The method for reducing packet loss rate during switching of network port binding active-standby links according to claim 1, wherein updating the IP address of the standby network device to the virtual IP address and updating the network configuration of the standby network device based on the active-standby link switching operation signal to realize the network connection of the standby link comprises:
and sending a main link switching operation signal to the execution device so as to facilitate the network switching operation of the execution device.
5. The method for reducing packet loss rate during switching between active and standby links bound to a network port according to claim 1, wherein the main link switching operation signal is transmitted to the execution device through network information or broadcast messages.
6. The method for reducing packet loss rate during handover of a portal binding primary and secondary link of claim 1, wherein updating the network configuration of the secondary network device comprises updating network routing information.
7. The method for reducing packet loss rate during switching of network port binding active-standby links according to claim 1, wherein the method is characterized in that based on the active-link reverse switching operation signal, the IP address of the active network device is updated to a virtual IP address, and the network configuration of the active network device is updated to realize the active network connection; comprising the following steps:
and sending a main link reverse switching operation signal to the execution equipment so as to facilitate the network switching operation of the execution equipment.
8. A test system for reducing packet loss rate when switching network port binding main and standby links is characterized by comprising: the system comprises a configuration module, a main network module, a standby network module, an execution device and a monitoring module;
the configuration module is used for configuring the main network equipment and the standby network equipment and distributing a shared virtual IP address to the main network equipment;
