name of the component to be executed, using the Spring Framework's Control Transfer (IoC) dynamic call component method.

10. After the processing item 9 is executed, the message content is transmitted back to the message box 5 using the OutPort Channel expansion element.

The component of item 9 in Figure 5 is an extensible process unit processing component designed as an elastic and reusable component design method. The process processing functions are listed as follows:

1. Start, End: Process start and end processing components, common parts of what to do for the beginning and end of the process will be written here.

2. Fork, Merge, Pick: The process can be divided into multi-path divergence processes in parallel; the merger will need to wait for the multi-party divergence process to end and then proceed; A single sub-division process can be executed at the end.

3. Loop (Loop), Selection (Decision): The loop is a loop process component. If the condition is met, it will be executed in this loop until the condition is not met. The selection is to identify the process component. If the condition is true, The process of executing the condition is established, and the process of not establishing is performed.

4. Call sub-process (CallOrch), start sub-process (StartOrch): Both process components are call sub-processes, where the difference is that the call sub-process needs to be executed after the sub-process execution is finished, if the sub-process is started No need.

5. Delay: This component is a delay flow component that sets the time to delay.

6. Action: This component can be used to expand the code part of the process, so that the process designer can add the code and components written by himself, and the process can call this expansion component through this component.
