“…The authors of [8] proposed a meta-MAC algorithm for applying SDN principles to the optical access and mobile backhaul networks, which allow to coordinate the medium access control algorithms of different PON technology and physical layers. [9] presents a control plane architecture for SDN-driven converged metro-access networks. The SDN controller maintains communication with the network orchestrator, and exports an abstracted network view to the controllers.…”

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.

“…In the network test-bed demonstrated in [27] the SDN controller architecture, implemented in Ryu, follows the open network foundation (ONF) architecture using three main interfaces: the application-controller plane interface (A-CPI) between the control plane and the application; the intermediate-controller plane interface (I-CPI) between the network orchestrator (NetO) and the access/core network controllers (NCs); and the device-controller plane interface (D-CPI) between the controllers and the physical devices [30]. The LR-PON protocol is a partial implementation of the XGPON standard, with the major differences being the longer distance and the higher split ratio supported.…”

“…13: an SDN-enabled fast protection mechanism and end-to-end service restoration in case of a primary link failure [31], [32]; and an SDN-enabled dynamic wavelength allocation (DWA) in response to an increased traffic demand [30]. In the fast protection use case the service restoration time is measured at the ONU when a failure event is caused by a cut in the backhaul link between the primary OLT and the AN [33].…”

Abstract-This paper reports on the architectural, protocol, physical layer and integrated testbed demonstrations carried out by the DISCUS FP7 consortium in the area of accessmetro network convergence. Our architecture modelling results show the vast potential for cost and power savings that node consolidation can bring. The architecture however also recognises the limitations of long-reach transmission for low latency 5G services, and proposes how to address such shortcomings in future projects. The testbed results, which have been conducted end-to-end, across access-metro and core, and have targeted all the layers of the network, from the application down to the physical layer, show the practical feasibility of the concepts proposed in the project.Index Terms-access metro, network convergence, fixed mobile convergence, long-reach PON, flat optical core, optical island, 5G architecture, next generation multi wavelength PON.

“…The BER is measured at the OLT in burst mode operation on 2s bursts generated by two different ONUs, with ODN path loss for the two ONUs adjusted to represent worst cast loud and soft adjacent bursts the most challenging situation for the burst-mode receiver, for more detail see [12]. The implemented SDN control plane implemented in Ryu, follows the open network foundation (ONF) architecture using three main interfaces: the application-controller plane interface (A-CPI) between the control plane and the application; the intermediate-controller plane interface (I-CPI) between the network orchestrator (NetO) and the access/core network controllers (NCs); and the device-controller plane interface (D-CPI) between the controllers and the physical devices [14].…”

Abstract-This paper reports on the overall outcome of the FP7 DISCUS project, which aimed at designing end to end architectures, protocols and a physical layer exploiting Long-Reach Passive Optical Network an integrated access and metro network interconnected with a low cost flat optical core network. Our architectural modelling results show that the benefits of node consolidation on the access side extends also to the core part, by enabling a flattening of the backbone network, bringing a substantial reduction in the number of router ports. In addition we report on testbed results demonstrating end-to-end service provisioning across multiple network layers, from application down to physical layer Index Terms-access metro, network convergence, fixed mobile convergence, Long-Reach PON, flat optical core, optical island, 5G architecture, next generation multi wavelength PON.
