Introduction:
In the Q-Balancer solution, Path Monitoring is a core component working in conjunction with Dynamic Path Selection. The Path Monitoring constantly monitors the status of WAN links, and based on its measured result, the appliance is able to intelligently failover and distribute traffic across all available links.
> In the diagram below, there are two WAN links. WAN 1 is the primary line, while WAN 2 is the secondary. The Q-Balancer appliance performs path monitoring based on the status of target IP and its tcp port 80.
> In case the Q-Balancer appliance is unable to connect the target IP via tcp 80, then the link is considered a faulty link.
> Traffic will then be transparently diverted to the secondary WAN (WAN 2) until the primary WAN (WAN 1) recovers from the outage.
> As Path Monitoring is an object in the Q-Balancer appliance, navigate to Objects > Path Monitoring to complete its configuration.
