Performance of an optical packet switch with fixed wavelength converter arrays under bursty traffic

This paper focuses on the performance of a synchronous time-slotted optical packet switch. An optical packet switch with fixed wavelength converter arrays is proposed. The proposed node architecture uses shared fixed wavelength converter arrays and recirculation fiber delay lines to resolve optical packet collisions. To make full use of the fixed wavelength converter arrays and fiber delay lines, two control schemes are presented and studied. The packet loss probabilities of the proposed node architecture are evaluated in detail by simulation experiments. (C) 2009 Optical Society of America
