The evolution from operating separate IP and optical network layers to operating in an integrated, multi-layer way maximizes the natural synergies between IP routing and optical transport technologies. Nokia and Infinity are uniquely positioned to provide this integrated technology. IP and optical integration enable the combination of state-of-the-art routing and optical transport technologies, providing a more agile, dynamic, and integrated network with significant cost and performance synergies. With the transition to all-IP and cloud-based services, many customers and enterprises are also considering how integrating IP routing and transport may help them reach their business goals.
