Abstract :
The effects of wavelength conversion on wavelength routing optical networks with dynamic non-Poisson traffic are investigated. A model that characterizes any non-Poisson traffic by its first two moments is utilized. The arrival occupancy distribution of busy wavelengths for this model process is derived and is used to analyze the effects of wavelength conversion. The model predicts that traffic peakedness plays an important role in determining the blocking performance.
