The RoundRobinAvailabilityChainer establishes a load balancing solution, using information from the Availability Checker daemon. The Availability Checker daemon monitors the servers if they are up or down, and based on that information the RoundRobinAvailabilityChainer can automatically target the next available host in up state. The RoundRobinChainer connects to hosts in an order based on the information from the Availability Checker daemon. Use the RoundRobinAvailabilityChainer together with the DirectedRouter.
