Analytical Tool to Achieve Wavelength Conversion Performance in No Wavelength Conversion Optical WDM Networks

TLDR
An analytical tool is presented to enhance the blocking performance in the circuit-switched wide-area optical wavelength division multiplexed (WDM) networks with no wavelength conversion at the nodes by using wavelength reassignment techniques in no conversion networks.
Abstract
We present an analytical tool to enhance the blocking performance in the circuit-switched wide-area optical wavelength division multiplexed (WDM) networks with no wavelength conversion at the nodes Given any network of arbitrary topology, the aim is to see if one can achieve the wavelength conversion (optimal) performance by using wavelength reassignment techniques in no conversion networks If there is significant performance deviation, the tool identifies the critical points in the network which prevents the reassignment to totally remove wavelength continuity constraint (wcc) blocking Once the critical points are identified, the tool appropriately modifies the routing such that the wavelength reassignment can achieve the optimal performance
