Domain	getDomain()
void	setSamplingParams(int minutes, int samplingRate) Use samping rate and minutes to convert the data from netflow.

InterDomainTrafficMatrixGeneration

public InterDomainTrafficMatrixGeneration(Domain domain,
                                          int minutes,
                                          int samplingRate)

Method Detail

useRaw

public void useRaw()

If raw is true, sampling rate and minutes won't be used. Data will be in bytes per period. see setSamplingParams(int, int) if you want to use sampling rate and minutes.

setSamplingParams

public void setSamplingParams(int minutes,
                              int samplingRate)

Use samping rate and minutes to convert the data from netflow.

Parameters:

minutes -

samplingRate -

getDomain

public Domain getDomain()

generateXMLTrafficMatrixfromNetFlow

public TrafficMatrixFile generateXMLTrafficMatrixfromNetFlow(java.lang.String NETFLOWbaseDirectory,
                                                             java.lang.String NETFLOWdirFileName,
                                                             java.lang.String[] suffixes,
                                                             java.lang.String XMLTrafficMatrixFileName)
                                                      throws java.lang.Exception

This function reads NetFlow aggregated data and stores them in one XML inter-domain traffic matrix file. If raw is true, the data will be represented in bytes per period. Otherwise, it will be converted in the units of the domain. The generated traffic matrix will be saved in the file XMLTrafficMatrixFileName.

Parameters:

NETFLOWbaseDirectory - the base directory containing aggregated NetFlow data

NETFLOWdirFileName - directory and filename of the NetFlow aggregated data (found in NETFLOWbaseDirectory/id/ or NETFLOWbaseDirectory/rid/)

suffixes - an array of potential suffixes for filenames

XMLTrafficMatrixFileName - the name of the generated inter-domain XML traffic matrix

Returns:

the inter domain traffic matrix

Throws:

java.lang.Exception

generateXMLTrafficMatrixfromNetFlow

public TrafficMatrixFile generateXMLTrafficMatrixfromNetFlow(java.lang.String NETFLOWbaseDirectory,
                                                             java.lang.String NETFLOWdirFileName,
                                                             java.lang.String[] suffixes)
                                                      throws java.lang.Exception

This function reads NetFlow aggregated data and stores them in one XML inter-domain traffic matrix file. If raw is true, the data will be represented in bytes per period. Otherwise, it will be converted in the units of the domain.

Parameters:

NETFLOWbaseDirectory - the base directory containing aggregated NetFlow data

NETFLOWdirFileName - directory and filename of the NetFlow aggregated data (found in NETFLOWbaseDirectory/id/ or NETFLOWbaseDirectory/rid/)

suffixes - an array of potential suffixes for filenames

Returns:

the inter domain traffic matrix

Throws:

java.lang.Exception
