Impairment Constrained Based Routing for Managed Reach WDM Optical Networks

  title={Impairment Constrained Based Routing for Managed Reach WDM Optical Networks},
  author={Dimitrios Vogiatzis and Carmen Mas Machuca and Ioannis Tomkos},
Managed reach networks are networks that allow placing of regenerators in the main cities and at requested distances. These networks minimize the number of regenerators but need a routing approach able to establish the connections through regenerating nodes when the signal quality deteriorates. For this purpose, Impairment Constrained Based Routing (ICBR) is used. Considering that impairment related information is exchanged through signaling, the ICBR should be able to compute paths that… CONTINUE READING
