Abstract:
A switching system includes one or more line card for input processing, forwarding, queuing, and scheduling data, the line card having a tunable laser to select a wavelength according to the packets' destination for a given burst of packets, so that the burst is switched to a desired destination and sent all-optically to a connected interface; an all-optical switch fabric coupled to the line card to perform wavelength switching; and a centralized arbitrator that resolves the contention from different input ports.
