Problems solved by technology

When the amount of updated data is too large, the incremental area data information in the log file of the incremental area data will also be large, and it is difficult to quickly query the incremental area data involved (the bind application reads the entire incremental area data file, Then traverse the entire incremental area data to query the operable incremental area data), which in turn affects the efficiency of IXFR (incremental area transfer)
Especially when the amount of data in the incremental area has exceeded the range that can be tolerated, when the incremental area data is compressed, the compression speed will be very slow due to the large log file, which will affect the DNS dynamic update rate of the entire network
It can be seen that a fast method of querying and compressing DNS incremental zone data files is particularly important, which directly affects the dynamic update speed of the DNS system, affects the correct query efficiency of DNS, and affects the application development of the Internet

Abstract

The invention provides a processing method of a DNS (Domain Name Server) incremental zone data file. The processing method comprises the following steps: step 101, establishing index data information of DNS incremental zone data; step 103, storing the index data information into an index file and establishing associated information of an index data file and the incremental zone data file; and step 105, carrying out file processing according to the associated information. By adopting the method provided by the invention, the efficiency of dynamically updating a DNS can be improved and the accuracy of DNS lookup services is improved.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method for processing DNS incremental zone data files. Background technique [0002] DNS (Domain Name System, Domain Name System), a distributed database on the Internet as a mapping between domain names and IP addresses, enables users to access the Internet more conveniently, without having to remember IP numbers that can be directly read by machines. The process of finally obtaining the IP address corresponding to the host name through the host name is called domain name resolution (or host name resolution). [0003] Incremental region data compression in IXFR (incremental region transfer) refers to a reduction operation for incremental region data files. [0004] The Internet (that is, the network through the use of the TCP / IP protocol) is becoming more and more dynamic today. In order to adapt to this change, DNS needs to provide the function of dynamically adding and deleting re...
