Detailed Description

The embodiment of the application provides a service calling method and device, two service registration methods and devices, and a health checking method and device, which solve the problem of service calling in a multi-stack network environment.

In order that those skilled in the art can better understand the technical solutions of the present application, the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. The application can be practiced in many other ways than those described below, and therefore, based on the examples provided herein, one of ordinary skill in the art will be able to arrive at all other examples that are within the scope of the application without undue burden.

It should be noted that the terms "first," "second," "third," and the like in the claims, description, and drawings of the present application are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. The data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and their variants are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The embodiments of the present application take IPv4 and IPv6 network protocol versions as examples to describe the technical solutions proposed in the present application, but the application field Jing Xian is not limited to IPv4 and IPv6 network protocols, and any scenario where the present application can be used is the scope of the present application, and the present application is not limited by the present description, and therefore the scope of the present application should be defined by the scope of the claims of the present application.

IPv4, a fourth version of the internet protocol (Internet Protocol, IP), uses 32-bit (4-byte) addresses. The network address resource of the current IPv4 address is insufficient, and the application and development of the Internet are severely restricted. For better development, the Internet Engineering Task Force (IETF) was designed to replace the next generation internet protocol IPv6 (Internet Protocol Version 6) of IPv 4. IPv6 uses 128-bit addresses, the number of which is up to 2 ¹²⁸ And the problem of insufficient network address resources is solved.

The upgrade procedure from IPv4 to IPv6 requires a smooth transition procedure to be provided so as to minimize the impact on existing users, and thus may be in a network environment where IPv4 and IPv6 coexist for a considerable period of time. Existing related support services in a single stack network environment cannot be used in a dual stack network environment. The embodiment of the application provides a method for supporting service related to a multi-stack network environment, which can meet the requirement that a dual-stack network simultaneously supports the deployment configuration of IPv4/IPv6 and adds IPv6 service without canceling the IPv4 service.

When the dual-stack network protocol is used, the back-end servers are upgraded from the original IPv4 single stack to the IPv4/IPv6 dual stack, and the service address provided by each back-end server is changed from the original IPv4 single service address to two service addresses coexisting with the existing IPv4 service address and IPv6 service address. The original service discovery capability only supports service registration of a service address of a single IPv4 network protocol version, the original health check strategy in a single-stack environment cannot support the health check requirement in a double-stack environment, and the service call in the single-stack environment cannot meet the uniform forwarding of the service request in the double-stack environment. That is, the existing service calling method in the IPv4 single stack network environment can not solve the problem of service calling in the IPv4/IPv6 dual stack network environment.

Therefore, service invocation in a multi-stack network environment is a highly desirable problem.

The following description will be given of terms related to the technical scheme of the present application.

The service registration may be that the service provider registers the service information on the service registration center.

The health check may be that the service registry checks the available state of the target address information of the target service provider, and adjusts the service address weight information of the target service provider in real time according to the checking result.

The brief procedures of service call, service registration and health check in the single stack network environment in the prior art are as follows:

service calling process: the service calling party obtains the service request message sent by the service request party, determines a target service provider aiming at the service request message according to the service weight information of the service request party, sends the service calling message to the target service provider, and completes the service calling aiming at the service request message.

Registration procedure of service provider: the service provider starts service registration work when a new service node is needed, wherein the new service node is a target service provider, a service address of the target service provider is registered to a service registration center, and the registered service addresses are an IP (Internet Protocol, internet protocol version) address and a Port (Port number); service weight information of a service address of a target service provider is obtained according to the computing capability of the target service provider.

Deletion procedure of service provider: the service registry may directly remove the service provider that needs to be deleted and send the service request message to service providers other than the deleted service provider.

Health check process for service provider: the service registry may discover whether address information of a certain service provider among the service providers is in an abnormal state by detecting. When a certain service provider is found to be abnormal, the abnormal service provider is directly removed, and then a service request message is sent to service providers except the abnormal service provider.

The method is only suitable for a single-stack network environment, the address information of a single network protocol version exists in a multi-stack network environment, and the address information of a plurality of network protocol versions exists at the same time, so that when the address information is the plurality of network protocol versions, the service calling problem in the multi-stack network environment cannot be solved by the method.

An example of a service invocation method provided by the present application is described below. As shown in fig. 1, the present application provides an exemplary diagram of a service invocation method. In order to browse the goods when the user uses the shopping website, if the user wants to access the detail page of the goods or the homepage of the shopping venue or any other service request, the service request message may be an IPv4 service request or an IPv6 service request according to the version of the client or the type of the installed client device, and in this service invocation, the client 101 sends the IPv6 service request 102 message to the service caller, which may be the gateway 103. The gateway 103 includes service weight information, service address information, and service address weight information of the service provider provided by the service registry, and also integrates the load balancing system 104. The gateway 103 determines, through the load balancing system 104, a target service provider, i.e. the service provider 2,105, capable of providing services for the current service request according to the service weight information of each service provider. Further, through health check, the service provider 2 has both IPv4 address information 1051 and IPv6 address information, and both IPv4 address information 1051 and IPv6 address information can provide services for the current service request, and the load balancing system 104 selects the IPv4 address information 1051 to provide services for the current service request according to the service address weight information, and then sends an IPv4 service request 106 including the IPv4 address information 1051 to the service provider 2,105. Eventually, the IPv4 address information 1051 of the target service provider provides services for the client 101, the gateway 103 responds to the IPv4 service response 107 of the service provider 2,105, and the client 101 responds to the IPv4 service response 108 of the gateway 103 to provide services for the service requester. I.e. the user receives on the client 101 a corresponding response content regarding a detail page for accessing the goods or a shopping mall homepage or any other service request. Thus, the service request message can be an IPv4 request or an IPv6 request, and the service call message can be an IPv4 call or an IPv6 call, and the service request message of the client of any network protocol version can complete the service call of the corresponding service provider through the service caller.

The application provides a service calling method, a device, electronic equipment and a storage medium, two service registration methods, a device, the electronic equipment and the storage medium, and a health checking method, a device, the electronic equipment and the storage medium. The technical scheme provided by the application is described below.

The first embodiment of the present application provides a service calling method, and in the following, the service calling method provided by the present application is described in detail with reference to fig. 2. Fig. 2 is a flow chart of a service calling method according to an embodiment of the present application. It should be noted that the steps illustrated in the flowchart may be performed in a computer system, such as a set of computer-executable instructions, and in some cases, the steps illustrated may be performed in a different logical order than illustrated in the flowchart.

As shown in fig. 2, an execution main body of a service calling method provided by an embodiment of the present application is a service calling party, and the service calling method provided by the embodiment of the present application includes the following steps:

step S201, a service request message sent by a service requester is obtained.

This step is used to obtain the service request message sent by the service requester.

The service request message may be a request access message from a client to a server, that is, the service request message may be at least one service request such as a user browsing a web page, a network order, etc.

The service request message includes service request messages of multiple network protocol versions, namely, for one service request, for the existing network protocol, the service request message may be a service request message of an IPv4 network protocol version, a service request message of an IPv6 network protocol version, or a network protocol of a higher level version used in a subsequent continuous upgrading process.

The service request message of the service requester may be at least one service request message of multiple network protocol versions, and for a service request, the service request message is one service request message of one network protocol version, and the current service request may be an IPv4 request or an IPv6 request.

Step S202, determining a target service provider that can provide a service for the service request message.

The step is used for determining a target service provider capable of providing service for the service request message, and determining the target service provider capable of providing service for the service request for one time.

A target service provider for the service request message is determined based on the service weight information for the plurality of service providers.

The service weight information is self attribute characteristics of the service provider and is determined according to the computing capability information of the service provider. Each service provider has own service weight information, and when a service request is made, a plurality of service providers can provide services, and a target service provider for the service request message is determined according to the service weight information of the service providers. In the embodiment of the application, the service provider with the largest service weight information among the plurality of service providers can be used as the target service provider.

For example, the service providers that can provide services for one service request message are the service node 1, the service node 2, and the service node 4, and the service weight information of these three service nodes is 0.4, 0.5, and 0.3 in order, and the service node 2 can be selected as the target service provider.

It is understood that if a service provider having the largest service weight information among the plurality of service providers is temporarily unable to provide a service for various reasons, the service provider having the second largest service weight information may be selected as the target service provider. In this way, the service provider of the third largest, fourth largest, or next largest of the service weight information may be selected as the target service provider.

In the embodiment of the application, the target service provider which can provide the service for the service request message can be determined, or the target service provider can be determined according to the polling and service weight information together, namely the target service provider can be determined according to a weighted polling method.

In step S203, if the target service provider has a plurality of network protocol versions of target address information, and all of the plurality of network protocol versions of target address information can provide services for the service request message, the target address information of at least one network protocol version is selected from the plurality of network protocol versions of target address information to provide services for the service requester.

This step is used for selecting the destination address information of at least one network protocol version from the destination address information of a plurality of network protocol versions to provide service for the service requester if the destination service provider determined in step S202 has the destination address information of the plurality of network protocol versions and the destination address information of the plurality of network protocol versions can all provide service for the service request message.

In the embodiment of the application, the information of the target service provider provided by the service registry is also obtained, and the information of the target service provider comprises the target address information of a plurality of network protocol versions of the target service provider. The information of the target service provider further includes service address weight information corresponding to the target address information of the plurality of network protocol versions, respectively.

Destination address information for multiple network protocol versions of a destination service provider in a service caller is provided through a service registry.

Of course, obtaining the target address information of multiple network protocol versions and the weight information corresponding to the target address information of multiple network protocol versions through the service registry is only one embodiment, and in practical application, the information may also be obtained in multiple manners. For example, the service caller may directly perform a session with the service provider, and the service provider may actively send the information to the service caller, or the service caller may send a request message to the service provider, and obtain the information from the service provider. In addition, the service caller may obtain the information by other third parties who know the information. If a target service provider has target address information of a plurality of network protocol versions, and the target address information of the plurality of network protocol versions can all provide service for a service request message, selecting the target address information of at least one network protocol version from the target address information of the plurality of network protocol versions to provide service for the service requester, comprising:

Obtaining service address weight information corresponding to the target address information of the network protocol versions respectively;

and selecting target address information of at least one network protocol version according to the service address weight information to provide service for the service requester.

The service address weight information is obtained according to the service weight information of a target service provider and the proportion information of at least one network protocol version, which is expected to bear the service response quantity in the service provider.

Continuing with the example in step S202, the service node 2 is selected as the target service provider, the service weight information of the service node 2 is 0.5, if the target address information of the service node 2 is IPv4 service address information and IPv6 service address information, if the ratio information of the IPv4 service address information and the IPv6 address information to the response amount assumed in the service provider is 1:4, the weight information of the IPv4 service address information is 0.5×1/(1+4) =0.5×1/5=0.1, and the weight information of the IPv6 service address information is 0.5×4/(1+4) =0.5×4/5=0.4.

And after obtaining service address weight information respectively corresponding to the target address information of the network protocol versions, selecting the target address information of at least one network protocol version according to the service address weight information to provide service for the service requester.

In the method provided by the embodiment of the application, the target address information of the network protocol version with the largest service address weight information can be selected as the target address information to provide service for the service requester. Of course, in some cases, it is also possible to select the destination address information of the second largest network protocol version of the service address weight information as the destination address information, and it is understood that in some cases, it is also possible to select the destination address information of the third largest network protocol version.

The target address information of at least one network protocol version is selected from the target address information of a plurality of network protocol versions to provide service for a service requester, the target address information can be selected in a polling mode, the target address information can be selected according to an original address hash method, and the target address information can be selected according to a URL (Uniform Resource Locator ) hash method.

The source address hash method is to obtain a numerical value according to the IP address of the client through hash function calculation, and to carry out modular operation on the size of the server list by the numerical value, and the obtained result is the serial number of the server to be accessed by the client.

If the target service provider provides the target address information with only one network protocol version, the target address information of the network protocol version is directly selected as the target address information to provide service for the service requester.

In one example, if the target service provider has only IPv4 target address information, the IPv4 target address information is directly selected as the target address information to provide the service to the service requester. At this time, since one target service provider has only one IPv4 target address information, there is no ratio of a plurality of network protocol versions of target address information to the service response amount in the service provider, in which case there is no service address weight information.

And if the target service provider has target address information of a plurality of network protocol versions, and only one of the target address information of the plurality of network protocol versions can provide service for the service request, selecting the target address information which can provide service for the service request to provide service for the service requester.

In one example, if the target service provider has both IPv4 target address information and IPv6 target address information, but finds that the IPv6 target address information therein is not available in the health check, service cannot be provided, and only the IPv4 target address information can provide service for the service request, the IPv4 target address information is selected as the target address information, and service is provided for the service requester.

The step is used for selecting the target address information of the proper network protocol version from the target service provider, providing service for the service requester and providing basis for subsequent service call.

Step S204, a service invocation message is sent to the target service provider, where the service invocation message includes the invoked target address information of the at least one network protocol version.

This step is for sending a service invocation message to the target service provider, the service invocation message comprising destination address information of the at least one network protocol version invoked. And sending a service calling message comprising the target address information of the called at least one network protocol version to the service provider to complete the service calling process.

In the technical solution provided in the embodiment of the present application, the service request message is used for requesting a target service provider to provide a service for the service requester by using target address information of a specified network protocol version, and the service call message is used for indicating the target service provider to provide a service for the service requester by using target address information of other network protocol versions except the specified network protocol version.

When a service request initiates a service call to a target service provider, the network protocol version of the target address information is irrelevant to the network protocol version of the service requester, and is only relevant to the target address information and the service address weight information of the service provider.

In this example of the present application, the service request message may be an IPv4 request or an IPv6 request; the service invocation message may be an IPv4 request or an IPv6 request. The IPv4 service request message can be called by IPv4 or IPv6 in service call; the IPv6 service request message may be an IPv4 call or an IPv6 call when the service call is made. The network protocol version of the service request message and the network protocol version of the service call message may or may not be identical, and the network protocol version used by the service request message does not affect the network protocol version used by the service call message.

The steps S201 to S204 provide a service invocation method, obtain a service request message sent by a service requester, determine a target service provider that can provide a service for the service request message, and if the target service provider has target address information of a plurality of network protocol versions and the target address information of the plurality of network protocol versions can provide a service for the service request message, select the target address information of at least one network protocol version from the target address information of the plurality of network protocol versions to provide a service for the service requester, send a service invocation message to the target service provider, where the service invocation message includes the target address information of the at least one invoked network protocol version. In this way, after obtaining the service request message sent by the service requester, determining a target service provider capable of providing service for the service request from a plurality of service providers, selecting at least one from the target address information of a plurality of network protocol versions of the target service provider to provide service for the service requester, and finally sending a service call message containing the target address information of the network protocol version to the target service provider to complete service call in a multi-stack network environment. In the above embodiment, a service calling method is provided, and correspondingly, the application also provides a service calling device.

In order to more clearly understand the present application, the technical solutions provided by the embodiments of the present application are described below with reference to fig. 10 and 11. FIG. 10 is a block diagram of an embodiment of the present application; FIG. 11 is a schematic diagram of a load balancing process in a service call. Where the IPv4 network protocol version and the IPv6 network protocol version are currently commonly used network protocol versions, the subsequent use of higher level network protocol versions is not precluded.

The service requester 1001 is a client, and specifically may be an application client, a browser client, an instant messaging client, or the like. The client is installed on an intelligent terminal with a network connection function, and the intelligent terminal can be a smart phone, a tablet computer, a notebook computer, a touch screen, a personal computer (Personal Computer, PC), a personal digital assistant (Personal Digital Assistant, PDA) and the like. The user sends a service request message to a service caller by using a client of the intelligent terminal, the service caller may be a gateway 1003, and the sent service request message may be a service request message 10021 of an IPv4 network protocol version or a service request message 10022 of an IPv6 network protocol version. The gateway 1003 converts the service request message sent by the service requester 1001 into a back-end call of the service caller, and the service request message of the IPv4 network protocol version can be converted into target address information of the IPv4 network protocol version or into target address information of the IPv6 network protocol version; the service request message of the IPv6 network protocol version can be converted into the target address information of the IPv4 network protocol version, and also can be converted into the target address information of the IPv6 network protocol version. The service invoker, i.e., the gateway 1003, has the load balancing system 1004 integrated therein, and the gateway 1003 also includes service address information, service weight information, and service address weight information 1007 of the service provider 1006 obtained from the service registry 1005. The gateway 1003 determines a target address of a target service provider that provides a service for the service request, based on the service address information, the service weight information, the service address weight information 1007, and the load balancing system 1004 of the service provider 1006. The gateway 1003 further sends a service request to the target service provider, which may be a service request message 10021 of the IPv4 network protocol version or a service request message 10022 of the IPv6 network protocol version. The gateway 1003 responds to the IPv4 request or IPv6 request of the target service provider, i.e., IPv4 response 10081 or IPv6 response 10082, and the service requester 1001 responds to the IPv4 request or IPv6 request of the gateway 1003, i.e., IPv4 response 10081 or IPv6 response 10082, to provide the service to the service requester 1001.

As shown in fig. 11, a flow chart of the load balancing process is shown. Step 1101, the load balancing system obtains information of the service provider from the service registry; step S1102, selecting a target service provider capable of providing a service from the service providers according to the service weight information of each service provider; step S1103, determining whether the target service provider has target address information of multiple network protocol versions; step S1104, if yes, discovering that the target address information of multiple network protocol versions can provide service for the service request message through health check; step S1105, selecting a network protocol version of target address information to provide service for a service requester according to the service address weight information corresponding to the target address information; in step S1106, a service call message is sent to the target service provider, where the service call message includes the target address information of the called network protocol version.

Step S1107, after step S1103, of determining that the target service provider does not have the target address information of multiple network protocol versions, where the target service provider has only the target address information of one network protocol version; in step S1106, a service call message is sent to the target service provider, where the service call message includes the target address information of the network protocol version.

Step S1108, after step S1104, the health check finds that only the target address information of one network protocol version can provide service for the service request message; in step S1106, a service call message is sent to the target service provider, where the service call message includes target address information of the service to be provided.

In addition to completing the service call to the service request message through the load balancing system as described above, a service registration 1010 is required for the newly added service provider of the service provider. When a newly added service provider is online, registration of relevant information such as service address information, service weight information, service address weight information 1007, and the like of the service provider 1006 is completed in the service registry 1005. The gateway 1003 obtains the related information of the service provider registered in the service registration center 1003, and performs health check and weight update on the service address information of the service provider 1006. Specifically, the response characteristic of the service address to the detection information can be judged whether to conform to the preset response characteristic by sending the detection information to the service address of the service address information, if so, the service address is determined to be available, otherwise, the service address is determined to be unavailable. If judging that the service addresses of the target service provider are not available, directly moving out of the target service provider; and if the target service provider is judged to have available part of service addresses and the other part of service addresses are not available, adjusting the service address weight information of the service addresses, namely updating the weight of the service address weight information. By the method, service call under the multi-stack network environment is completed.
