Constructor Detail

LinkTrafficMatrix

public LinkTrafficMatrix(LinkLoadData linkData)

Parameters:

linkData - The structure containing all info about link (SNMP way)

Method Detail

setElement

public void setElement(int orig,
                       int dest,
                       double value)
                throws NotYetImplementedException

This method is used to set a cell in the link tm

Parameters:

orig - the int id of the orig link (id is the same as in the linkLoadData structure)

dest - the int id of the dest link (id is the same as in the linkLoadData structure)

value - the value to set

Throws:

NotYetImplementedException

setElement

public void setElement(java.lang.String orig,
                       java.lang.String dest,
                       double value)

Parameters:

orig - the id of the orig link

dest - the id of the dest link

value - the value to set

length

public int length()

As the traffic matrix is square only one dimension is needed

Returns:

the length of one dimension of the matrix

convertToNodeTM

public TrafficMatrix convertToNodeTM(Domain domain)
                              throws InvalidDomainException,
                                     NodeNotFoundException

This method convert the link traffic matrix in a node traffic matrix

Parameters:

domain - the domain where the tm is computed

Returns:

the trafic matrix with node as source and destination

Throws:

InvalidDomainException

NodeNotFoundException

print

public void print()

This method print the link traffic matrix
