Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings, but this is not intended to limit the present invention.

[0021] see figure 1 , the embodiment of the present invention provides a DNS-based data optimization method, the method comprising:

[0022] Establish monitoring nodes in different data centers to periodically obtain the service performance of each data center;

[0023] Select the DNS server with the best service performance from the above data centers;

[0024] The IP address of other DNS data in the monitoring node is modified, and the domain name query request is directed to the selected DNS server with the best service performance.

[0025] Specifically, the above-mentioned monitoring nodes can be set up in various big cities, one or more data service centers can be set up in each big city, and multiple monitoring nodes can be set up close to ...

Abstract

The invention belongs to the field of computer technologies and discloses a data optimization method based on a DNS (Domain Name Server). The method comprises the following steps of establishing monitoring nodes at different data centers and periodically obtaining server performance of each data center; selecting a DNS server with the optimal service performance from the data centers; and modifying IP addresses of other DNS data in the monitoring nodes and guiding a domain name query request to the selected DNS server with the optimal service performance. The method solves the problems of low load balancing performance and service quality for domain name resolution in the original DNS load balancing system.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a DNS-based data optimization method. Background technique [0002] The earliest load balancing technology was realized through random name resolution in DNS service. In a DNS server, the same name can be configured for multiple different addresses, this data is sent to other name servers, and clients that eventually query for the name will randomly use one of the addresses when resolving the name. Therefore, for the same name, different clients will get different addresses, so different clients access web servers with different addresses, so as to achieve the purpose of load balancing. [0003] At present, in the F5 large-scale load balancing (3DNS / GTM) solution proposed by F5 Corporation of the United States, 3DNS and GTM products mainly address the needs of large enterprises and companies across data centers or across Internet access links. Common application scenarios incl...
