      public WDMLink​(int id, int src, int dst, double delay, double weight, int wavelengths, int bw, double pc)

  • Method Details

    • getBandwidth

      public int getBandwidth()

    • getPc

      public double getPc()
      Retrieves Power comsumption of this wavelengths in this link
      Returns:

    • getWavelengths

      public int getWavelengths()
      Retrieves the number of available wavelengths for a given WDMLink.
      Returns:
      the value of the WDMLink's wavelengths attribute

    • isWLAvailable

      public java.lang.Boolean isWLAvailable​(int wavelength)
      Says whether or not a determined wavelength is available.
      Parameters:
      wavelength - the index number of the wavelength that will be checked for availability in the WDMLink's freeWavelengths vector
      Returns:
      true if the wavelength is available

    • hasWLAvailable

      public int[] hasWLAvailable()
      Retrieves the list of all available wavelengths in a given WDMLink.
      Returns:
      list of available wavelengths

    • firstWLAvailable

      public int firstWLAvailable()
      Retrieves the lowest available wavelength in a given WDMLink.
      Returns:
      first true item in the freeWavelengths vector

    • amountBWAvailable

      public int amountBWAvailable​(int wavelength)
      Retrieves how much bandwidth is available for a determined wavelength.
      Parameters:
      wavelength - for which available bandwidth will be verified
      Returns:
      amount of available bandwidth

    • hasBWAvailable

      public int[] hasBWAvailable​(int bw)
      Retrieves the list of wavelengths that have a determined amount of bandwidth available.
      Parameters:
      bw - the minimum bandwidth required
      Returns:
      vector of integers with the retrieved wavelengths

    • reserveWavelength

      public boolean reserveWavelength​(int wavelength)
      By attributing false to a given wavelength inside the freeWavelengths vector, this function "reserves" a wavelength.
      Parameters:
      wavelength - value of the wavelength to be reserved
      Returns:
      true if operation was successful, or false otherwise

    • releaseWavelength

      public void releaseWavelength​(int wavelength)
      By attributing true to a given wavelength inside the freeWavelengths vector, this function "releases" a wavelength.
      Parameters:
      wavelength - value of the wavelength to be released

    • addTraffic

      public int addTraffic​(int wavelength, int bw)
      Inside a given wavelength, decreases, if possible, the available bandwidth. Therefore, this is equivalent to adding traffic to the network.
      Parameters:
      wavelength - value of the wavelength where traffic will be added
      bw - amount of bandwidth to be allocated
      Returns:
      the remaining available bandwidth after operation

    • removeTraffic

      public int removeTraffic​(int wavelength, int bw)
      Inside a given wavelength, increases, if possible, the available bandwidth. Therefore, this is equivalent to removing traffic from the network.
      Parameters:
      wavelength - value of the wavelength from where traffic will be removed
      bw - amount of bandwidth to be released
      Returns:
      the remaining available bandwidth after operation

    • getLinkUtilization

      public double getLinkUtilization​(int wavelength)

    • getFreeWavelengths

      public int getFreeWavelengths()
      Retrieves the number of available wavelengths that have space in the its bandwidth, given WDMLink.
      Returns:
      the number of avaiable free wavelengths

    • toString

      public java.lang.String toString()
      Description copied from class: Link
      Prints all information related to the Link object.
      Specified by:
      toString in class Link
      Returns:
