Abstract

The present invention provides a link load balancing method and device The method comprises: obtaining the domain name carried in a DNS response message when a load balancing device receives the DNS response message sent by a DNS server, and the DNS response message is used for replying the message of an IP address corresponding to the domain name required by the DNS request message; determining whether the domain name matches a configured specific domain name in advance or not; if domain name matches a configured specific domain name in advance, generating a dynamic item, wherein the dynamic item includes the IP address corresponding to the domain name carried by the DNS response message; when receiving the data message sent by a user terminal, inquiring the dynamic item according to the object IP address of the data message; and if there is provided an IP address being the same as the object IP address of the data message in the dynamic item, forwarding the data message through a specific link. Through adoption of the embodiment of the invention, the link load balancing method and device are able to optimize the load balancing effect.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a link load balancing method and device. Background technique [0002] Link load balancing technology is a technology that improves the experience of internal network users accessing external network links. It solves the problem of cross-operator access when internal network users access external network links through the principle of proximity, and solves the problem through link detection technology. Egress link reliability problem. [0003] Because some specific sites need to be accessed through specific links, in view of the above problems, in the existing link load balancing scheme, when the destination IP (Internet Protocol, Internet Protocol) address of the traffic from the internal network to the external network does not belong to the domestic address segment, Both are forwarded through a specific link (the link corresponding to a specific service ...
