SDN and NFV are two novel paradigms that open the way for a more efficient operation and management of networks, allowing the virtualization and centralization of some functions that are distributed in current network architectures. Optical access networks present several characteristics (tree-like topology, distributed shared access to the upstream channel, partial centralization of the complex operations in the OLT device) that make them appealing for the virtualization of some of their functionalities. We propose a novel EPON architecture where OLTs and ONUs are partially virtualized and migrated to the network core following SDN and NFV paradigms, thus decreasing CAPEX and OPEX, and improving the flexibility and efficiency of network operations.
