Passive Optical Network (PON) elements such as Optical Line Terminal (OLT) and Optical Network Units (ONUs) are currently managed by legacy, non-flexible network management systems. Software-Defined Networking (SDN) is a new networking paradigm that improves the operation and management of networks. In this paper, we propose a novel architecture, based on the SDN concept, for Ethernet Passive Optical Networks (EPON) that includes the Service Interoperability (SIEPON) standard. In our proposal the OLT is partially virtualized and some of its functionalities are allocated to the core network management system, while the OLT itself is replaced by an OpenFlow (OF) switch. A new MultiPoint MAC Control sublayer extension based on the OpenFlow protocol is presented. The controller is designed to effectively manage and enhance the resource utilization, flow monitoring, bandwidth assignment, quality-of-service (QoS) guarantees, and energy management of the optical network access. The OpenFlow switch is extended with synchronous ports to keep the time-critical nature of the EPON network. OpenFlow messages are also extended with new functionalities to implement the concept of EPON Service Paths (ESPs). Our simulation-based results demonstrate the effectiveness of the new architecture, while keeping similar or improved performance compared to legacy PONs, in terms of delay and throughput.

Passive optical network (PON) are often managed by non-flexible, proprietary network management systems. Software defined networking (SDN) opens the way for a more efficient operation and management of networks. We describe a new SDN-based architecture for Ethernet passive optical networks (EPON), in which some functions of the optical line terminal (OLT) are virtualized and located in an external controller, while keeping the rest of the passive optical network (PON) functionality around an OpenFlow switch. This opens the way for an improved management of the resource usage, bandwidth allocation, quality-of-service (QoS) monitoring and enforcement, or power consumption management, among other possibilities. In order to maintain the time-sensitive nature of the EPON operations, synchronous ports are added to the switch. OpenFlow messages are extended in order to cope with the PON-related parameters. Results based on simulations demonstrate that our proposal performs similarly or better than legacy architectures, in terms of delay and throughput.

“…A software defined access optical network (SDAON) architecture based on OpenFlow-enabled passive optical network has been proposed also by Yang et al [24] in order to ensure remote unified control and service-aware flow scheduling. Their proposal can enhance the resource utilization and QoS guarantee and reduce the OpEx by remote interaction and operation.…”

Abstract:In recent years, architectures, devices, and components in telecommunication networks have been challenged by evolutionary and revolutionary factors which are drastically changing the traffic features. Most of these changes imply the need for major re-configurability and programmability not only in data-centers and core networks, but also in the metro-access segment. In a wide variety of contexts, this necessity has been addressed by the proposed introduction of the innovative paradigm of software-defined networks (SDNs). Several solutions inspired by the SDN model have been recently proposed also for metro and access networks, where the adoption of a new generation of software-defined reconfigurable integrated photonic devices is highly desirable. In this paper, we review the possible future application scenarios for software-defined metro and access networks and software-defined photonics (SDP), on the base of analytics, statistics, and surveys. This work describes the reasons underpinning the presented radical change of paradigm and summarizes the most significant solutions proposed in literature, with a specific emphasis to physical-layer reconfigurable networks and a focus on both architectures and devices.
