Efficient Algorithms for Wavelength Converter Placement in All-optical Networks

  title={Efficient Algorithms for Wavelength Converter Placement in All-optical Networks},
  author={Ling Fei Li and Arun Somani},
In this paper, we consider the optimal converter placement problem for a given number of converters on a path topology in all-optical WDM networks. The placement of converters on a path divides the path into segments. A segment is deened as a set of links between two consecutive converters on a path. We rst introduce and prove that optimal placement considering end-to-end performance is obtained when the segments on a path have equal blocking probability. This result is then used to achieve… CONTINUE READING
