In this research a new optical packet switching architecture is proposed and investigated. Output line contention is resolved by optical delay line buffers. By introducing a WDM technology, parallel buffer can be equipped with multiple wavelengths on the optical delay line buffer. An ultrafast optical code label processing technique would be fast enough for packet scheduling that selects the appropriate output port, wavelength, and delay line buffer. To evaluate the switch performance, we model an output port of our switch as a multi-server and multi-queue system where each server corresponds to a wavelength and where each arriving packet joins the shortest queue. The results of the analysis and of simulation experiments show that the use of the WDM technique can greatly improve the switch performance in terms of packet loss probabilities.The optical implementation of routing table lookup which allows to perform the long-prefix match is investigated. The WDM buffering using fiber delay lines is experimentally studied at 40Gb/s.
