Constructor Detail

TrafficGenerator

public TrafficGenerator(int ASID,
                        TrafficModel model,
                        double fraction)

Deprecated.

TrafficGenerator

public TrafficGenerator(TrafficModel model,
                        RoutingMatrix matrix)

Deprecated.

Initialises a newly created TrafficGenerator object. All the pairs of nodes will generate traffic.

Parameters:

model - The traffic model to be used.

matrix - The routing matrix to be used.

TrafficGenerator

public TrafficGenerator(TrafficModel model,
                        RoutingMatrix matrix,
                        double fraction)

Deprecated.

Initialises a newly created TrafficGenerator object.

Parameters:

model - The traffic model to be used.

matrix - The routing matrix to be used.

fraction - The fraction of the pairs of nodes that must generate traffic.

Throws:

java.lang.IllegalArgumentException - If fraction is equal to or lower than 0 or greater than 1.

Method Detail

getKey

public final int getKey(int src,
                        int dst)

Deprecated.

getIds

public final IntPair getIds(int column)

Deprecated.

isGenerateOnlyEdgeTraffic

public boolean isGenerateOnlyEdgeTraffic()

Deprecated.

Get the generateOnlyEdgeTraffic property value If generateOnlyEdgeTraffic is true, the generator generates traffic for nodes of type EDGE only otherwise it generates traffic for all pairs of nodes

Returns:

the generateOnlyEdge property value

setGenerateOnlyEdgeTraffic

public void setGenerateOnlyEdgeTraffic(boolean generateOnlyEdgeTraffic)

Deprecated.

Set the generateOnlyEdgeTraffic property value. If generateOnlyEdgeTraffic is true, the generator generates traffic for nodes of type EDGE only otherwise it generates traffic for all pairs of nodes

Parameters:

generateOnlyEdgeTraffic -

generate

public void generate()
              throws TrafficGenerationException

Deprecated. generateTM()

Generates traffic for TopologyManager.getInstance().getDomain() using model. This method ensures that the capacity of the links is sufficient. If this is not the case, it regenerates traffic. If after MAX_TRIALS, the method didn't arrive to generate traffic, it throws a TrafficGenerationException. Note that if fraction < 1, the pairs that generate traffic are selected randomly (using an uniform distribution).

Throws:

TrafficGenerationException

generateTM

public TrafficMatrix generateTM()
                         throws InvalidDomainException,
                                NodeNotFoundException,
                                NoRouteToHostException,
                                RoutingException,
                                DataConsistencyException

Deprecated.

Throws:

InvalidDomainException

NodeNotFoundException

NoRouteToHostException

RoutingException

DataConsistencyException

getFraction

public double getFraction()

Deprecated.

Returns the fraction of the pairs of nodes that will generate traffic.

getMatrix

public RoutingMatrix getMatrix()

Deprecated.

Returns the routing matrix of this traffic generator.

getTraffic

public double[] getTraffic()

Deprecated.

Returns the generated traffic. Let's name the returned array traffic. traffic[i] designates the traffic between the pair of nodes i. The ids of the pair of nodes i can be found using getMatrix().getIds(i).

Throws:

java.lang.IllegalStateException - If generate was not called, or if fraction is too small.

getLinkCounts

public double[] getLinkCounts()

Deprecated.

Returns the link counts vector.

Throws:

java.lang.IllegalStateException - If generate was not called, or if fraction is too small.

setFraction

public void setFraction(double fraction)

Deprecated.

Sets the fraction of the pairs of nodes that will generate traffic.

Throws:

java.lang.IllegalArgumentException - If fraction is equal to or lower than 0 or greater than 1.
