Problems solved by technology

[0003] like figure 1 Shown is a schematic diagram of the master server and the slave server in the prior art, all slave servers download zone files from the master server, the disadvantages of this method are: a), the bandwidth pressure of the master server is very high, because all slave servers Both can only download zone files from the master server, resulting in greater pressure on the bandwidth of the master server, and may affect other normal services of the master server; b), the time-consuming transfer of existing zone files is relatively long. The upload bandwidth of the master server is used to transfer the zone files, and the upload bandwidth of other slave servers is not used, resulting in a large transmission delay of the zone files; c), low bandwidth utilization, in the existing scheme, once the zone files are updated Suspended because the link is temporarily unavailable, and needs to be restarted when the next zone file is retransmitted, resulting in low bandwidth utilization

Embodiment Construction

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. It should be understood that the described embodiments are only some of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

[0040] The present invention mainly proposes the technical scheme related to the master server and the slave server in the DNS authoritative server. In the scheme explained in the present invention, the master and slave servers need to increase several functional modules on the existing basis, specifically as follows: master server It is necessary to add a DNS zone file segmentation module and a slave server management module, such a...

Abstract

The invention relates to a DNS zone file multi-node transmission method and system. A DNS zone file segmentation module and a slave server management module are added to a master server. The method includes the steps: (1) a plurality of authority servers including the master server and a plurality of slave servers are deployed in a DNS system, the master server periodically produces DNS zone files and sends the DNS zone files to the slave servers; (2) after the DNS zone files are segmented on the master server, file subblocks are numbered, and a slave server list is generated according to register information on the master server; (3) the master server sends a zone file update command to the slave servers in the slave server list and meanwhile sends the slave server list to the slave servers; (4) the slave servers pick neighbor nodes after receiving the update command and load the multi-node file subblocks after the neighbor nodes are selected to complete transmission of the DNS zone files.

Description

technical field [0001] The invention relates to a method for transmitting DNS zone files, in particular to a method and system for multipoint transmission of DNS zone files, and belongs to the field of DNS system data transmission. Background technique [0002] The DNS system is the most important Internet basic resource. It consists of authoritative servers, recursive servers, and clients. The authoritative server is responsible for storing files in the zone for queries by recursive servers and clients, and is the source of DNS information. The recursive server is responsible for receiving the request sent by the client (parser), and then sends query requests to authoritative servers at all levels to obtain the query results required by the user, and finally returns to the client's parser. The client can directly request resource records from the authoritative server, but generally queries various resource records through the recursive server to improve the response speed. ...
