All Implemented Interfaces:

LinkLoadComputer

public class OptDivideTMLoadComputer
extends AbstractLinkLoadComputer

This class implements a Traffic Engineering method which consist to divide the traffic matrix into N sub-matrices (called strata). Each stratum is routed independently of each other. Concerning the implementation of such solution, it is possible to establish multiple MPLS full-mesh (N) or to use the Multi-Topology functionality (N multiple topologies).

public OptDivideTMLoadComputer(Domain domain,
                               TrafficMatrix tm)

Method Detail

isECMP

public boolean isECMP()

setECMP

public void setECMP(boolean ECMP)

recompute

public void recompute()

Description copied from interface: LinkLoadComputer

Recomputes the load data.

establishFullmeshes

public void establishFullmeshes()
                         throws NoRouteToHostException,
                                RoutingException

Throws:

NoRouteToHostException

RoutingException

computeOptimumApproximation

public double computeOptimumApproximation()

setObjectiveFunction

public void setObjectiveFunction(java.lang.String objectiveFunction)
                          throws ObjectiveFunctionException

Throws:

ObjectiveFunctionException

setObjectiveFunction

public void setObjectiveFunction(TEObjectiveFunction objectiveFunction)

setN

public void setN(int N)

setVerbose

public void setVerbose(boolean verbose)

getTrafficMatrices

public java.util.List<TrafficMatrix> getTrafficMatrices()

Description copied from interface: LinkLoadComputer

TODO: maybe change this to a set Returns the traffic matrix.

Returns:

getShortName

public java.lang.String getShortName()

Description copied from interface: LinkLoadComputer

Return a string representing the parameters in short.

Returns:

equals

public boolean equals(java.lang.Object o)

Description copied from interface: LinkLoadComputer

returns true if the LinkLoadComputer uses the same parameters as the object o. (the computed data at a given moment are equivalent)

Specified by:

equals in interface LinkLoadComputer

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Specified by:

hashCode in interface LinkLoadComputer

Overrides:

hashCode in class java.lang.Object

getData

public LoadData getData()

Description copied from interface: LinkLoadComputer

Returns a view of the data. The returned data are still used internally.

Returns:

detachData

public LoadData detachData()

Description copied from interface: LinkLoadComputer

Returns the data used by the link load computer and do not use it internally any more. After the data has been detached, the load has to be computed again by a call to LinkLoadComputer.recompute().

Returns:

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
