Abstract :
A reconfigurable-optical add/drop multiplexer (ROADM) provides network flexibility and remote provisioning of end-to-end connection via ASON/GMPLS control, which opens the possibility of dynamic construction of multicast trees in optical layer. In this paper, we discuss multicast capable ROADM based on wavelength-selective switch (WSS) and review its experimental results of feasibility demonstration.
