Novel caching method and system for industrial Internet identifier analysis recursive server

Abstract

The invention relates to the technical field of industrial Internet identifier analysis and networks, in particular to a novel caching method and system for an industrial Internet identifier analysisrecursive server. An original caching method of the recursive server is not changed, and the identifier and the information with higher query frequency can be dynamically adjusted to the caching queueuntil the identifier is deleted due to expiration of TTL or discarded due to the fact that the caching queue reaches the upper limit of the length. Meanwhile, a newly-built secondary node cache queueis used for caching IP address information corresponding to the secondary node, so whether the secondary node cache queue has a secondary node address or not can be checked if the recursive server has no cache locally, and if the secondary node cache queue has the secondary node address, a request is directly initiated to the secondary node to obtain corresponding identification information, so that interaction operation with a top-level node is reduced, thereby reducing the top-level node pressure and bandwidth load. According to the method, the frequency of frequently interacting with the top-level node can be reduced, and the working efficiency of industrial Internet identifier analysis caching can be improved.

Description

Technical field[0001]The invention relates to a new type of caching method and system for a recursive server for industrial Internet identification analysis, and belongs to the technical field of industrial Internet identification analysis and networking.Background technique[0002]The industrial Internet identification resolution system is similar to the Internet domain name resolution system (DNS), just like the "dictionary" of industrial Internet equipment. On the public Internet, users can access the website by entering the URL with the help of the DNS domain name resolution system. In the Industrial Internet, users can access servers that store relevant information about machines, materials, parts, and products through the industrial Internet identification analysis system. The entire industrial Internet identity analysis architecture system includes top-level nodes, secondary nodes, recursive nodes and enterprise nodes.[0003]The industrial Internet logo resolution recursive serv...

Problems solved by technology

[0004] Since the enterprise logo registration information is stored in the secondary node, it can be seen from the above conventional caching process that when the recursive server has no cached results or the cache expires, it needs to interact with the top-level node to obtain the IP address corresponding to the secondary node. A large number of applications of identification resolution will cause recursive nodes to frequently interact with top-level nodes, causing top-level nodes to respond to pressure
