Description

Load control method

This disclosure relates to a control method, and particularly relates to a load control method.

In network software systems, load control technology is a widely used technology. This technology can split the original functions horizontally according to actual needs, and assign workloads or tasks to different programs, devices or nodes.

Take load balancing technology as an example, which is generally implemented by hardware, for example, a load balancing device is connected to multiple servers, and tasks are dynamically allocated according to the resource usage of the servers. On the other hand, a software method is used to achieve load balancing, such as Nginx. This method has the default polling and least connection method requiring all servers to be stateless. However, load balancing devices are expensive, and for enterprises with relatively low business volume, using load balancing devices is not the first choice. In addition, relying on Nginx to achieve load balancing, enterprise software (such as ERP) must be stateless at the beginning of the design, otherwise it will increase subsequent modification and maintenance costs, and require that the content of each node deployment is completely consistent. Accordingly, how to efficiently and reduce the cost to achieve load control is an urgent problem to be solved.

The content of the invention aims to provide a simplified summary of the disclosure so that readers have a basic understanding of the disclosure. This summary of the present invention is not a complete summary of the present disclosure, and its intention is not to point out important/key elements of the embodiments of the present invention or to define the scope of the present invention.

According to an embodiment of the present disclosure, a load control method is disclosed. The load control method includes the following steps: sending a service request through the client program; reading the business domain directory to parse the resource label; searching in the service container according to the resource label to determine whether there is a corresponding service; and when the corresponding service is not found, Then search for the corresponding service in the business partition container to read the business partition of the corresponding service and connect to the corresponding server of the business partition to distribute the service request of the client program and the server load caused by it.

Please refer to FIG. 1, which illustrates a schematic diagram of the service procedure of accounting data in some embodiments of the present disclosure. A plurality of accounting data can be stored in the target server (not shown) at the same time. The content of one accounting data 100 is illustrated in FIG. 1. As shown in FIG. 1, the accounting data 100 includes a business partition 110 including connection information 111 and a business partition identifier 113. The connection information 111 may record a uniform resource identifier (Uri, Uniform resource identifier) about the service partition and related information about the connection operation. The service partition identifier 113 may be used to identify the service resource classification. For example, if it is a service provider, it will identify 113 Smart Business Event Processing (SBEP) and Report Server. In some embodiments, the target server is configured with an accounting data management tool and/or a text editor, and the administrator can directly modify the corresponding accounting data through the accounting data management tool and/or the text editor. Add a business partition to the accounting data of the target server for load balancing or business level splitting. It should be noted that the term "accounting information" in this disclosure document can be used interchangeably with "account set", which refers to relevant accounting or financial information.

In one embodiment, the service zone identifier 113 includes an identifier and a communication method. The business partition identifier is configured to identify different business resource classifications, such as SBEP, Report Server, etc. The communication method records the communication that the client program (such as service consumer or user) can use Information technology to connect to the server server, for example, Internet address (IP address), port, security logo, service entrance and other information.

For the client program, the manager can define the client program under the business domain directory (such as MONITOR_EVENT) through the design tool or the editing tool. It is worth mentioning that the business domain directory described here can be a directory of folders in a computer operating system, or a hierarchical directory of virtual folders. In one embodiment, the target server provides a client program to connect through an interface (such as a business partition function point), so that the client program uses related services. The service partition function point (or function point for short) includes a unique identifier, a service partition identifier of the server program, and the name of the server program (for example, the name of an application programming interface (API)). It is worth mentioning that one or more function points are included in a function package, and each function point defines at least one function or service program. Therefore, the unique identifier of each function point mentioned above cannot be repeated in the same function package.

In one embodiment, after the target server is started, the business partition 110 of each accounting data 100 as shown in Figure 1 is loaded to read the configuration of each accounting data 100, such as Internet Protocol (IP ) Address, port, security label, service entry and other information. The target server stores the read data in the accounting data model to complete the initialization process of the target server.

In one embodiment, one or more client devices are communicatively connected to the target server. After the client device is started, the login procedure is executed. During the login process, one of the accounting data 100 in the accounting data model is selected on the target server.

Then, the client device parses the accounting data 100 to establish a service request procedure. For example, the client program reads the business partition 110 in the accounting data 100, and creates the resource link information corresponding to the business partition 110, as shown in Table 1 below. The client program reads the corresponding resource connection information according to the business partition to use the service request process indicated by the resource connection information.

Please refer to FIG. 2, which illustrates a schematic diagram of the client program loading the business domain directory 210 and the service container 220 in some embodiments of the present disclosure. As shown in FIG. 2, when the client program reads the business domain directory 210, it reads at least one function package (not shown) of the business domain directory 210, and reads one or more function points 211 of the function package. Function points include unique identification and service zone identification. The interpreter (not shown) of the client program analyzes the content of each function point 211. After analyzing the content of the function point, the relevant information of the function point 211 is written into the service container 220.

The service container 220 includes a resource key 221 (Resource Key) and a business partition 223 (Business Partition). The interpreter reads the function point 211 and parses the content of the function point 211. For example, when The unique identifier of the function point 211 is "IPublishService", and the interpreter writes "IPublishService" into the resource identifier 221. In one embodiment, "IPublishService" represents that the function point 211 is used to provide the function of publishing an update service interface. When the service partition identifier of the function point 211 is "SBEP", the interpreter writes "SBEP" into the execution service partition 223.

In one embodiment, when the resource indicator 221 in the service container records the information about the function points of the service partition, the service container belongs to the service partition service container. In other embodiments, when the resource indicator 221 in the service container does not record the data about the function points of the service partition, the service container belongs to the general service container. Wherein, both the business partition service container and the general service container contain data of at least one function point.

Please refer to FIG. 3, which shows a schematic diagram of establishing a resource access link 300 in some embodiments of the present disclosure. After the service container 220 in Figure 2 is established, a plurality of service containers can be constructed as resource access links. As shown in Figure 3, the client program 390 executes the program that calls the service to obtain service resources. For example, the client program 390 executes a unified execution program GetService("MONITOR_EVENT", typeof(IPublishService)), where the first parameter of the execution program GetService() is the business field, and the second parameter is the service type.

In an embodiment, the service container may or may not have an execution service partition that meets the delivery parameters. As shown in Figure 3, the client program 390 first obtains the transfer parameters of the execution program, and according to the transfer parameters The data is searched and compared in a dictionary in the general service container 310. If the transfer parameter corresponding to the business field is retrieved, the client program 390 allocates the corresponding service request to the designated service container, that is, the business partition service container 320 in FIG. 3. Then, using the business partition and resource link information of the business partition service container 320 (see Table 1 above), the computing resource or service request is indicated to the corresponding resource link. In an embodiment, the business partition service container 320 allocates computing resources to the general service container 330 or the general service container 340. In another embodiment, if the transfer parameter corresponding to the business field is not retrieved in the general service container 310, the general service container search is performed, and the service data is returned according to the search result.

Please refer to FIG. 4, which shows a schematic diagram of establishing a resource access link 400 in other embodiments of the present disclosure. The difference between the resource access link 400 in Figure 4 and the resource access link 300 in Figure 3 is that the resource access link 400 in Figure 4 includes more than one service partition service container (for example, service partition service container 420 and business partition service container 450). Due to the dependency and/or calling sequence among service containers, the service request program of the client program can be distributed in one or more service containers. For example, the publishing service (such as “IPublishService”) is transferred to the general service container 440, and the log service (ILogService) is called after the publishing service is completed, and the service is in the general service container 460.

Please refer to FIG. 5, which shows a schematic flow diagram of a load control method in some embodiments according to the present disclosure. Please refer to Figure 2, Figure 3 and Figure 5 for the following description. In step S510, the client device requests a service, for example, a service request of "IPublishService" is issued begging. In step S520, the client program reads the business domain directory 210 and constructs the service container 220 to parse out the resource identifier. In step S530, the client program searches in the general service container 310 according to the resource identifier to find whether there is a corresponding service.

If the service does not have a business partition identifier, step S540 is executed to find the corresponding service in the general service container 310, and the client program executes the general service container search in a software system (such as an enterprise resource planning system (ERP)), and returns the service resource .

If the service has a service partition identifier, step S550 is executed to find the corresponding server that should be connected to according to the service partition and resource link information in Table 1 above. Then, in step S560, the client service connects to the server corresponding to the service partition and resource connection information, and returns the service resource. For example, when the business partition is SBEP, the client program connects to the SBEP server.

In summary, the load control method disclosed in the present disclosure provides a simple configuration method, and does not need to purchase expensive hardware equipment (such as F5 equipment) to balance the load in the network. In addition, the load control method does not need to modify the existing function codes, and it is easy for developers to learn. As long as the developer understands the technology of the function package and function point, it can be implemented. In addition, the load control method provides a design of arbitrary granularity, supports business level splitting, and thus can provide highly scalable load balancing operations.

The features of several embodiments are summarized above so that those skilled in the art can better understand the aspects of the present invention. Those familiar with this technique should It is understood that the present invention can be easily used as a basis for designing or modifying other processes and structures, so as to implement the same purpose and/or achieve the same advantages of the embodiments described herein. Those familiar with the art should also realize that such equivalent structures do not depart from the spirit and scope of the present invention, and various changes, substitutions and alterations herein can be made without departing from the spirit and scope of the present invention.
