In this paper we explore scalable power efficient architectures for optical WAN. The network traffic we assume is 10–100 times larger than what it is today, the rationale being power efficiency will become the paramount obstacle in the next decade when network demands dramatically increases by orders of magnitude. We find using optical by bypass, optical switching at major nodes, WAN topology and...
Present-day networks are being challenged by dramatic increases in bandwidth demand of emerging applications. We will explore a new transport, ??optical flow switching??, that will enable significant growth, power-efficiency and cost-effective scalability of next-generation networks.
