Detailed Description
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 only a part of the embodiments of the present invention, and not all of the embodiments. 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.
Before explaining the load balancing method of the intelligent park, an application scenario of the intelligent park is explained so that the public can better understand the intelligent park.
In a microservice environment, a microservice framework is usually used to implement operations such as service definition, service discovery, remote service invocation load balancing, fault tolerance processing, and the like, and a dubbo microservice framework is one of the commonly used microservice frameworks. In the dubbo micro-service framework, three roles of a registry, zookeeper, a service provider and a service consumer are mainly included, and after the service provider registers the provided service in the registry, the service consumer can subscribe and call the service in the registry.
The registry can be set according to regions, and the registries of the regions form a registry cluster. In the dubbo micro-service framework, a region is used for representing the region of the registration center cluster, the value of the region is the ID of the corresponding region, a dc is used for representing the intelligent park of the registration center cluster, the value of the dc is the ID of the corresponding intelligent park, and each region comprises a plurality of intelligent parks dc. Similarly, geographically, each service consumer and service provider belongs to an intelligent campus dc in a regional area. The service provider can register the service on any registration center associated with the service provider, and the service consumer can subscribe and invoke the service on any registration center associated with the service consumer.
Based on this, as shown in fig. 1, the method for load balancing of an intelligent park provided by the present application includes the following steps S101 to S103:
step S101, acquiring original registration information of service providers of a plurality of registration centers, wherein the original registration information comprises a park to which the service provider belongs and a region to which the park belongs.
The execution subject of the load balancing method of the intelligent park can be any service consumer. The service consumer is associated with a plurality of registration centers, including the registration center corresponding to the intelligent park where the service consumer is located, the registration centers corresponding to other intelligent parks in the same region with the intelligent park and the registration centers corresponding to other regions. In step S101, the service consumer obtains and integrates the original registration information of the service providers in all the associated registration centers, and the integrated registration information of the service providers still includes the information of the campus to which the service provider belongs and the region to which the campus belongs in the original registration information.
Specifically, when a service provider registers the provided service in a registry, a dubbo registration protocol configuration needs to be filled; when a service consumer subscribes to a service, the service provider is queried from the configuration file of the registry. Therefore, the original registration information of the service provider is dubbo registration protocol configuration information, such as:
<dubbo:registry id="reg1"address="xxx.xxx.xxx.xxx:yyyy"protocol="zookeeper"enable="true"/>
<dubbo:registry id="reg2"address="xxx.xxx.xxx.xxx:yyyy"protocol="zookeeper"enable="true"/>
<dubbo:registry id="reg3"address="xxx.xxx.xxx.xxx:yyyy"protocol="zookeeper"enable="true"/>
the service consumer acquires the configuration files of the associated registration center, and integrates the dubbo: registry protocol configuration information of each configuration file by using the multiplex protocol of the dubbo micro-service framework to obtain the registration information under the multiplex protocol. Instead of specifying the Smart park dc and regional regions, the multiple protocol configuration specifies the Smart park dc and regional regions in the child region configuration under the multiple protocol.
For example:
Figure BDA0003186072090000051
and step S102, determining the proportion of the number of the service providers contained in each park to the total number of the service providers according to the parks to which the service providers belong.
Specifically, a dc value of registration information under a multiple protocol is acquired; counting the number of registration information with the dc value consistent with the ID of the intelligent park where the service consumer is located, namely the number of service providers contained in the intelligent park; the ratio of the number of service providers included in the intelligent park to the total number of registration information under the multiple protocol (i.e., the total number of service providers included in all the registries) is calculated.
And step S103, determining an optional park according to the proportion, and randomly selecting a service provider from the service provider list of the optional park for service calling.
Specifically, a suitable intelligent campus is determined as an optional campus according to the ratio obtained in step S102, where the optional campus is an intelligent campus including an optional service provider. In order to avoid problems such as transaction timeout, the present embodiment preferably uses a high-rate intelligent campus as the optional campus. For example, a proportion threshold value is set, intelligent parks containing service providers with the proportion of the number of the service providers to the total number of the service providers higher than the proportion threshold value are screened, then one of the screened intelligent parks is selected as an optional park, and a service provider is randomly selected from the optional parks to call for services.
In the above embodiment, the service consumer determines a suitable intelligent park according to a ratio of the number of service providers included in the intelligent park to the total number of service providers of all the registries associated with the service consumer, and selects a service provider in the determined intelligent park. Compared with the mode of determining the intelligent park according to the priority setting parameters in the prior art, the configuration operation of the micro-service framework is simplified, the load strategies of all service consumers on the framework level are unified, and the situations of cross-intelligent park and cross-regional service calling caused by the priority setting parameters are avoided.
In an embodiment, as shown in fig. 2, step S103, determining an optional campus according to the ratio, and randomly selecting a service provider from the service provider list of the optional campus to invoke a service, includes:
step S1031, obtaining the proportion of the number of service providers contained in the current intelligent park to the total number of the service providers;
step S1032, when the proportion corresponding to the current intelligent park exceeds a preset threshold value, determining the current intelligent park as an optional park;
and step S1033, when the proportion corresponding to the current park does not exceed the preset threshold, selecting another intelligent park except the current intelligent park from the area where the current intelligent park is located as an optional park.
Step S1034, randomly selecting a service provider from the service provider list of the optional campus to call the service.
In an embodiment, as shown in fig. 3, when the ratio corresponding to the current campus does not exceed the preset threshold, step S1033 may be replaced by step S1035 to step S1037:
step S1035, acquiring a ratio of the number of service providers included in other parks except the current park in the area to which the current park belongs to the total number of service providers;
step S1036, when the proportion corresponding to at least one park in the other parks exceeds the preset threshold value, determining any one of the at least one park as a selectable park;
step S1037, when the proportion corresponding to at least one park does not exist in the other parks and exceeds the preset threshold, namely the proportions corresponding to all parks in the area to which the current park belongs do not exceed the preset threshold, selecting any intelligent park from the area to which the current intelligent park belongs and determining the intelligent park as the selectable park.
In an embodiment, as shown in fig. 4, when the proportions of all the parks in the area to which the current park belongs do not exceed the preset threshold, step S1037 may be replaced with step S1038 to step S1030:
step S1038, judging whether the area to which the current park belongs contains a provider or not;
step S1039, if yes, randomly selecting an intelligent park containing a service provider from the area to which the current park belongs as an optional park;
and step S1030, if not, randomly selecting an intelligent park containing a service provider from other parks except the area to which the current park belongs as an optional park.
