DNS zone file full-amount issuing method and device

Abstract

The invention discloses a DNS zone file full-amount issuing method and device, and the method comprises the steps: loading an index region of a target DNS zone file which is pre-coded into a network data format based on a text format DNS zone file to a memory based on a target full-amount issuing request, and obtaining a DNS message index list; and traversing the DNS message index list based on the target full-amount issuing request, and issuing each DNS message in the data area of the target DNS area file to the network equipment by adopting a zero-copy technology in sequence. Visibly, the area file in the text format is pre-coded into a network data format which can be directly issued in a full amount, and repeated analysis and coding are not needed to improve the DNS data processing performance; the target DNS zone file is issued by combining the zero copy technology, the data copy of the DNS message is eliminated, the kernel space and the user space do not need to be switched, theoperation cost of the DNS is reduced, and the method is suitable for a high-concurrency full-amount issuing scene.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a method and device for delivering all 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 huge and increasing day by day. Domain Name System (English: Domain Name System, abbreviation: DNS) is the management and resolution system of global Internet domain names, and its data processing performance is the focus of attention in the field of Internet infrastructure construction. [0003] Since DNS is a typical distributed system, zone transfer is generally used to complete data synchronization between nodes at all levels. Therefore, the performance of zone transfer determines the data synchronization perform...

Problems solved by technology

[0005] After research, the inventor found that in the high-concurrency and full-volume delivery scenario, a large number of repeated parsing and encoding operations are required, which will consume a large amount of CPU resources and cause a sharp decline in DNS data processing performance; and in the process of delivering DNS network data messages Environment switching and data copying involving kernel space and user space, as well as data copying between kernel space and socket buffer, also consume a lot of CPU resources, which increases the operating cost of DNS

Therefore, the consumption of a large amount of CPU resources in the high-concurrency full-volume delivery scenario not only reduces the data processing performance of DNS but also increases the operating cost of DNS
