Detailed Description
Firstly, it is worth explaining that the industrial internet identification analysis system mainly comprises an identification distribution management system and an identification analysis system, wherein the identification is an 'identity card' of a machine and an article, has uniqueness, and is managed in a hierarchical mode of step-by-step distribution. The identification analysis system utilizes the identification to position and inquire information of the machine and the article, which is the premise and the basis for realizing the accurate butt joint of the global supply chain system and the enterprise production system, the full life cycle management of the product and the intelligent service. By building a set of perfect identification analysis system, powerful support can be provided for industrial system interconnection and industrial data transmission and exchange, interconnection and intercommunication of industrial elements such as design, research, development, production, sales and service of industrial products are really realized, and the cooperation efficiency is improved.
The industrial internet identification analysis system is composed of elements such as an international root node, a national top level node, a secondary node, an enterprise node, a public recursive analysis node and the like, as shown in fig. 1, fig. 1 is a schematic diagram of a logic framework of the industrial internet identification analysis system. The international root node is a service node of the highest level of the identification and analysis system, is not limited to a specific country or region, and provides public root zone data management and root analysis service for the global scope.
The national top-level node is an international gateway interconnected to the outside, is a core hub integrated to the inside, is a top-level identification service node in a country or a region, and can provide top-level identification analysis service, identification filing, identification authentication and other management capabilities for the national range. The national top level node is communicated with international root nodes of various identification analysis systems and is also communicated with various second-level and other identification service nodes below the national top level node.
The secondary node is an identification analysis public service node in an industry or region, and can provide identification code registration and identification analysis services for the industry or region, complete relevant identification service management, identification application docking and the like. The secondary node is not only upwards butted with the national top level node, but also downwards distributes identification codes for industrial enterprises, provides identification registration, identification analysis, identification data service and the like, and simultaneously meets the requirements on safety, stability, expansibility and the like. Each secondary node is assigned a unique secondary node identification prefix by the national top level node.
The enterprise node is an identification analysis service node in an enterprise, and can provide identification code registration and identification analysis service for a specific enterprise. The enterprise nodes can be independently deployed and can also be used as the constituent elements of an enterprise information system. Each enterprise node is allocated with a unique enterprise node identification prefix by a secondary node, the content of the identification suffix is defined and allocated by an enterprise, and the enterprise node identification prefix and the identification suffix form a complete industrial internet identification.
The public recursion analysis node is a key entry facility of the identification analysis system, and the whole service performance can be improved through technical means such as caching. When an identifier analysis request of a client is received, a public recursion analysis node firstly checks whether a local cache has a query result of the identifier, if not, the public recursion analysis node queries through a response path returned by an identifier analysis server until an address or information associated with the identifier is finally queried, returns the address or information to the client and caches the request result.
The query trigger of the identifier resolution service can come from many different forms such as an enterprise information system, an industrial internet platform, an industrial internet APP and the like. In other words, the enterprise information system, the industrial internet platform, the industrial internet APP, and the like can serve as a client to send a query request to the public recursive analytic node, after receiving the query request, the public recursive analytic node first queries the identifier in the analytic server of the top level node of the country and returns address information of the second level node of the identifier to the public recursive analytic node, the public recursive analytic node queries the analytic server of the second level node according to the address information and receives address information of the enterprise node returned by the second level node, the public recursive analytic node queries the identifier in the analytic server of the enterprise node according to the address information of the enterprise node and receives identifier analytic information returned by the enterprise node, and the public recursive analytic node returns the identifier analytic information to the client. Fig. 2 is a process diagram of an identity resolution service, as shown in fig. 2.
In the application, the country top-level node, the second-level node, and the enterprise node are all identification resolution nodes, and can process an identification resolution request sent by a recursive resolution node (i.e., a public recursive resolution node), and return a processing result (i.e., queried address information) to the recursive resolution node.
Each identifier resolution node generally corresponds to a plurality of resolution servers, and the IP address and the port of each resolution server form a resolution interface of the resolution server, that is, one identifier resolution node includes a plurality of resolution interfaces.
The inventor finds in research that, at present, after receiving an identifier resolution request, a recursive resolution node usually randomly calls a resolution interface of a resolution service node to process the identifier resolution request to obtain resolution information of an identifier, and this way cannot guarantee load balance of the resolution interface, which easily causes an excessive load on a single resolution interface.
In view of the above problems, an embodiment of the present application provides an interface calling method and apparatus for an identifier resolution node, where the method is applied to a recursive resolution node in an identifier resolution system, where the recursive resolution node is in communication connection with the identifier resolution node, and first obtains each resolution interface of the identifier resolution node to which a prefix of a target identifier belongs, and determines a current round-trip delay of each resolution interface as a first round-trip delay of the resolution interface; when an identifier analysis request aiming at the target identifier is received, calling a first analysis interface in each analysis interface to process the analysis request according to the magnitude relation of the first round-trip delay of each analysis interface, wherein the first analysis interface is different from a second analysis interface called aiming at the identifier analysis request last time. According to the method and the device, when the analysis interface is called every time, calling can be carried out according to the size relation of the first round-trip delay of each analysis interface, and the first analysis interface called this time and the second analysis interface called last time are not the same, so that the balanced load of each analysis interface is guaranteed, and the overlarge pressure of a single analysis service interface is avoided.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. 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 application.
Referring to fig. 3, fig. 3 is a flowchart of an interface calling method for identifying a resolution node according to an embodiment of the present application. The method is applied to a recursive analysis node in an identification analysis system, the recursive analysis node is in communication connection with the identification analysis node, the identification analysis node comprises a plurality of analysis interfaces, and the method comprises the following steps:
step S11, obtaining each parsing interface of the identifier parsing node to which the prefix of the target identifier belongs, and determining the current round-trip delay of each parsing interface as the first round-trip delay of the parsing interface.
And the target identification is an industrial internet identification cached by the recursive resolution node.
Step S12, when receiving an identifier parsing request for the target identifier, invoking a first parsing interface of each parsing interface to process the parsing request according to a magnitude relationship of a first round-trip delay of each parsing interface.
The first analysis interface is different from a second analysis interface called for the identifier analysis request last time or the first analysis interface is the current analysis interface with the minimum first round-trip delay in each analysis interface.
Optionally, in this embodiment, first round-trip delay of each parsing interface is obtained, and when an identifier parsing request for the target identifier is received, it is further required to determine whether the current target identifier is cached in the recursive parsing node, and if the target identifier is not cached in the recursive parsing node, it is required to call the parsing interface to process the identifier parsing request for the target identifier. In this embodiment, the first analysis interface called this time is determined according to the magnitude relationship of the first round-trip delay of each analysis interface, so as to ensure balanced load of each analysis interface and avoid excessive pressure of a single analysis service interface.
Optionally, in this embodiment, the obtaining each parsing interface of the identifier parsing node to which the prefix of the target identifier belongs, and determining a first round-trip delay of each parsing interface includes:
sending an interface acquisition request to an upper-level identification analysis node to which the prefix of the target identification belongs according to a preset time interval so as to acquire each analysis interface of the identification analysis node to which the prefix of the target identification belongs; sending an identification analysis request to each acquired analysis interface; and determining the difference value between the time of sending the identifier analysis request and the time of receiving a request processing result returned by the analysis interface as the first round-trip delay of the analysis interface.
In this embodiment, the recursion resolution node sends a request to the upper-level identifier resolution node to which the prefix information belongs according to the prefix information of the currently cached identifier at a preset time interval (for example, every 30 minutes), so as to obtain all resolution interfaces of the identifier resolution node corresponding to the prefix information of the identifier.
For example, if the identified prefix information belongs to a second-level node, the recursive analysis node sends a request to a previous node of the second-level node, that is, a top-level node of the country, every 30 minutes to obtain all analysis interfaces of the second-level node, and at this time, the second-level node is the identified analysis node in the embodiment of the present application.
After acquiring the analysis interface of the identification analysis node, the recursion analysis node sends an analysis request to all analysis service interfaces, records the Time (namely Round-Trip Time, RTT) required by each analysis interface for sending and processing the analysis request and returning the processing result to the recursion analysis node, and determines the difference between the Time for sending the identification analysis request and the Time for receiving the request processing result returned by the analysis interface as the first Round-Trip Time delay of the analysis interface.
When an identification analysis request sent by a client is received, the recursive analysis node calls a first analysis interface to process the identification analysis request according to the magnitude relation of the first round-trip delay of each analysis interface, and the called first analysis interface is different from a second analysis interface called for the identification analysis request at the last time.
Optionally, in an implementation manner of this embodiment, step S12 includes:
and polling and calling each analysis interface in turn according to the sequence of the first round-trip delay of each analysis interface from small to large so as to ensure that the first analysis interface called this time is different from the second analysis interface called last time.
In the above step, for example, assuming that the identifier resolution node includes four resolution interfaces in an order of A, B, C, D where round-trip delays are from small to large, the four resolution interfaces are sequentially called according to the order of A, B, C, D when the resolution interfaces are called, if the recursive resolution node calls the resolution interface a this time for processing the identifier resolution request, and when the identifier resolution request is received next time, the recursive resolution node calls the resolution interface B for processing, so that it is ensured that the resolution interface called each time is not the same as the resolution interface called last time, and thus it is ensured that the loads of the resolution interfaces are balanced.
Optionally, in another implementation manner of this embodiment, when the first parsing interface is the parsing interface with the smallest current first round-trip delay among the parsing interfaces, the method further includes:
and updating the first round-trip delay of the first analysis interface after the first analysis interface completes one-time processing of the identifier analysis request.
In the above step, for example, assuming that the identifier resolution node includes four resolution interfaces in the order of A, B, C, D, where the round trip delays of the resolution interface A, B, C, D are 2ms, 5ms, 6ms, and 10ms, respectively, when the first resolution interface is called, the resolution interface with the smallest round trip delay, i.e., resolution interface a, is called from A, B, C, D. And calling the analysis interface A at the recursive analysis node, and updating the round-trip delay of the analysis interface A through a round-trip delay updating algorithm after the identification analysis request is processed, wherein the round-trip delay of the analysis interface A is assumed to be 8ms after being updated. When the identifier resolution request is received next time, the resolution interface with the smallest round trip delay, i.e., resolution interface B, is called again according to the latest round trip delay of the resolution interface A, B, C, D.
Optionally, in an implementation manner, after the first parsing interface completes one processing of the identifier parsing request, updating the first round-trip delay of the first parsing interface includes:
after the first analysis interface completes the processing of the identifier analysis request once, determining that the first analysis interface completes the second round-trip delay of the identifier analysis request this time and the first analysis interface completes the third round-trip delay of the last identifier analysis request;
calculating a fourth round-trip delay of the first analysis interface according to the second round-trip delay and the third round-trip delay of the first analysis interface;
updating the first round trip delay of the first parsing interface to the fourth round trip delay.
In the above step, assuming that the second round-trip delay (i.e. the time required for responding to the identifier analysis request of this time) when the analysis interface a completes the identifier analysis request of this time is 3ms, and the third round-trip delay when the identifier analysis request of the last time is completed is 2ms, the round-trip delay of the analysis interface a may be updated according to the second round-trip delay of 3ms and the third round-trip delay of 2ms, so as to obtain the fourth round-trip delay.
Optionally, the round trip delay may be updated according to a weighted average method, and a weight is set for the second round trip delay and the third round trip delay respectively, and if the weight of the second round trip delay is 0.4, the weight of the third round trip delay is 0.6, then the fourth round trip delay = 0.4+ 0.6=2.4ms, and then the fourth round trip delay 2.4ms is the first round trip delay after the update of the analysis interface a.
Optionally, if the identifier resolution request processing is first identifier resolution request processing after obtaining each resolution interface of an identifier resolution node to which a prefix of a target identifier belongs, updating a first round-trip delay of the first resolution interface after the first resolution interface completes the identifier resolution request processing once, including:
after the first analysis interface finishes the processing of obtaining the identifier analysis request, calculating a fourth round-trip delay of the first analysis interface according to a first round-trip delay of the first analysis interface and a second round-trip delay of the first analysis interface finishing the first identifier analysis request; updating the first round trip delay of the first parsing interface to the fourth round trip delay.
In the above step, the first processing of the identifier resolution request means that the recursive resolution node receives the identifier resolution request sent by the client for the first time after acquiring each resolution node. When the called first analysis interface completes the processing of the first identifier analysis request, the first analysis interface does not have the round-trip delay record of the last identifier analysis request, therefore, when the first round-trip delay of the first analysis interface is updated, the fourth round-trip delay of the first analysis interface is directly calculated based on the first round-trip delay when the first analysis interface is called and the second round-trip delay required by the completion of the identifier analysis request, and the first round-trip delay of the first analysis interface is updated to be the fourth round-trip delay, wherein the first round-trip delay refers to the current round-trip delay of the first analysis interface when the identifier analysis request is received for processing.
For example, if the first round-trip delay of the analysis interface a when being called is 2ms, and the second round-trip delay of the analysis interface a when processing the current identifier analysis request is 3ms, the fourth round-trip delay is calculated according to the first round-trip delay and the second round-trip delay. Optionally, a weight is set for the first round trip delay and the second round trip delay respectively, and assuming that the weight of the first round trip delay is 0.4, and the weight of the second round trip delay is 0.6, the fourth round trip delay = 0.4+ 0.6=2.4ms, and the fourth round trip delay 2.4ms is the updated first round trip delay of the analysis interface a.
Optionally, in another embodiment, after the first parsing interface completes one processing of the identifier parsing request, updating the first round-trip delay of the first parsing interface includes:
and after the first analysis interface completes one-time processing of the identifier analysis request, increasing the first round-trip delay of the first analysis interface according to a preset proportion.
In the above step, assuming that the first round-trip delay of the analysis interface a is 2ms and the preset proportion is 3%, after the recursive analysis node calls the analysis interface a to complete one identifier analysis request, the first round-trip delay of the analysis interface a is increased by 3%, and the increased round-trip delay =2 x (1 + 3%) =2.06 ms. Therefore, the first round trip delay after the update of the analytic interface a is 2.06 ms.
After the first round-trip delay of the called first analysis interface is updated through the two round-trip delay updating algorithms, the analysis interface with the minimum round-trip delay is called according to the updated first round-trip delay, so that the round-trip delay of the called first analysis interface is always the minimum value, the optimal analysis interface can be called when the analysis interface is called next time, and the overall efficiency of identification analysis is improved.
Optionally, referring to fig. 4, fig. 4 is a second flowchart of an interface invoking method for identifying a parsing node according to the embodiment of the present application, where before step S12, the method further includes:
and step S13, removing the parsing interface with the first round-trip delay exceeding the preset range.
In this embodiment, before sorting the parsing interfaces, the parsing interfaces with an excessive first round trip delay or an abnormal response may be removed. For example, if the preset range is (1 ms to 20 ms), all the analysis interfaces whose first round-trip delay is not within 1ms to 20ms need to be screened.
Optionally, in this embodiment, before step S12, the method further includes: and if the current first round-trip delay of each analysis interface exceeds the preset range, re-executing each analysis interface of the identification analysis node to which the prefix of the acquired target identification belongs, and determining the current round-trip delay of each analysis interface as the first round-trip delay of the analysis interface.
It should be noted that, in this embodiment, the recursion resolution node may obtain all resolution interfaces of the identification resolution node once every 30 minutes, within the 30 minutes, the recursion resolution node may receive multiple identification resolution requests, and call the corresponding resolution interfaces to process the identification resolution requests, and after the processing is completed, update the round trip delay of the called resolution interfaces. After 30 minutes, the recursive analysis node re-acquires all the analysis interfaces identifying the analysis node, and re-calculates the first round-trip delay of each analysis interface.
Optionally, in an implementation manner of this embodiment, after updating the round trip delay of the invoked parsing interface each time, the parsing interface with the excessively large round trip delay or an abnormal response may be removed first, and the sorting may be performed based on other parsing interfaces from which the round trip delay abnormal or excessively large parsing interface is removed. At this time, it may happen that the resolution interface list is already empty before the time of reacquiring all resolution interfaces of the identification resolution node (i.e., when 30 minutes has not been reached), in which case, even if the time interval from the last acquisition of all resolution interfaces of the identification resolution node is less than 30 minutes, the recursive resolution node may still actively send a request to acquire all resolution interfaces of the identification resolution node.
In another implementation manner of this embodiment, if the first round trip delay of all the parsing interfaces exceeds the preset range, which indicates that the first round trip delay of the parsing interfaces is not accurate enough, at this time, the step corresponding to S11 needs to be executed again.
To sum up, the embodiment of the present application provides an interface calling method, an interface calling device, and an electronic device for an identifier resolution node, where the method is applied to a recursive resolution node in an identifier resolution system, where the recursive resolution node is in communication connection with the identifier resolution node, and first obtains each resolution interface of the identifier resolution node to which a prefix of a target identifier belongs, and determines a current round-trip delay of each resolution interface as a first round-trip delay of the resolution interface; when an identifier analysis request aiming at the target identifier is received, calling a first analysis interface in each analysis interface to process the analysis request according to the magnitude relation of the first round-trip delay of each analysis interface, wherein the first analysis interface is different from a second analysis interface called aiming at the identifier analysis request last time. According to the method and the device, when the analysis interface is called every time, calling can be carried out according to the size relation of the first round-trip delay of each analysis interface, and the first analysis interface called this time and the second analysis interface called last time are not the same, so that the balanced load of each analysis interface is guaranteed, and the overlarge pressure of a single analysis service interface is avoided.
