Problems solved by technology

[0008] The query efficiency of the existing query technology is low. A domain name resolution requires the local domain name server to go through a one-way path from the root node to the final response node. After multiple network interaction processes, the low query efficiency may not be able to support higher requirements in the future. Netw...

Embodiment Construction

[0034] Throughout the description, the preferred embodiments and examples shown should be considered as exemplars of the invention and not intended to limit the scope of protection of the invention.

[0035] The embodiment of the present invention provides a method for domain name resolution, such as image 3 As shown, change the iterative query method of domain name resolution to a flat structured method, specifically:

[0036] 310. The local DNS server receives the DNS query message from the query host, and obtains the domain name in the DNS query message. The local DNS server is pre-configured on the query host, and the query host can directly send DNS query messages to its local DNS server.

[0037] 320. According to the domain name, it is judged whether a location identifier or an identity identifier corresponding to the domain name is locally stored. The corresponding relationship between the domain name and the location identifier or identity identifier stored by the ...

Abstract

The invention discloses a domain name resolving method comprising: acquiring position identification or identity of remote DNS server corresponding to domain name to be inquired by storing corresponding relation between management area and position identification or identity of global domain name server, changing the iteration inquiry mode for resolving traditional domain name to flat structure. The invention also discloses a domain name resolving system and a device, promotes domain name resolving efficiency, further reduces dependence on root domain name server.

Description

technical field [0001] The present invention relates to domain name resolution technology, in particular to a domain name resolution method, system and device. Background technique [0002] On a TCP / IP network, computers use IP addresses for addressing, but IP addresses are not intuitive and easy to remember. People prefer to use meaningful names to find a computer, such as www.huawei.com. Therefore, it is necessary to provide a mechanism to realize the conversion between the computer name and the computer IP address, and the domain name resolution system (Domain Name System, hereinafter referred to as DNS) came into being. [0003] DNS is a database of distributed architecture, which is stored on DNS servers distributed all over the world. The DNS database forms a tree, and at the top of the tree is the root (ROOT) domain name server. Such as figure 1 As shown, the organizational structure of the DNS database is an inverted tree. Each node in the tree has a label. Among t...
