Summary of the application
The industrial internet identification resolution system is an important component of an industrial internet network system, is a neural center for supporting interconnection and intercommunication of the industrial internet, and has the function similar to a domain name resolution system (DNS) in the field of the internet. The identification analysis system is one of core infrastructures for safe operation of the global industrial internet, and by endowing each object with a digital identification, cross-region, cross-industry and cross-enterprise information query and sharing are realized by means of the industrial internet identification analysis system.
The core of the industrial internet identification analysis system comprises identification codes, an identification analysis system and an identification data service. Wherein:
1. identification coding: machine, article "ID card".
2. An identification analysis system: the unique positioning and information query of the machine and the article are carried out by utilizing the identification, which is the premise and the basis for realizing the accurate butt joint of a global supply chain system and an enterprise production system, the full life cycle management of products and the intelligent service.
3. Identification data service: the industrial identification data management and the data sharing and sharing among enterprises, industries, regions and countries can be carried out by means of the identification coding resources and the identification analysis system.
The identifier resolution technology refers to a process of mapping an object identifier to information required by an actual information service, such as an address, an article, a spatial location, and the like. For example, by resolving the identity of an item, the address of the server storing its associated information can be obtained. The identification analysis is a technical process of 'information conversion' capable of accurately and efficiently acquiring information corresponding to the object identification in a complex network environment.
The industrial internet identification analysis system stores the tracing and positioning information of each stage in a database of each enterprise to form a distributed data storage mode; the information is inquired through the identification analysis system, so that the authenticity and authority of the information are effectively improved. Based on an industrial internet identification analysis system, an anti-tampering and credible identification 'ID card' is given to an article, on one hand, data of the product dispersed in each business system from different stages of raw materials, design, production, quality detection, package storage, logistics transportation, marketing channels and the like can be connected, and data interconnection and intercommunication of the whole supply chain are realized. On the other hand, the identification analysis service can be used for tracing the information of each link of the product from the direction of a consumer and inquiring the information of the data source.
The traditional industrial internet identification analysis system comprises a top level node, a second level node and an enterprise node from top to bottom. The top level node is used as the top level identification service node of the country, is in butt joint communication with international nodes and various second-level industry nodes in China, provides national identification analysis service, identification record, identification authentication and other management capabilities, and is a core resource and facility of an identification analysis system; the secondary node provides identification code registration and identification analysis service for industries or regions, and completes related identification service management, identification application docking and the like. Its main functions include: the management of coding rules and technical standards realizes the functions of data management, identifier registration, identifier analysis and infrastructure guarantee, provides the applications including supply chain management, full life management, product tracing and the like, and carries out standardized agreement on operation management monitoring interfaces, network communication interfaces, data transmission formats and the like between top-level nodes and enterprise nodes through interface specifications. The enterprise node can register the identification for the enterprise entity and the virtual asset by accessing the identification analysis system, and performs unique positioning and information query on the resource according to the identification.
The recursive node directly provides service for individual users, the users send the identification analysis request to the recursive node, the recursive node inquires the attributive secondary node and initiates the identification analysis request to the recursive node, the address of the corresponding enterprise node is fed back to the recursive node after the secondary node is analyzed, the recursive node initiates the identification analysis request to the enterprise node, and the recursive node returns the analysis result returned by the enterprise node to the users after receiving the analysis result.
However, when an enterprise node fails to provide an identifier resolution service, because the entire identifier resolution system lacks detection and handling measures for the situation, after the recursive node obtains the address of the enterprise node to which the identifier belongs from the secondary node, it still sends an identifier resolution request to the recursive node and waits for the identifier to give a resolution result, and at this time, it is inevitable that a response of the enterprise node cannot be received.
In view of the above technical problems, the present application provides an identifier parsing method, which employs a detection mechanism for abnormal enterprise nodes, periodically detects whether each enterprise node is abnormal by a secondary node, updates a pre-stored routing table according to the abnormal detection result, when the secondary node receives the identification resolution request which is sent by the recursion node and carries the target identification code, firstly, judging whether the target enterprise node corresponding to the target identification code is abnormal or not according to the routing table, if the enterprise address is abnormal, the enterprise resolved address corresponding to the target enterprise node is not returned to the secondary node, but rather sends a default packet to the secondary node indicating that the target enterprise node is anomalous, because the recursive node receives the preset data packet instead of the enterprise analysis address, the secondary node cannot always send an identification analysis request to the abnormal enterprise node, and further the occurrence of the crash condition of the recursive node can be avoided. After receiving the preset data packet, the recursive node directly returns preset prompt information to the query terminal to prompt the user that the data packet cannot be analyzed currently, so that the user experience is improved.
Having described the general principles of the present application, various non-limiting embodiments of the present application will now be described with reference to the accompanying drawings.
Example 1:
the embodiment provides an identifier resolution method, which is applied to a secondary node, and as shown in fig. 1, the method includes:
step S102: and periodically detecting whether each enterprise node is abnormal or not, and updating a pre-stored routing table according to an abnormal detection result.
In this embodiment, an unexpected exit or a failure of an enterprise node may cause that the enterprise node cannot receive an identifier resolution request sent by a recursive node, and since the system cannot predict which enterprise node may accidentally exit or fail at a certain time, in order to timely find or sense the unexpected exit or the failure of the enterprise node, a secondary node performs periodic anomaly detection on all enterprise nodes connected to the secondary node.
Optionally, periodically detecting whether each enterprise node is abnormal, and updating a pre-stored routing table according to an abnormal detection result, which may specifically include:
sending an empty request packet to an enterprise node corresponding to each node identifier in a routing table at intervals of a preset time interval, and starting a preset first timer;
within the timing time of the first timer, if an empty response packet which is sent by a certain enterprise node and corresponds to the empty request packet is received, determining that the certain enterprise node is abnormal, otherwise, determining that the certain enterprise node is abnormal;
and marking the node state of the enterprise node which is determined to be abnormal in the routing table as normal, otherwise, marking the node state as abnormal.
In this embodiment, the preset time interval may be set as needed, for example, the time interval may be 3 minutes, 5 minutes, and the like, the routing table further preferably includes an IP address and a port number of each enterprise node, and the secondary node initiates polling to the enterprise nodes in the routing table according to the IP address and the port number, that is, sends an empty request packet to each enterprise node, and then waits for a response from the enterprise node. Meanwhile, the secondary node sets a timer to time the response of the enterprise node, the time for timing can be set to 30 seconds, if the enterprise node does not respond within 30 seconds, namely the secondary node does not receive the empty response packet of the enterprise node, the enterprise node is judged to be abnormal, otherwise, the enterprise node is not abnormal. It should be noted that, in order to save resources, the exception detection uses an empty request packet and an empty response packet, the packet bodies of the empty request packet and the empty response packet are empty, and the packet header format may include: a message sequence number, a message type, an originating node, etc., where the message type is used to indicate whether the packet is a request packet, a response packet, or a query packet.
Optionally, while periodically detecting whether each enterprise node is abnormal and updating the pre-stored routing table according to the abnormal detection result, the method may further include:
setting a second timer for each enterprise node, wherein the timing time of the second timer is less than the preset time interval;
and respectively starting a corresponding second timer for each enterprise node, marking the node state of the corresponding enterprise node in the routing table as abnormal if an empty query packet sent by the corresponding enterprise node is not received within the timing time of the second timer, and resetting the second timer to restart timing after the timing of the second timer is finished.
In this embodiment, in order to increase the speed of discovering an abnormal enterprise node, and in consideration of system efficiency and resource occupation (waiting for response), bidirectional detection is performed between the secondary node and the enterprise node, so that when a problem occurs in the detection mechanism of any one of the two nodes, the other node can compensate the problem. Specifically, the enterprise node also sends an empty query packet to the secondary node periodically without waiting for a response of the secondary node, the secondary node sets a timer for each enterprise node, the timing time is less than the period setting time for the secondary node to initiate polling, after the timing is finished, if the secondary node still does not receive the empty query packet of the corresponding enterprise node, the routing table is updated, the node state of the enterprise node is marked as abnormal, and if the empty query packet of the enterprise node is received before the timing is finished, the timing is restarted.
In this embodiment, the secondary node sets a timer for each enterprise node, which is similar to heartbeat detection, and the enterprise node is considered to be abnormal if no empty query packet is sent after the timing of the enterprise node is ended. And for the enterprise node marked as abnormal, once receiving the empty query packet sent by the enterprise node, the secondary node immediately updates the routing table and marks the node state as normal. Meanwhile, for the enterprise node marked as abnormal, the secondary node still periodically sends an empty request packet to the enterprise node, and if the enterprise node responds within the timing time, the secondary node immediately updates the routing table and marks the node state as normal.
Step S104: receiving an identification analysis request which is sent by a recursion node and carries a target identification code;
step S106: judging whether the target enterprise node corresponding to the target identification code is abnormal or not according to the routing table;
step S108: if so, sending a preset data packet for indicating the abnormality of the target enterprise node to the recursion node so that the recursion node returns preset prompt information to the query terminal.
In this embodiment, a user scans a two-dimensional code (or any other form such as a bar code) on an industrial product through a terminal to obtain a target identification code of the product, then initiates an identification analysis request to a recursive node for identification analysis of the industrial internet, after receiving the identification analysis request, the recursive node sends the identification analysis request to a secondary node, and the secondary node obtains a target enterprise node corresponding to the target identification code and judges whether the node state of the target enterprise node corresponding to a routing table is marked as abnormal; if yes, judging that the target enterprise node is abnormal. When the target enterprise node is abnormal, the secondary node sends a preset data packet to the recursion node, the body of the preset data packet can be empty, for example, the preset data packet can be an empty response packet, so as to indicate that the target enterprise node is abnormal, and when the recursion node receives the preset data packet, preset prompt information, such as 'current cannot be analyzed', is returned to the query terminal.
In this embodiment, if the target enterprise node corresponding to the target identification code is non-abnormal, the secondary node obtains an enterprise resolution address corresponding to the target enterprise node, and the routing table preferably further includes enterprise resolution addresses of the enterprise nodes. And the secondary node sends the acquired enterprise analysis address to the recursive node so that the recursive node sends a product analysis request to a target enterprise node corresponding to the enterprise analysis address, and the recursive node returns product analysis information to the query terminal after receiving the product analysis information sent by the target enterprise node based on the product analysis request.
In a specific embodiment, the identifier resolution method may include the following steps:
(1) the secondary node sets a routing table, which contains all enterprise node information accessed to the secondary node, including enterprise ID, enterprise URL, IP address and port number, and each enterprise node is additionally provided with a 'node state' field for marking whether the enterprise node is normal currently;
(2) the secondary node periodically (every 3 minutes) initiates polling to the enterprise nodes in the routing table, sends an empty request packet and then waits for the response of the enterprise nodes;
(3) setting a timer for the secondary node to time the response of the enterprise node, and if the enterprise node does not respond within 30 seconds, judging that the enterprise node is abnormal;
(4) the second-level node updates the routing table and marks the state of the enterprise node which does not send the null response packet on time as abnormal;
(5) synchronously, the enterprise node also sends an empty query packet to the secondary node periodically, and quitting without waiting for the response of the secondary node after the sending is finished;
(6) the secondary node sets a timer for each enterprise node, and after the timing is finished, the empty query packet of the enterprise node is not received, the routing table is updated, and the state of the enterprise node is marked as abnormal; if receiving the empty query packet of the enterprise node before timing is finished, restarting timing;
(7) for the enterprise node marked as abnormal state, once receiving the empty query packet sent by the enterprise node, the secondary node immediately updates the routing table and marks the state of the enterprise node as normal;
(8) for the enterprise node marked as the abnormal state, the secondary node still periodically sends an empty request packet to the enterprise node, if the enterprise node responds within 30 seconds, the secondary node immediately updates the routing table and marks the state of the routing table as normal;
(9) when the recursion node initiates an identification analysis request to the secondary node, the secondary node analyzes the corresponding enterprise ID, firstly, a routing table is searched, the current state of the enterprise node is inquired, and if the node state is normal, the secondary node normally returns the enterprise analysis address, namely the enterprise URL to the recursion node;
(10) if the node state is abnormal, the secondary node generates an empty response packet and returns the empty response packet to the recursion node;
(11) and the recursive node receives the response packet, checks and finds that the response packet is empty, and returns a prompt of 'current cannot be analyzed' to the query terminal.
By the method, the phenomenon that the analysis system rejects service due to the resource exhaustion of the recursion nodes can be avoided, and the normal operation of the analysis system is effectively guaranteed.
The method for analyzing the identifier provided by the embodiment of the invention comprises the steps that a secondary node periodically detects whether each enterprise node is abnormal or not, a prestored routing table is updated according to an abnormal detection result, when the secondary node receives an identifier analysis request which is sent by a recursion node and carries a target identification code, whether a target enterprise node corresponding to the target identification code is abnormal or not is judged according to the routing table, and when the judgment result is abnormal, an enterprise analysis address corresponding to the target enterprise node is not returned to the secondary node, but a preset data packet for indicating the abnormality of the target enterprise node is sent to the secondary node, so that the recursion node directly returns preset prompt information to a query terminal after receiving the preset data packet to prompt a user that the user cannot analyze the data currently, the protection of the recursion node is realized, and the problem that when the enterprise node fails to provide an identifier analysis service in the related technology is solved, due to the lack of detection and handling measures for the situation, the problems of resource exhaustion and service interruption of the recursive nodes are easily caused.
