“…In this way, authors in [8] propose a SDN-OLT solution in GPONs using virtual switches and the OpenFlow standard in order to emulate a SDN layer in the OLT. In addition, authors in [9] propose to implement virtual switches inside ONUs able to select OFDM channels for TWDM-PONs. Other proposals regarding virtual switches for PONs were proposed in [10] to improve the efficiency and flexibility for data center networks, especially for intradatacenter communications.…”

“…Due to these factors, much attention is being paid to investigate the integration of SDN technologies in PON infrastructures. In this way, many research papers try to emulate an SDN behavior on PON legacy equipment, so that PON devices can become SDNcontrollable devices using SDN protocols [8][9][10][11][12][13][14]. In contrast, other proposals focus on moving certain features of current PON devices to external SDN controllers to achieve a centralized SDN control of the network, for example, bandwidth allocation policies or PON devices registration [15][16][17][18][19][20][21][22][23].…”

An Experimental OpenFlow Proposal over Legacy GPONs to Allow Real-Time Service Reconfiguration Policies

The integration of Software Defined Networking (SDN) technologies in Passive Optical Networks (PONs) would provide great advantages to Internet Service Providers (ISPs) and Network Operators, since they can optimize the network operation and reduce its complexity. However, some tasks regarding online service and network configuration strategies are difficult to move to external SDN-controllers since they are time-critical operations. However, the control of some of these policies by SDN techniques could lead to better network and management configuration in a centralized and automatic way. As a consequence, we propose and experimentally test the integration of an OpenFlow approach over legacy Gigabit Passive Optical Networks (GPONs), which allows moving some global service configuration policies to an external SDN controller implementing an SDN management layer that adjust these strategies according to dynamic Quality of Service (QoS) requirements of services in residential users. The viability and efficiency of our approach are demonstrated using a GPON testbed and proposing a new business scenario for ISPs and Network Operators.

“…This section surveys mechanisms for controlling physical layer aspects of the optical (photonic) communication infrastructure through SDN. Enabling the SDN control down to the photonic level operation of optical communications allows for flexible adaptation of the photonic components supporting optical networking functionalities [33], [205]- [207]. As illustrated in Fig.…”

The emerging Software Defined Networking (SDN) paradigm separates the data plane from the control plane and centralizes network control in an SDN controller. Applications interact with controllers to implement network services, such as network transport with Quality of Service (QoS). SDN facilitates the virtualization of network functions so that multiple virtual networks can operate over a given installed physical network infrastructure. Due to the specific characteristics of optical (photonic) communication components and the high optical transmission capacities, SDN based optical networking poses particular challenges, but holds also great potential. In this article, we comprehensively survey studies that examine the SDN paradigm in optical networks; in brief, we survey the area of Software Defined Optical Networks (SDONs). We mainly organize the SDON studies into studies focused on the infrastructure layer, the control layer, and the application layer. Moreover, we cover SDON studies focused on network virtualization, as well as SDON studies focused on the orchestration of multilayer and multidomain networking. Based on the survey, we identify open challenges for SDONs and outline future directions

“…Similarly, in the SDP and SDO context, advanced photonic subsystems are versatile enough in order to enable reconfigurations of key parameters or features by software [10]. According to the definition by Rouskas et al [61], SDO includes not only programmable but also intelligent and self-aware optical layer devices, i.e., they can sense or measure their own characteristics and performance. In addition to software-defined devices, the next generation software-defined metro and access networks will require low-power or energetically autonomous devices.…”

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.
