Abstract
A method for wavelength division multiplexing (WDM) fiber delay line (FDL) optical buffer routing and scheduling of conflicted variable length data packets through an optical router. The method includes ordering of each conflicted variable length data packet and selecting each of the data packets in turn for routing based on the ordering sequence selected. The sequentially assigned conflicted data packet is assigned a wavelength in the FDL optical buffer from (n) available wavelengths, wherein (n)=&lgr;1, &lgr; , . . . , &lgr;n, &lgr;1, &lgr; , . . . , &lgr;n, . . . . Each data packet is converted to the sequentially assigned wavelength (n) and routed to an optical buffer according to the wavelength assignment. If the wavelength of the FDL optical buffer is fully occupied the data packet is dropped.
