A novel composite-star architecture, nicknamed the Petaweb, has been recently proposed for high capacity optical core networks. Its topologic structure is such that electronic edge nodes are always connected to each other through a single core switch, and that the core switches are disconnected. The aim is to simplify the traffic engineering and the upgradeability of core networks. In its regular form, this architecture suffers from high fiber cost and low utilization. A recent work tackles the… CONTINUE READING
