Problems solved by technology

[0005] 1. Manual execution of update delivery will cause cumbersome operations for managers, and the probability of errors in manual execution is high. Once an error occurs, it may lead to unpredictable consequences
[0006] 2. Rely on third-party software for updates. Although the reliability has been improved, the controllability is poor, and the performance and safety cannot be guaranteed

Embodiment Construction

[0034] The present invention is mainly composed of three parts: transmission of area file update information, message server cluster, and sub-node area file update. Such as figure 1 shown.

[0035] The main function of sending zone file update information is that the master node extracts the analysis data from the authoritative analysis database and sends it to the message server in the form of a message; that is, the master node converts the update of the analysis database into a zone file update message and sends it to the message server. The zone file update information transmission is mainly composed of the following modules: analysis data extraction module, analysis data preprocessing module, message assembly module, and message sending module. Such as figure 2 shown.

[0036] Analysis data extraction module: mainly extracts several pieces of analysis update data from the authoritative analysis database. There is a data table in the authoritative analysis database to ...

Abstract

The invention discloses a safe and reliable DNS (Domain Name System) zone file information issuing updating method and system, belonging to the computer network technical field. The method comprises the following steps that: a main node regularly extracts a batch of data from an authoritative analytic database; after preprocessing, the update information of the zone file is delivered to a message server in the form of a message; the message server issues the update information of the zone file to each sub-node orderly and separately and simultaneously keeps the same in the database; and after all the sub-nodes confirm completion of updating, the message is deleted from the database. The system comprises a main node, a plurality of sub-nodes and a message server cluster; the message server cluster is in communication connection with the main node and the sub-nodes through the network, respectively. Compared with the prior art, the method and the system provided by the invention are capable of ensuring the succession and correction of update issuing of the zone file and have high controllability.

Description

technical field [0001] The invention relates to a safe and reliable method and system for sending and updating DNS zone file information, belonging to the technical field of computer networks. Background technique [0002] Domain Name System (Domain Name System, DNS) is an important Internet infrastructure, including a distributed database that can map domain names and IP (Internet Protocol, Internet Protocol) addresses to each other, and realize the IP address conversion function that domain names and networks can recognize software system. DNS contains the syntax used to define the host names used on the Internet according to a hierarchical structure, as well as the authorization rules for names, and all the settings that the system needs to make in order to define the correspondence between names and IP addresses. In fact, DNS is a distributed database. It allows local control of various parts of the entire database; at the same time, the entire network can also access ...
