  Abstract: The emerging software defined networking (SDN) paradigm separates the data plane from the control plane and centralizes network control in an SDN controller. SDN facilitates the virtualization of network functions so that multiple virtual networks can operate over a given installed physical network. Optical network segments, such as passive optical networks (PONs), have become important for providing network access. In this article, we comprehensively survey studies that examine the concepts of SDN and network virtualization in optical access networks; in brief, we survey the area of software defined optical access networks (SDOANs). We organize the SDOAN studies into architecture and protocol focused studies. We then subclassify the studies according to the network layers. In particular, for protocol-focused studies, we consider subclassifications for the physical layer, medium access control (link) layer, and network layer. In addition, we consider subclassifications for studies focused on quality of service, multilayer (multitechnology) networking, and virtualization. Based on the survey, we identify open challenges for SDOANs and outline future directions.
