“…Software-Defined Networks (SDN) provide the complete separation of control and data plane (user plane). The separation simplifies the network design and operation because instructions are provided by SDN controllers instead of multiple protocols [11]. If a failure occurs on the control plane connections, there is no problem in the delivery of user data.…”

Globalization and technological advances have made significant changes in city development. To integrate all dimensions of the smart city, communication networks are essential. Smart infrastructure integrates transport, electricity, water distribution, sensing systems, information and communication technologies with communication networks. To make optimal use of all the data available from a range of sensors smart cities need reliable networks. This paper gives an overview of optical technologies for application in smart systems and infrastructures that should handle the capacity of data and smart city applications.

“…A few selected academic research projects on general SDN optical networks, namely projects reported in the journal articles [33], [34] and a few related conference papers, have also been reviewed by Bhaumik et al [32]. In contrast to Bhaumik et al [32], we provide a comprehensive up-to-date review of academic research on SDONs. Whereas Bhaumik et al [32] presented a small sampling of SDON research organized by research projects, we present a comprehensive SDON survey that is organized according to the SDN infrastructure, control, and application layer architecture.…”

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

“…As a consequence, many efforts have been done to include self configuration and self-adaptation capabilities in the network devices [2]- [4]. Besides, the concept of Software Defined Net works (SDN) has been explored as a framework to empower optical networks to present a more dynamic response [5].…”

Several approaches have been proposed in order to solve the adaptive control of optical amplifier operating point problem (ACOP). These approaches aim to adjust the gain of each amplifier in a cascade of amplifiers. Some previous resultsshow that it is possible to decrease the noise added by the amplifiers by using these strategies. However, the configurations found by these approaches may degrade the quality of the transmission due to nonlinear effect, because the amplifiers may operate with a high output power. Therefore, the goal of this work is to analyze the impact of the nonlinear effects in the solutions found by these approaches by evaluating the BER of a system that uses a very sensitive modulation in terms of OSNR (64QAM). We tested LossComp, WAdGC and AsHB approaches in a system with 40 channels, using SOGHz fixed grid and considering high and low system input powers. The results showed that for all analyzed approaches the system quality of transmission is affected by the nonlinear effects, and the effect is worse in those with higher amplifier output powers.
