Differentiated reliability (DiR) in WDM rings without wavelength converters

  title={Differentiated reliability (DiR) in WDM rings without wavelength converters},
  author={Andrea Fumagalli and Marco Tacca},
The concept ofDifferentiated Reliability (DiR) was recently introduced by the authors to provide multiple reliability degrees (or classes) at the same network layer u sing a common protection mechanism, e.g., path switching. According to the DiR concept, each connection at the layer under consideration is guaranteed a minimum reliability degree, defined as theMaximum Failure Probabilityallowed for that connection. The reliability degree chosen for a given connection is thus determined by the… CONTINUE READING
