This invention provides a method for providing CNI support for a Docker container engine, relating to the field of container runtime technology. The method includes configuring a custom runtime component docker-cni in the Docker container engine; specifying the custom runtime component docker-cni as the runtime when creating a container and setting it to a network-free mode (none); injecting a pre-start hook and a stop hook into the container's configuration file during the container creation phase; the hooks are used to trigger the custom runtime component docker-cni to perform CNI network operations; when the container starts and triggers the pre-start hook, calling the CNI plugin's add network operation according to the command injected in the pre-start hook to complete the container network configuration; when the container stops and triggers the stop hook, calling the CNI plugin's delete network operation according to the command injected in the stop hook to clean up the container network configuration.

The application discloses a signature key centralized management method and system based on a blockchain, relates to the technical field of blockchain management, and comprises the following steps: reading a port mounting state, screening a signature key from the port mounting state, and performing standardized coding to generate a blockchain bindable state; reading a current authorization range abstract, constructing a current field binding relationship abstract, comparing the current field binding relationship abstract with a binding relationship abstract, determining an abnormal level, generating a signature link abnormal positioning result, and generating a controlled recovery permission mark; determining a controlled recovery action to be executed this time, executing the controlled recovery action, and re-reading a field connection state after the action is completed; reading a chain binding relationship abstract to generate a post-recovery binding relationship abstract, comparing the post-recovery binding relationship abstract with the binding relationship abstract, and combining an action execution result and an executed recovery action to generate a signature service recovery result.

The invention relates to the technical field of software-defined network configuration, in particular to a software-defined network configuration method and system, comprising: receiving a user service request, and generating service features and service quality requirements through natural language processing and feature extraction, generating a network slicing strategy containing a binding relationship between a resource reservation parameter and a path based on a service level agreement mapping rule and network topology state information, and converting the network slicing strategy into an equipment-independent general configuration instruction based on a unified data model, and compiling the general configuration instruction into an equipment special instruction which can be executed by equipment of different manufacturers, issuing the equipment special instruction to target network equipment through a southbound interface of the SDN controller, receiving configuration confirmation information returned by the equipment, and verifying the configuration confirmation information so as to ensure that the equipment runs according to the service quality requirement. According to the invention, business demand analysis standardization, resource allocation refinement, equipment instruction unification and configuration execution verifiability can be realized, and the controllability and reliability of the SDN network are improved.

The application belongs to the technical field of sampling scheduling, and particularly relates to a limited random sampling scheduling method and system under a communication degradation scenario, comprising: obtaining historical participation record statistical parameters; expanding the capacity of an expert sampling pool according to a historical maximum avoidance rate to determine an expansion multiple, and setting the maximum sampling round to a single round; randomly extracting a supervision sample subset from an independent supervision candidate pool; applying an avoidance constraint label to the candidate nodes in the expanded expert sampling pool according to the historical participation record, and generating a random sequence through a concurrent safe random permutation algorithm; sequentially screening the nodes without the avoidance constraint label from the random sequence, and adding them in sequence until the target number of extracted people is reached to form an expert sample subset; and aggregating the supervision sample subset and the expert sample subset to generate a sampling result list. Thus, the problems of high networking dependence, poor constraint adaptation, no pre-checking, poor isolation of supervision roles, and race conflicts under high concurrency in the prior art are solved.

The application discloses a Tomcat container application thread pool isolation method and device based on Java Agent and a medium, relates to the Java technical field, and comprises the following steps: loading an agent program through a Java Agent mechanism when a Tomcat container starts, and initializing a global application thread pool manager by the agent program; performing byte code conversion on a network request processing class of the Tomcat container through the agent program, and inserting routing code in a request processing method of the network request processing class; creating a corresponding independent thread pool for each Web application deployed in the Tomcat container through the application thread pool manager; obtaining a Web application identifier to which an HTTP request belongs through the routing code when the HTTP request is received; obtaining the corresponding independent thread pool from the application thread pool manager according to the Web application identifier; and submitting a processing task of the HTTP request to the obtained independent thread pool for execution, and preventing the processing task from being executed in an original shared thread pool of the Tomcat container, so that the Tomcat container can be used to non-invasively realize the application thread pool isolation in the Tomcat container.
