Abstract

The invention discloses a network switching method and system based on a dual redundant system, and a storage medium. The method comprises the following steps: standby equipment monitors a routing table entry and an ARP table entry of main equipment; when the main equipment adds or deletes the routing table entry and the ARP table entry in the process of establishing communication with the user host, the standby equipment synchronously adds or deletes the same table entry; and after the dual-computer redundant system is switched, the standby equipment has routing table entries and ARP table entries on which the communication with the user host is established, and the standby equipment becomes new main equipment to finish the switching of network communication. According to the method, after the dual redundant system is switched, the original standby equipment has the routing table entry and the ARP table entry which are depended on for establishing communication with the user host without operating the routing protocol and the ARP protocol after being changed into the new main equipment, so that the switching of network communication is quickly completed.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a network switching method, system and storage medium based on a dual-machine redundant system. Background technique [0002] Telecommunications equipment requires extremely high availability of business services. When developing and designing, it is necessary to take into account that functional modules such as the operating system, drivers, and hardware resources of the equipment can quickly restore normal business services. Therefore, the industry has widely used two relatively An independent device system provides a set of business service functions. One of the device systems is in an active state and provides business services, which is called the master device; the other device system is in an inactive state and does not provide business services. It is called it for spare equipment. When the primary device fails, it can quickly switch to the backup device to...
