Description
Technical Field
The invention relates to stability analysis of a control system, in particular to a method for determining the effective range of uncertainty factors when the control system contains the uncertainty factors.
Background
The overall deployment architecture of the industrial internet identification in China mainly comprises a national top-level node, a secondary identification analysis node and a double-layer multi-node. By 4 months in 2020, the China identity service network has the construction scale of 5 national top-level nodes and 86 secondary service nodes. The industrial internet identification analysis system in China is built on the basis of the technical scheme of a Handle identification analysis system.
The overall deployment architecture of the Handle identification resolution system has a distributed double-layer service structure, as shown in fig. 1. The top layer of the system is composed of Global Handle Register (GHR), the lower layer is composed of Local Handle Service (LHS), and the top layer corresponds to a national top-level node and a secondary identification analysis node in the national industrial internet identification overall deployment architecture. The Global Handle Register (GHR) manages Service domain information (identification prefix) and server information (query Service IP and port of the server) of a lower Layer Handle Service (LHS). The Local Handle Service (LHS) stores server information (query Service IP and port of the server) of a Global Handle registration Service (GHR) in an upper layer and identification data information for managing the Service domain, and names of the identification data have the same identification prefix. Each Handle service (GHR/LHS) consists of one or more sites (sites). Stations within the same service domain maintain data synchronization. Each site consists of one or more servers (servers), which are physical devices that store Handle identification data. The Handle's query request is ultimately directed to these servers.
The Handle identity resolution system provides a recursive query function for querying identity data.
The query flow of the recursive query function is as follows:
after a server in the identifier resolution system obtains a query request message, firstly, whether the query request message belongs to a service domain managed and stored by a Local Handle Service (LHS) corresponding to a site where the server is located is judged. When the request is in the management range of the service domain, the result can be inquired in the service domain and immediately responded to the user. When the request is not in the service domain management range, firstly, a request for inquiring management Handle service (LHS) of a corresponding domain needs to be initiated to a top-level global Handle registration service (GHR), after a service IP and a port of the management Handle service (LHS) of the corresponding domain are obtained, a query request with specific identification is initiated to the service IP and the port of the handling Handle service (LHS) again to obtain result data.
With the popularization and application of industrial internet in China, the scale of the future secondary service node can be continuously developed. And a secondary node providing query service only stores the identification data of the management domain of the node. When a user sends a query request to a server in the identifier resolution system, the server needs to query the service address of the second-level node of the administrative domain where the request is located from the national top-level node for a very high probability. Then, an identification query request is sent to the management domain service address, and the result can be obtained. In the currently established service network, 5 national top-level nodes need to respond to the management domain real-time query of 86 secondary service nodes, which causes waiting of terminal query users. Therefore, a recursive query route optimization method for accelerating the recursive query process to obtain results needs to be researched.

Example 2
Based on the above query routing device, the present application further provides an industrial internet identifier resolution recursive query routing method, which includes:

Firstly, a configuration file of a node server management identification domain is designed, and each line in the file represents a physical server to which a service node belongs and the identification domain managed by the physical server. Because each service node can be distributed to deploy a plurality of physical sites, each physical site can have a plurality of physical servers, one identification domain may correspond to a plurality of physical servers providing query services. With the development of the identification service network, secondary node service information which is not added into the configuration file in time is continuously generated, and the configuration design provides service configuration of national top nodes (identification management domain fields are identified by using "+" marks) and service configuration of secondary nodes.

Fig. 3 shows an example of node server management identity domain configuration, packet classification, and a classified information pool structure.
And after the identification analysis system is started, loading the configuration of the management identification domain of the secondary node server and classifying the configuration. The integrated management domain is defined as a group of a top node services of a country corresponding to the class a services, and the integrated management domain is marked by a mark in a configuration file.

And finally, when the identification analysis system receives a query request of a user and needs to carry out recursive query, judging the affiliated identification management domain according to the queried identification prefix, and selecting corresponding server group information in the analysis node server group information pool. And selecting the matched b-type server group information and a-type server group information for recursive query. Most query requests can obtain result data by querying the class b server group once, and a few query requests without valid class b server group information need to query the class a service. And missing or updating invalid b-type server group information is added in the inquiry process of using the a-type service information, and the analysis node server group information pool of the identification analysis system is perfected. Every time the operation of inquiring the information of the b-type server group from the a-type server is successfully carried out, the information of one b-type server group is added or updated, and all inquiry requests of the subsequent b-type server group skip the steps. And finally, the purpose of improving the recursive query speed of the identification analysis system is achieved. The execution flow of the recursive query route optimization method is shown in fig. 4:
1) the system receives the inquiry request;
2) and analyzing the request, and matching and judging whether the request identifier belongs to a known b-type service management domain. If yes, carrying out the flow of the step 3, otherwise, carrying out the flow of the step 5;
3) using the matched b-type service information to perform result query;
4) and waiting to judge whether a query result is obtained. If yes, the flow of the step 10 is carried out, otherwise, the flow of the step 5 is carried out;
5) querying by using the configured class a service information, and querying the service information of the class b service to which the current request belongs;
6) and judging whether the class a service returns the class b service information to which the request identifier belongs. If yes, carrying out the flow of the step 7, otherwise, carrying out the flow of the step 11;
7) using newly obtained b-type service information to carry out result query;
8) and waiting to judge whether a query result is obtained. If yes, carrying out the flow of the step 9, otherwise, carrying out the flow of the step 11;
9) updating the b-type service information to which the request identifier belongs;
10) and returning the obtained result data to the user, and ending the recursive query process.
11) And returning that the result data does not exist to the user, and ending the recursive query process.
As a preferred embodiment of the present scheme, in the system startup phase, a configuration file for managing an identification domain is loaded, and configuration information in the configuration file is used to initialize an identification domain management structure in an information pool; in the system operation stage, the identification management server which can not normally provide the query in the initialization information pool is deleted in the recursive query service, the identification management server which can provide the query and is automatically found in the recursive query process is added, and the identification domain management structure in the identification resolution node server group information pool is continuously improved and updated.
