Improvement in the performance of optical networks in terms of Quality of Service is achieved using an optical packet switching technique. Slotted optical packet switching mechanism employed in non-uniform traffic pattern is analyzed by using a novel Reservation Bit technique. Minimum packet loss is achieved by employing buffers in contrast to the use of buffer-less slotted optical packet switching in non-uniform traffic pattern. Performance of Reservation Bit algorithm is analyzed for different Service classes and is compared with First-Fit wavelength assignment algorithm. Also, delay rate for different traffic pattern is found and analyzed.
