A method and device for delivering full volume of multi-version DNS zone files

Abstract

This application discloses a method and device for delivering full-volume multi-version DNS zone files. The method includes: if a new version of DNS zone files is obtained during the process of full-volume delivery, and a new full-volume delivery request is received, the old version of DNS files is determined to be transferred to the new version. The resource record involved in the update operation of the version DNS zone file is the target resource record; based on the target resource record, the update operation corresponding to the target resource record, and the data transmission block set corresponding to the old version DNS zone file, the multiplexed data transmission block and the new The data transfer block forms a data transfer block set corresponding to the new version of the DNS zone file; according to the new full-volume delivery request, the full-volume delivery of the data transfer block set corresponding to the new version of the DNS zone file. Based on the resource records involved in the update operation in the new version of the DNS zone file, the data transmission blocks in the data transmission block set corresponding to the old version of the DNS zone file are reused to the maximum extent to reduce the resource consumption of CPU and memory.

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...

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
