Class FailOverStrategy<S extends ClientRequest>

java.lang.Object

com.cisco.oss.foundation.loadbalancer.AbstractLoadBalancerStrategy<S>

com.cisco.oss.foundation.loadbalancer.FailOverStrategy<S>

All Implemented Interfaces:

LoadBalancerStrategy<S>, Serializable

public class FailOverStrategy<S extends ClientRequest>
extends AbstractLoadBalancerStrategy<S>

This is the FailOverStrategy implementation. This implementation relies on an active passive deployment mode. If one server is down all the requests will be done with the other server. If they are both down an exception will be thrown.
