This paper describes a new architecture for providing a full range of IP services and features in the optical layer. This architecture, called optical flow networking (OFN), uses a new class of device that tightly integrates IP routing and reconfigurable WDM. OFN enables new networking capabilities in four key areas: IP over (lambda) provisioning and routing; flow-based QoS optical packet services; IP/(lambda) traffic engineering and differentiated IP/(lambda) service resiliency. With these capabilities, the OFN IP-optical integrated architecture provides key advantages over the conventional, multi-element overlay approach by enabling intelligent QoS IP/(lambda) networking with overall simplified network operations. Therefore, it is a viable solution for next generation metropolitan IP-based services.
