Embodiment Construction

[0043] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0044] The basic idea of ​​the present invention is: dynamically apply for memory in the ENUM-DNS server, and set a hash table and a search tree in the memory, the nodes of the hash table store the non-numeric part of the domain name and its corresponding search tree position, The nodes of the search tree store the numerical part of the domain name and the corresponding position of the domain name data area. In this way, the resource records corresponding to the domain name can be quickly located when querying the domain name, and at the same time, millions of resource records can be loaded in a sh...

Abstract

The method comprises: in memory, applying a domain name data area and a resource record data area for each domain; each domain comprises at least one domain name; in the memory, setting up at least one harsh table and a search tree; the node of harsh table saves non-digital portion of the domain name and its corresponding search tree location; the node of the search tree saves the digital portion of the domain name and its domain name data area location; dynamically applying the resource records, saving the initial resource records corresponding to each domain name into the domain name data area, and saving the resource records corresponding to each domain name into the resource records data area. The invention also provides a phone number mapping domain name server thereof.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a memory processing method and processing device of a Telephone Number Mapping (TelephoneNumber Mapping, ENUM) domain name server (Domain Name System, DNS). Background technique [0002] Telephone Number Mapping (ENUM) is a protocol defined by the Internet Engineering Task Force (IETF) - RFC 2916. It uses a domain name server (Domain Name System, DNS) mechanism to combine the E.164 number with a service resource based on the DNS architecture, that is, a Uniform Resource Identifier (Uniform Resource Identifier, URI). [0003] The international standard adds a new domain name e164.arpa to the DNS system to store the URIs of each resource, establishes the mapping between E.164 numbers and accessible resources, and provides a way for telephone numbers to access resources. The accessible resources may include telephone (Phone), electronic mail (Email), fax (Fax) and so...
