All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Referring to fig. 1, fig. 1 is a flowchart of a data communication method according to an embodiment of the present application.
The specific steps may include:
s101: starting a router service in target FC node equipment, and creating a monitoring service by using the router service;
the method and the system can be applied to target FC node equipment in an FC network, wherein the FC network also comprises other node equipment, and application programs are run on the target FC node equipment and the other node equipment. The FC network is a new high-speed network which is parallel to the traditional TCP/IP network, and has own address allocation and network system. Referring to fig. 2, fig. 2 is a schematic diagram of a communication architecture based on an FC network provided in the embodiments of the present application, in fig. 2 dev_ A, DEV _ B, DEV _c is an FC node device in the FC network, and each node device is running a plurality of application programs APP, a routing service router, an operating system OS, and a driver FC driver, and each FC node device is connected to an FC switch through an FC port, where P1, P2, and P3 … … P13 represent the FC port. As shown in fig. 2, this embodiment proposes an architecture based on the FC (FC-AE-ASM protocol) network and communication between different APPs, to solve the problem that different APP developers want to exchange data with each other. By the scheme of the invention, the development period of an application developer can be obviously shortened. The configuration function in the architecture mainly completes the setting of key parameters of a protocol, such as the version of software, authors, node addresses in an FC network, port ids, published topic ids, subscribed topic ids, execution strategies corresponding to topics and the like. The service provided by the software corresponding to the architecture mainly comprises the following two aspects: (1) The router root service is provided, and the main function is to monitor the states (up/down, and error codes) of all hardware nodes of the FC network, monitor the states (up/down, subscribe/publish, and forward data) of the APP in the current device. (2) The client lib is provided, and the main function is to provide a set of standard API interfaces, and a user can communicate with other applications by using the API interfaces.
Before the step, a router service can be set in the self-starting script of each FC node device as the self-starting service, and after the router service in each FC node device is started, a corresponding monitoring service is created according to the configuration information of the config file.
S102: monitoring other FC node devices in the FC network through the monitoring service, and establishing an FC network topology structure according to a monitoring result;
in this embodiment, data monitoring and/or status monitoring may be performed on other FC node devices in the FC network by using a monitoring service, so as to complete discovery work of each node in the FC network, and implement establishment of an FC network topology structure.
Further, after the router service is started, the FC node device may start an application APP of the user, where the application APP registers an ID with the router and applies to create a session port session, and the router service in each device node broadcasts the ID of the application APP and session port session information to other device nodes in the FC network, thereby implementing sharing of APP information. Specifically, after the router service in the target FC node device is started, a target application program of the target FC node device may be started, a program ID and a session port of the target application program may be registered in the router service, and the program ID and the session port of the target application program may be broadcast to the other FC node devices. The above operation may also be performed by other FC node devices in the FC network, and the program ID and the session port of the application running on the FC node device may be broadcasted, so that the FC node devices in the FC network all have the program ID and the session port of the application of the FC node device.
S103: if an operation request of a target application program is received, processing the operation request;
the target application program runs on the target FC node device, and the operation request of the target application program may include any one or a combination of any of a Login operation (logic) request, a log-out operation (logo) request, a topic publication (Pub) request, a cancel topic publication (hensub) request, a topic subscription (Sub) request, a cancel topic subscription (un) request, a topic data publication (Send) request, and a topic data reception (Recv) request. The target FC node device may process the operation request of the target application according to information shared by all FC node devices in the FC network. The topic data publishing operation Send can only Send and publish topic data, and if no topic is published, the data cannot be sent. The topic data receiving operation Recv can only receive subscribed topic data, and topic data without subscription cannot be received.
S104: and generating communication data according to the processing result of the operation request, and broadcasting the communication data to other FC node devices by utilizing the router service according to the FC network topology structure.
After the operation request is processed, a corresponding processing result can be obtained, and camping communication data is generated based on the processing result. For example, after the login operation is allowed, the corresponding relationship between the login user name and the target application program can be used as communication data. According to the method and the device, the communication data can be broadcast to the other FC node devices according to the FC network topology structure, so that all the FC node devices in the FC network can store the processing results, and the application programs running on different FC power saving devices can share information. Specifically, the embodiment may broadcast the communication data to the other FC node devices according to the FC network topology by using the router service in a string form.
The embodiment starts a router service in the target FC node device, and creates a monitoring service by using the router service, wherein the target FC node device can monitor other FC node devices in the FC network by using the monitoring service to obtain an FC network topology structure.
