Abstract

The embodiment of the invention discloses a method, a system and a domain name resolution server for realizing load balancing of a network server. The method comprises: the healthy states of various network servers are monitored, according to the healthy states, the IP address of the network agreement of the network server which exists in the IP list in the domain name resolution DNS server and cannot be visited is deleted, or the address is set as invalid; the DNS server receives the request that network users visit the network server, selects the IP address from the valid IP addresses of the IP list that the request is corresponding to, and the network server which owns the selected IP address provides the network service for the network users. By applying the invention, allocating the network users to a server down can be avoided, allocating the network users to the network server which can be visited can be guaranteed, thus helping the network users to obtain the network service.

Description

technical field

[0001] The invention relates to the Internet field, in particular to a method, a system and a domain name resolution server for realizing network server load balancing. Background technique

[0002] For a set of network servers composed of multiple network servers in a symmetrical manner, each network server has an equivalent status and can provide external services independently without the assistance of other network servers. Implementing network server load balancing refers to evenly distributing the requests sent to the network server set to the network servers in the network server set, so that the loads of the various network servers are balanced among each other.

[0003] Currently, a domain name resolution (DNS) server is a commonly used load balancer. As we all know, A records are stored in the DNS server, and in the A records, each domain name corresponds to an IP list, and the IP list includes the IP addresses of all network servers corresponding ...
