Systems and methods are provided for dynamic name resolution in a distributed software-defined network. An fxDeviceApp registers service metadata with a centralized application manager that maintains authoritative deployment information. A name resolution service receives requests to resolve service names and identifies active instances of the requested services based on real-time deployment state. The name resolution service then returns corresponding network addresses, enabling service-to-service communication within and across network zones. The system supports localized caching, zone-specific resolution rules governed by policy managers, and dynamic updates in response to changes in application deployment. Resolution decisions may account for service health or load metrics, and service lookup requests may be handled using a standardized message format compatible with a virtual messaging fabric. These features enable reliable, scalable, and policy-aware service discovery for distributed applications deployed across heterogeneous execution environments.

Methods for traffic redirection, corresponding terminal, controller, authorization server, name resolution servers and computer program. A name resolution method implemented in a terminal connected to a communication network includes: transmitting, to a first name resolution server, a name resolution message via a secure communication channel between the terminal and the first name resolution server; if a redirection of the DNS traffic of the terminal is authorized, obtaining at least one identifier of a second name resolution server for the redirection; and executing at least one action for managing the redirection of the DNS traffic of the terminal to the second name resolution server, at least from among: verifying legitimacy of the second name resolution server, sending an indication of a failure of a connection of the terminal with the second name resolution server; and requesting deactivation of the redirection of the DNS traffic to the second name resolution server.

Systems, methods, devices, and computer readable storage media described herein provide techniques for simplifying data access and management for data computing. In an aspect, a request to load data is received. The request comprises an aliased name associated with the data. A call is transmitted to a name resolution service executing on a computing device. The call comprises the aliased name and is configured to cause the name resolution service to identify the data associated with the aliased name. A response is received from the first resolution service. The response comprises metadata of the data. The data is obtained from a data source based on the metadata. A dataset is generated based on the obtained data. A response to the request is provided. The response comprises the generated dataset. In a further aspect, an application is configured to import a library into a computer program under development.

The method and device for identifying DoH service, the electronic device and the storage medium are disclosed, wherein the method comprises: sending a first domain name resolution request to a domain name resolution server at a preset detection frequency, the first domain name resolution request being used to request a DoH-based domain name resolution service for a first detection domain name; updating a target network address corresponding to the first detection domain name in a database according to each first resolution result; comparing a network address in the database with a network address to be queried in a domain name resolution service type query request when the domain name resolution service type query request is received; and determining that the domain name resolution service in the domain name resolution service type query request is the DoH-based domain name resolution service when there is a network address same as the network address to be queried in the database.

The invention discloses a domain name resolution method and device oriented to multiple network planes, and belongs to the technical field of domain name resolution. A service sends a domain name resolution request to a domain name resolution service; after receiving the request, the domain name resolution service checks whether a corresponding address in a validity period is stored in an equipment cache according to a resolution type; and when the analysis type is A and AAAA types, if the IPv6 address exists in the cache, returning the address to the service, and if the IPv4 address exists in the cache, returning the IPv6 address inquired by the DNS server to the service or returning the IPv4 address in the cache to the service when the IPv6 address is still not inquired in an overtime state. According to the method and the device, each service of the terminal equipment can customize the resolution type and the timeout duration according to own requirements, whether the corresponding IP exists in the cache of the equipment or not is inquired before polling the DNS server, the IP in the cache is directly returned when the target IP is not polled in a short time, the domain name resolution efficiency is optimized, and the user experience is improved.

The invention relates to traffic redirection methods, a corresponding terminal, controller, authorization server, name resolution servers, and software. The invention relates to a name resolution method, implemented in a terminal (51) connected to a communication network, comprising: transmitting (511) a name resolution message to a first name resolution server via a secure communication channel between the terminal (51) and the first name resolution server; if DNS traffic redirection from the terminal is authorized, obtaining (512) at least one identifier of a second name resolution server for such redirection; and executing (513) at least one action to manage the redirection of DNS traffic from the terminal to the second name resolution server, including at least: verifying the legitimacy of the second name resolution server.- Send an indication of a connection failure between the terminal and said second name resolution server, - Request the deactivation of said DNS traffic redirection to said second name resolution server.

This invention relates to a method and system for accessing public cloud computing resources using a hybrid approach of the internet and dedicated lines. The method logically divides the user's data flow to the public cloud into control data flow and business data flow. It utilizes the internet to complete control operations such as resource requests, while simultaneously establishing point-to-point dedicated line connections between the supply and demand ends via physical optical cables and relay nodes. By planning independent / 30 subnet mask interconnection address segments and configuring routing strategies, this invention achieves logical isolation and mutual access between the business network segment and the original internal LAN. By deploying a domain name resolution service on the client side, it wildcard resolves the domain name of the computing instance to a private network IP, ensuring that business data is transmitted via dedicated lines. Compared with existing technologies, this invention, through the separation of control flow and business flow, retains the convenience of internet access while using dedicated lines to solve the inefficiency problem of large-scale data interaction under GPU computing power demands. The independent interconnection segment planning ensures non-intrusiveness to the user's existing network architecture and avoids the waste of IP address resources.

The application provides a method and device for deploying a domain name resolution service, electronic equipment and a storage medium. The method comprises: generating an rpm package according to the processor architecture and kernel version of a target server and uploading the rpm package to a yum source; selecting a deployment node, adding the IP address, hostname and login password information of the target server to the hosts file of the deployment node; installing each service relied on by the domain name resolution service on the target server according to the yum source; generating and running a network configuration file based on an ansible var variable file and a template file; running a monitoring script and starting preprocessing before starting the domain name resolution service when the network configuration file is found; starting an nginx component process, specifying a config file and a log saving path; generating a fast_cgi component configuration file and starting a fast_cgi component process; starting a named component process in response to monitoring that the network configuration file exists; and configuring the interface IP address, route and vxlan.
