Optical Packet Switched (OPS) networks combine the potentials of the high capacity optical technology with the flexibility of packet switching. OPS networks provide the finest granularity and highest multiplexing gain in its segment and can be considered as one of those technologies which have the potential to utilize the high bandwidth available through DWDW. However, optical RAMs are still not successful, wavelength converters are expensive and deflection routing is topology dependent. Hence, high losses due to contention occlude the benefits offered by these networks.
