Method Details

getNumWavelengths

public int getNumWavelengths()

Retrieves the number of wavelengths in a given PhysicalTopology.

Returns:

the value of the PhysicalTopology's wavelengths attribute

createPhysicalLightpath

public void createPhysicalLightpath(LightPath lightpath)

Specified by:

createPhysicalLightpath in class PhysicalTopology

removePhysicalLightpath

public void removePhysicalLightpath(LightPath lightpath)

Specified by:

removePhysicalLightpath in class PhysicalTopology

canCreatePhysicalLightpath

public boolean canCreatePhysicalLightpath(LightPath lightpath)

Specified by:

canCreatePhysicalLightpath in class PhysicalTopology

getBWAvailable

public int getBWAvailable(LightPath lightpath)

Specified by:

getBWAvailable in class PhysicalTopology

addRate

public void addRate(int rate, LightPath lightpath)

Specified by:

addRate in class PhysicalTopology

getBW

public int getBW(LightPath lightpath)

Specified by:

getBW in class PhysicalTopology

usedConverters

public int usedConverters(WDMLightPath lightpath)

Retrieves the number of wavelength converters a given LightPath object uses.

Parameters:

lightpath - the LightPath object

Returns:

the number of converters the lightpath uses

getWeightedGraph

public WeightedGraph getWeightedGraph(int wvl, int bw)

Returns a weighted graph with vertices representing the physical network nodes, and the edges representing the physical links. The weight of each edge receives the same value of the original link weight if the wavelength wvl in that link has at least bw Mbps of bandwidth available. Otherwise it has no edges.

Parameters:

wvl - the wavelength id

bw - the amount of bandwidth to be established

Returns:

an WeightedGraph class object

canAddRate

public boolean canAddRate(int rate, LightPath lightpath)

Specified by:

canAddRate in class PhysicalTopology

removeRate

public void removeRate(int rate, LightPath lightpath)

Specified by:

removeRate in class PhysicalTopology
