Method Detail

getLoad

double[] getLoad()

Returns an newly created array that represent links load. For each link lnkof class Link in the domain, the corresponding load is located at the index domain.getConvertor().getLinkId(lnk.getId()) of the returned array.

Returns:

links load for all links in the domain.

getLoad

double getLoad(Link link)

Returns the load calculated for the given link or 0 if the link is not found.

Parameters:

link -

Returns:

Return the load calculated for the given link.

getUtilization

double[] getUtilization()

Returns an newly created array that represent links utilisation (link load / link cpacity). For each link lnkof class Link in the domain, the corresponding utilisation is located at the index domain.getConvertor().getLinkId(lnk.getId()) of the returned array.

Returns:

links load for all links in the domain.

getUtilization

double getUtilization(Link link)

Returns the utilisation calculated for the given link or 0 if the link is not found.

Parameters:

link -

Returns:

Return the utilisation calculated for the given link.

getDroppedTrafficMatrix

TrafficMatrix getDroppedTrafficMatrix(Node node)

Returns a new traffic matrix whose value for (src, dst) corresponds to the traffic dropped by node node when routing traffic from src to dst.

Parameters:

node -

Returns:

getDroppedTrafficMatrix

TrafficMatrix getDroppedTrafficMatrix()

Returns a new traffic matrix whose value for (src, dst) corresponds to the total dropped traffic when routing traffic from src to dst.

Returns:

getDroppedTraffic

double getDroppedTraffic(Node node)

Gets total traffic dropped at node node.

Parameters:

node -

Returns:

getDroppedTraffic

double getDroppedTraffic()

Gets the total dropped traffic.

Returns:

addListener

void addListener(LoadDataListener listener)

Adds a listener that signals change in the data.

Parameters:

listener -

removeListener

void removeListener(LoadDataListener listener)

Remove a listener.

Parameters:

listener -

notifyDataChange

void notifyDataChange()

Tells all the listeners that data has changed.
