Link scheduling method and apparatus thereof

Abstract

An embodiment of the invention discloses a link scheduling method and an apparatus thereof. The method comprises the following steps that a domain name system DNS agent server receives a first DNS request message carrying domain name information, and then determines a resource pool corresponding to the domain name information acquired from a load balancing LB equipment request, wherein the resource pool includes at least one link information; from the at least one link information included by the resource pool, target link information is determined and a first DNS response message carrying a target link IP address corresponding to the target link information is sent to a client. In the embodiment of the invention, load sharing of a link under the condition that the client uses a domain name system DNS agent is realized.

Description

technical field [0001] The present invention relates to the field of information communication technologies, in particular to a link scheduling method and device. Background technique [0002] In a typical application network based on DNS (Domain Name System, domain name system) link load sharing, when the client, as an external Internet user accessing the intranet server, accesses the intranet server (that is, the server that provides data services), its current Some workflows are as follows: first, the client sends a DNS request message to the local DNS server (as a DNS proxy server), where the DNS request message contains domain name information; the local DNS server sends the DNS request message generated according to the DNS request message Another DNS request message is sent to LB device (Load Balancing Device, link load balancing device, hereinafter referred to as LB device); the LB device selects the optimal link from multiple links according to the preset scheduling...
