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 invention provides a shunting gateway link switching method, a shunting gateway link switching device, a computer storage medium and an apparatus. The method includes the following steps that: a non-DNS message from a terminal is received; whether the target IP of the non-DNS message is matched with a current link is judged; if the target IP is not matched with the current link, a redirected IP that is matched with the current link is obtained; and the target IP of the non-DNS message is replaced with the redirected IP, and the non-DNS message is forwarded to a network side on the basis ofthe redirected IP. With the shunting gateway link switching method, the shunting gateway link switching device, the computer storage medium and the apparatus of the invention adopted, the problem ofthe unavailability of terminal service due to the short-term misalignment of an IP address and a new link can be solved; links can be switched without being sensed; and therefore, the continuity of network service access is ensured, and terminal customer switching experience can be improved.

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...
