Embodiment Construction

[0021] figure 1 It is a flowchart of an embodiment of the data processing method of the present invention, such as figure 1 As shown, the method includes:

[0022] Step 100, the local DNS server stores the mapping information of the domain name and the IP address obtained by querying other DNS servers into the cache cache unit in the local storage module;

[0023] The user terminal sends a domain name query request including a domain name to the local DNS server, and the local DNS server first queries the information storage unit in the local storage module according to the domain name, and if the IP address corresponding to the domain name is obtained, the IP address is returned to the user terminal; if Do not find the IP address corresponding to the domain name from the information storage unit, then query the cache memory unit in the storage module, if the IP address corresponding to the domain name is obtained, then return the IP address to the user terminal; If the IP a...

Abstract

The present invention provides a data processing method, device and system, wherein the method includes: the local DNS server stores the mapping information of the domain name and the IP address acquired by querying other DNS servers into a cache unit in the local storage module; If it is judged that the preset storage period is reached, the mapping information of the domain name and the IP address stored in the storage period in the cache memory unit is backed up to the centralized storage module, so that after the local DNS server is initialized, the centralized storage module will The mapping information between the domain name and the IP address is re-imported to the cache cache unit for obtaining the corresponding IP address from the cache cache unit according to the domain name. Through the data processing method, device and system provided by the present invention, after the DNS server is initialized, the validity and stability of the system are guaranteed, the performance of resolution is improved, and the consumption of bandwidth is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a data processing method, device, and system. Background technique [0002] Since there is a one-to-one (or many-to-one) relationship between domain names and IP addresses on the Internet, a domain name must correspond to an IP address, but an IP address does not necessarily have a domain name. Although domain names are easy for people to remember, machines can only communicate with each other. Therefore, the domain name system (Domain Name System, DNS) server uses a hierarchical structure similar to a directory tree to perform domain name resolution operations that map domain names to IP addresses. When the user terminal sends a domain name query request to the local DNS server, the local DNS server will first query the locally stored database. If there is no corresponding IP address, it will send a query to the upper-level DNS server and re...
