All-optical cariable buffer queuing.
Researchers at the University of California, Davis have developed an optical router architecture that takes advantage of two classes of all-optical variable queuing buffer components. This provides an optical router architecture with all-optical variable input-queuing or an output-queuing buffer that may boast the excellent scalability, provide versatile wavelength-aware queuing, buffering, arbitrating and load-balancing functions with the QoS/CoS (Quality of Service/Class of Service) capability for the optical packets in a wavelength-division multiplexing (WDM) communication network. Furthermore, the optical router architecture achieves low packet loss rate and eliminates the head-of-line blocking effect without introducing the internal switch fabric speed-up, which are critical technical difficulties while building a large traditional crossbar-based input/output-buffered electronic router.
