Abstract :
This paper analyzes the optical transport requirements of future metro nodes using the traffic forecasts available today. Architectures and dimensioning of optical metro nodes are proposed to cope with 2018 estimated traffic in a large metro network with 4 million users. The challenge of providing dynamic transport services in a distributed data center scenario is also discussed.
