“…For example, dynamic spectrum management can minimize the interferences among very high-speed digital subscriber lines (VDSLs) in fiber to the cabinet (FTTC) architecture, with further improvements in addition to the benefits of vectoring techniques [19]. Different classes of service and end-to-end traffic engineering can be actuated in order to guarantee pre-determined round-trip delay for mission-critical applications requiring high interactivity [10].…”

“…Most of the subject involved in the consultation (52% of the answerers) agree that the on-going virtualization of network infrastructures will have an impact on the future demand for wholesale access products, but not in the short term (more than 10 years needed according to the 55% of the answerers), as shown in Figure 4. among very high-speed digital subscriber lines (VDSLs) in fiber to the cabinet (FTTC) architecture, with further improvements in addition to the benefits of vectoring techniques [19]. Different classes of service and end-to-end traffic engineering can be actuated in order to guarantee pre-determined round-trip delay for mission-critical applications requiring high interactivity [10].…”

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.

“…Currently, numerous studies related to "virtual" or "software-defined" PON and OLT are under way (e.g. CORD [2], SDAN [3] and a recent review [4]). However, most existing studies assume the dedicated hardware-based virtual OLT.…”

Implementation of software-based EPON-OLT and performance evaluation

In order to meet the diversifying demands, we propose the architecture of the software-based virtual EPON-OLT, where all of OLT functions except PHY-Layer are implemented as software running on an x86 server. The EPON-OLT requires not only high throughput, low latency but also accurate controls for the upstream transmission timing of ONUs. In order to satisfy these conditions, we introduced two methods for the virtual OLT: (1) Separation of D-Plane/C-Plane and (2)
