Abstract
A system implementing an optical steering domain that steers traffic flows through a plurality of processing nodes is described. The system includes a first, second, and third wavelength selective switch (WSS). The first WSS receives the traffic flows, and transmits traffic flows out a plurality of tributary ports toward the processing nodes. The second WSS receives the processed traffic from the processing nodes, and sends it to a third WSS. The third WSS receives the processed traffic from the second WSS, and causes the processed traffic requiring further processing to be transmitted out its third plurality of tributary ports to be looped back toward the plurality of processing nodes, and causes the processed traffic that does not require further processing to be transmitted by a different tributary port of the third WSS that is an exit port leading out of the optical steering domain.
