Method Detail

inferTM

TrafficMatrix[] inferTM(Domain domain,
                        LinkLoadData snmp,
                        RoutingMatrix[] a,
                        java.util.HashMap<java.lang.String,java.lang.String> params)
                        throws NotYetImplementedException,
                               InvalidDomainException,
                               TrafficMatrixAlreadyExistException,
                               NodeNotFoundException,
                               InvalidTrafficMatrixException

This method is implemented for each new tomography method. Need the same number of routing matrix than snmp vectors or only one routing matrix for all the snmp vector

Parameters:

domain - the domain where we want to compute the traffic matrix

snmp - A data structure containing all info about link (snmp data based)

a - vector of the routing matrix associated with the method, each element is a matrix at a time depending of the index

params - list of parameter particular to the tomograhy method

Returns:

a serie of estimated traffic matrix, one for each snmp data

Throws:

NotYetImplementedException

InvalidDomainException

TrafficMatrixAlreadyExistException

NodeNotFoundException

InvalidTrafficMatrixException
