Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 shows a schematic flow chart of a distributed underlying framework building method provided by an embodiment of the present invention, including:
s11, determining a port of each module for network communication with other modules based on the network manager.
In embodiments of the present invention, the configuration file is written by a technician. After the technician writes the completed configuration file, the network manager reads the IP and port defined by the configuration file. And then uniformly allocating a port for each module to perform network communication with other modules according to the network manager. The network manager allocates ports for the modules according to the registration messages sent by the modules to the network manager.
It should be noted that the module is an application program process which can be executed separately. In an embodiment of the present invention, the network manager is shown in fig. 2.
And S12, the sorter in each module sorts the message received by the module, and transfers the message sorting result to each transceiver, and transfers the message transferred by each transceiver to the interface of the module where the sorter is located.
In an embodiment of the invention, the sorter is a core part of the entire module. After each module receives the messages sent by other modules, in order to make each message get its place, the sorter in the module sorts the messages according to the screening condition and transmits the sorted messages to each transceiver. I.e. only one sorter is needed for one module. And the sorter can receive the messages transmitted by each transceiver and transmit the messages transmitted by each transceiver to the interface of the module where the sorter is located.
It should be noted that the module in which the network proxy is located needs to communicate with a plurality of modules, and therefore, a plurality of devices having functions similar to those of a "transceiver", which are called interfaces, are provided for the network proxy. It is responsible for passing information in the network inside the module. In an embodiment of the present invention, the sorter is as shown in fig. 2. The messages delivered by the sorter mainly contain information as shown in figure 3.
And S13, the transceiver in each module receives the message classification result transmitted by the sorter in the module, performs logic processing on the message classification result, and transmits the message classification result after the logic processing to the sorter.
In the embodiment of the invention, each module can simultaneously establish connection with other modules to receive and send messages. For ease of management, each connection is provided with a transceiver for receiving, logically processing and communicating messages to and from it. I.e. one module may have multiple transceivers. After receiving the messages transmitted by the interface, the sorter classifies the messages and transmits the classified messages to each transceiver of the module where the sorter is located. After receiving the classified information, each transceiver in the module can carry out logic processing on the classified information and transmit the classified information after logic processing to the sorter. In an embodiment of the present invention, a transceiver is shown in fig. 2. The message communicated by the transceiver primarily contains information as shown in fig. 4.
S14, when the module of the network agent is used as the server, it monitors the message sent by other modules and transfers the message to the sorter corresponding to the module for sorting, and at the same time, when the module of the network agent is used as the client, it sends the message to other modules.
In the embodiment of the invention, the network agent is a link for connecting other modules and is a channel for communicating the inside of the module with the outside of the module. Each module performs message interaction with other modules through a network, and therefore, each module is respectively provided with a network agent to initiate registration to a network manager for applying for a port of the module. In addition, the module provided with the network agent can be used as a server and a client simultaneously, and an interface is created between the module and other modules to convert network information flow and internal messages. Specifically, when the module where the network agent is located serves as a server, the network agent monitors messages sent by other modules and transmits the messages to the sorters corresponding to the module for classification, and meanwhile, when the module where the network agent is located serves as a client, the network agent sends the messages to other modules. In an embodiment of the invention, the network proxy is shown in fig. 2. The module where the network agent is located forcibly converts the received network data stream into a message class, and then delivers the message class to a sorter for sorting the message. When the module where the network agent is located sends a message to another module, if the other module is not connected with the network, the message is stored in a message buffer area, and after the other module is connected with the network, the message is sent to the other module from the message buffer area; and if the other module is connected with the network, directly sending the message to the other module. The message mainly contains information as shown in fig. 5.
It should be noted that the four steps S11, S12, S13 and S14 are not in sequence. In the process of building the distributed bottom layer framework, any one of the four steps of S11, S12, S13 and S14 can be preferentially carried out, namely the sequence of S11, S12, S13 and S14 can be randomly arranged, and the building of the distributed bottom layer framework is completed.
The embodiment of the invention enables each module to be independently executed at different PC ends by registering the network manager through configuring the IP and the port of the network manager; the flow of each module is similar, and development and implementation are facilitated.
Further, on the basis of the above method embodiment, the network manager includes: and configuring the IP and the network manager of the port according to the configuration file.
In an embodiment of the present invention, the configuration file is written by a technician. And configuring the IP and the port of the network manager according to the configuration file written by the technical personnel.
Further, on the basis of the above method embodiment, the determining, based on the network manager, the port of each module includes:
the network manager records the ID and IP of each module initiating registration to the network manager, and allocates a port for each module;
the network manager sends the ID, IP and port of all modules to each module.
In embodiments of the invention, each module may initiate registration with the network manager. And after receiving the registration message, the network manager records the ID and the IP of each module and allocates a port for each module.
The embodiment of the invention uniformly distributes the interfaces for each module through the network manager, and sends the ID, the IP and the port of each module to other modules, thereby simplifying the configuration process.
Further, on the basis of the above method embodiment, the method for building a distributed underlying framework further includes: a messaging mechanism is set up.
In the embodiment of the invention, in the execution process of each module, not only the output result of each module has an influence on other modules, but also the process variable of each module can trigger the logic operation of other modules, so that the modules are interacted by adopting a message triggering mode. And encapsulating the result generated by the module at any time or under any condition according to the form of the message, and then sending the encapsulated message through the network. As shown in fig. 6.
Specifically, the process of setting up the message mechanism is as follows (as shown in fig. 6):
1) defining a message base class comprising: source address, destination address, type, blacklist and other attributes;
2) in the execution process of the module 1, if the condition of trigger 1 or trigger 2 is met, newly establishing an application message 1 (inheritance message base class) or an application message 2 (inheritance message base class), assigning values to various member variables of the new application message, and then sending the assigned values to the module 2 by a tcp (transmission control protocol);
3) after receiving the application message 1 or the application message 2, the module 2 can analyze the application message according to the type, take the application message as the input for carrying out the corresponding logical operation, and send a message feedback information packet to the module 1 if feedback is needed.
It should be noted here that, because the distributed underlying framework of the present invention is based on object-oriented, in the message transmission process, the message base class is used as a medium to transmit information, and when the transmitted message is used, the transmitted message needs to be converted into information corresponding to the inheritance class.
The embodiment of the invention takes the message base class as the parameter of the method, thereby greatly simplifying the message transmission.
