Problems solved by technology

[0004] (1) The offload gateways in the existing network transmission are mostly fixed offload, and there are few special scenarios where real-time switching occurs. Once the offload is configured to a certain network, it is rarely changed later, and most of the changes are during non-terminal business periods, such as at night. The terminal DNS record timeout triggers DNS query again, and there is no problem
[0005] (2) If the offload gateway in the existing network transmission supports real-time switching of links, there will be a problem of terminal business failure due to DNS misalignment

Abstract

The present invention provides a method, device, computer storage medium and equipment for switching offload gateway links. The method includes: receiving a non-DNS message from a terminal; and judging whether the target IP of the non-DNS message matches the current link If described target IP does not match with current link, then obtain the redirection IP that matches with current link; Adopt described redirection IP to replace the target IP of described non-DNS message, based on described redirection IP, all The non-DNS packet is forwarded to the network side. The invention solves the problem that terminal services are blocked due to short-term dislocation of IP addresses and new links, and ensures the continuity of network service access and improves the switching experience of terminal customers by switching links without perception.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a link switching method, device, computer storage medium and equipment of a distribution gateway. Background technique [0002] In the field of network transmission, there is often a problem that a certain network load is too large and needs to be shunted, and the shunt gateway plays the role of converging data, shunting and guiding. However, when the distribution networks to be selected belong to different ISPs (Internet Service Providers, Internet Service Providers), such as one China Mobile and one China Unicom. The IP addresses corresponding to the services of a certain ASP (Application Service Provider, application service provider) on the two networks may be different. After the terminal successfully queries the DNS (Domain Name System, Domain Name System) for the first time, if the record does not time out, it will not query again. During this perio...
