Abstract
Description
technical field
[0001] The invention relates to the field of network detection, in particular to a real-time automatic switching device and method applied to route interruption. Background technique
[0002] At present, most of the existing Linux firewalls do not support the next-hop link continuity detection function. When the main link is interrupted, the default route cannot be automatically switched to the backup link because the port is still up. If the cost is too high by purchasing a dedicated firewall, the existing general-purpose x86 firewall based on Linux system is conducive to saving costs, but this solution generally has the following disadvantages:
[0003] 1) The general x86 firewall does not support the link continuity detection function due to the Iptables software of Linux;
[0004] 2) When the main link is interrupted, the default route cannot be transferred to the backup link, resulting in service termination; Contents of the invention
[0005] The ob...
