nb nb-AWG, and f multx.

1. [request (p, Fq, Fj)] [edge (ui,vj)] [color (c,d)]
2. Then Route p so that it ends up in the cthoutput line of its stage-1 AWGR.
3. Working from the other end, we want the request to end in Fj. There are b fibers demuxing to it. We can see that if the stage-2 LWC routes the wavelength to its dth line of its demuxer, the desired output is obtained.
4. The properties of the coloring inherited from Konig’s theorem guaranteed non-blockiness.
