9 Our Proposed Network Architecture Our approach Clean slate proposal for the new generation network Achieve high energy efficient/po ower saving network The Internet t Giant Center Router Application Servers Optical Aggregation Network Users (consumers and business customers) ISP and Contents Provider Users No. 9

10 Our Proposed Network Architecture (Cont.) Giant Center Router is one large power scalable router with an amount of traffic. Optical Aggregation Network consists of multi-stage multiplexer/de-multiplexer. Optical Aggregation Network transferss Users data on optical resource (optical slot /λ)transparently.
