All Implemented Interfaces:

LinkLoadStrategy, TmLoadComputer

public class OverlayStrategy
extends LinkLoadStrategyAdapter
implements LinkLoadStrategy

Implement the overlay strategy. With this method, the traffic will be routed on a MPLS tunnel if the [source, destination] pair matches the [ingress, egress] pair of the tunnel. If several tunnels matches, the routed path is chosen arbitrarily among them. If no tunnel matches, it is routed via SPF (eventually using ECMP).

Method Detail

compute

public double[] compute(Domain domain,
                        TrafficMatrix tm)
                 throws NoRouteToHostException,
                        RoutingException

Compute the link load of the specified traffic matrix on the domain

Specified by:

compute in interface TmLoadComputer

Parameters:

domain - the domain

tm - the traffic matrix to route

Returns:

the load of each link as an array of double

Throws:

NoRouteToHostException - occurs if there is no route from a source to a destination

RoutingException - occurs if the routing algorithms encounter a error

equals

public boolean equals(java.lang.Object o)

Specified by:

equals in interface LinkLoadStrategy

Overrides:

equals in class LinkLoadStrategyAdapter

hashCode

public int hashCode()

Specified by:

hashCode in interface LinkLoadStrategy

Overrides:

hashCode in class LinkLoadStrategyAdapter
