Problems solved by technology

[0004] However, the inventor found through research that in most cases, the new version of the DNS zone file has little data difference compared to the old version of the DNS zone file, and the real-time encoding and compression technology has caused the new version of the DNS zone file to be fully distributed and needs to regenerate a large number of repeated DNS networks Data packets consume a lot of CPU resources and memory resources, increase the transfer cost of DNS zone files, and result in low zone transfer performance of DNS zone files

Embodiment Construction

[0055] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiment of the application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the application. Obviously, the described embodiment is only It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0056] As a typical distributed system, DNS uses zone transfer to synchronize data between nodes at all levels. The performance of zone transfer determines the data synchronization performance of DNS. The update operation is likely to occur during the full delivery of the DNS zone file, and the new version of the DNS zone file is obtained based on the old version o...

Abstract

The invention discloses a multi-version DNS zone file full-amount issuing method and device, and the method comprises the steps: obtaining a new-version DNS zone file in a full-amount issuing process,receiving a new full-amount issuing request, and determining a resource record, related to an updating operation, from an old-version DNS file to the new-version DNS zone file as a target resource record; based on the target resource record, the updating operation corresponding to the target resource record and the data transmission block set corresponding to the old version DNS zone file, obtaining a multiplexing data transmission block and a new data transmission block to form a data transmission block set corresponding to the new version DNS zone file; and according to the new full-amountissuing request, issuing a data transmission block set corresponding to the new-version DNS area file in a full-amount manner. Data transmission blocks in a data transmission block set corresponding to an old version DNS zone file are multiplexed to the maximum extent based on update operation resource records involved in the new version DNS zone file, and resource consumption of a CPU and a memory is reduced.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a method and device for delivering full volume of multi-version DNS zone files. Background technique [0002] With the rapid development of computer science and technology, Internet services have gradually penetrated into various fields of society, and their applications in various fields have become more and more extensive. The number of global Internet domain names is very large and increasing day by day. Domain Name System (English: Domain Name System, abbreviation: DNS) as the management and analysis system of global Internet domain names, due to its typical distributed characteristics, realizes data synchronization between nodes at all levels The area transfer method is adopted, therefore, the area transfer performance becomes the key point to realize high-speed data synchronization. [0003] At present, the full distribution of DNS zone files refers to th...
