Future Internet services are characterized by global delivery of high-performance network-based applications over a high-capacity dynamic optical network. As these types of applications evolve, it is not feasible or scalable for network operators to setup and configure dedicated network for each Internet application type or category. Therefore, a key challenge for network operators is the deployment of dynamic optical infrastructures at high data rates capable of supporting all application types, each with their own access and network resource usage patterns. This paper aims to propose a novel solution based on Optical Network Virtualization for addressing this challenge of the future Internet. This paper first introduces the concept of optical network virtualization, and its implication on optical network elements and transport technologies. Then, it describes how different transport format and switching technologies can be used for virtualization and what the possible challenges are. Finally, it introduces the possible architectural solutions enabled by optical network virtualization.
