Detailed Description
Embodiments and examples of the present invention will be described in detail below with reference to the accompanying drawings.
The scope of applicability of the present invention will become apparent from the detailed description given hereinafter. It should be understood, however, that the detailed description and the specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only.
Fig. 1 shows a flow chart of a preferred embodiment of a data transmission method according to the present invention.
The method of the present invention is applied to a system including an intranet service, a gateway service, and an extranet service, and data transmission is performed between the intranet service and the extranet service through the gateway service, as shown in fig. 2. According to the invention, an independent service registration center is defined in each independent gateway service, and the functions of the service registration center comprise interface detection service and service health check of the associated system such as an intranet system and an extranet system, and whether the interface and/or the service is available or not can be detected at regular time.
In step S102, the health status of the intranet service and/or extranet service registered to the service registration center is periodically checked, for example, the intranet service and/or extranet service can be checked for being on-line, off-line, modified, etc. by calling a health check interface provided by the intranet service/extranet service center.
In step S104, it is determined whether the data transfer service is abnormal. If so, the process proceeds to step S106; otherwise, the process returns to step S102. In an embodiment, whether a data transfer service is abnormal may be determined by the number of times it failed. If the service response time is too long and a plurality of failures occur, for example, the number of failures exceeds a predetermined number, for example, due to occupation of server resources, the data transmission service is defined to be abnormal.
In step S106, a fusing mechanism is initiated, i.e. the corresponding data transmission is suspended and the service provider is notified of the service anomaly. And after receiving the service abnormal notification, the service provider checks the service health state, restarts the service after the check is finished and registers the service in the service registration center.
In step S108, after the abnormal data transmission service is restarted successfully, all service subscribers are notified to recover the corresponding data transmission service.
Despite the complexity of system interaction, through service subscription, after the service is restarted, the service information is published to the related system in time, and after the related system obtains the information, the data transmission service is automatically restarted. Therefore, under the complex scenes of deployment environment and network environment, the multiple systems are fused in time in the face of the scene that part of services are unavailable, unnecessary network and resource consumption is reduced, and after the services are recovered, a data synchronization mechanism is started in time, so that reliable data transmission is ensured in the service available state.
In an embodiment, the service registry also implements the following functions: and detecting whether the data transmission interface of the internal network and/or the external network is available at regular time. For example, the detection may be performed by active detection, and if the synchronization data is successful, the interface is available, and if the synchronization data is failed, the interface is not available. And the detection can also be realized in a passive notification mode, if the service provider actively notifies the service subscriber abnormally, the data transmission is immediately recovered to the service subscriber synchronously after recovery. In response to a data transmission interface being unavailable, suspending corresponding data transmission and initiating network detection service; and stopping the network detection service and recovering the corresponding data transmission service in response to the detection that the network is recovered to be normal. By aiming at the particularity of different scenes, different fusing recovery mechanisms are adopted, so that the service fusing recovery mechanism based on the combination of service subscription, broadcast notification and network monitoring is provided, the processing measures are more targeted, the effect of reducing the resource and network consumption is better, and the recovery of data transmission is more timely.
In an embodiment, whether the corresponding data transmission interface is available may be determined by a network outage time. For example, it may be determined whether the network outage time exceeds a predetermined threshold, and suspending data transmission for data transmission services that exceed the predetermined threshold may reduce unnecessary resource consumption. In other words, the fusing mechanism is not activated when the network is interrupted for a short time, and is activated when the network is interrupted for a long time.
In an embodiment, the network detection service may determine whether the network is back up through heartbeat monitoring. The service of the service registration center can send a heartbeat request to the service centers of other systems at regular time, if the heartbeat request is not received within a certain period of time, the system network can be determined to be interrupted, otherwise, the network is normal.
In an embodiment, for a scenario where an intranet has multiple system interactions, in addition to a gateway service, a partial service in the intranet may use the above mechanism to ensure transmission of data exchanged between a hospital and the gateway, that is, an additional service registry is deployed in one or more intranet services, and data exchange transmission between the intranet service and the gateway through the additional service registry is similar to the data exchange transmission between the service registry deployed in the intranet through the gateway and an extranet described above, so that the problems of data loss and inconsistency caused by unavailability of the partial service are avoided, and while the request pressure of a server is reduced, final consistency of data between multiple systems is ensured. Of course, for the same server, network heartbeat monitoring may be omitted.
Fig. 3 shows a block diagram of a preferred embodiment of a data transmission system according to the present invention. The data transmission system comprises an intranet service, a gateway service and an extranet service, wherein data transmission is carried out between the intranet service and the extranet service through the gateway service, each independent gateway service defines an independent service registration center, and each service registration center comprises:
