Abstract:	In some developing countries, like Peru, optical transport networks are not widely deployed, mainly because of economical factors and geographical difficulties. Its topology has a fishbone-like structure, and it may not need powerful all-optical multicast nodes in order to attend multicast demands. Also, traffic demands may not occupy all the wavelength capacities, which make traffic grooming a necessary capability for saving bandwidth. In the present work we propose an optical node capable of performing multicast routing tasks at traffic grooming level. The node's architecture has been based on two previous works: the 2-Split-Tap-and-Continue (2-STC) node (a multicast capable node with a simple structure, constrained to binary-splitting, but efficient regarding the use of power levels and the number of elements used), and the Stop-and-Go (S/G) Light Tree node (a multicast grooming capable node that uses a labeling technique based on FSK modulation, allowing multicast requests to be routed at the optical level). In this sense, the proposed node improves the use of the optical power, waste of bandwidth and delay, taking advantage of the physical distribution presented in this particular fishbone-like network. Several simulations have been done and results show these assessments. © 2011 IEEE.
