“…In particular, distribution fiber lengths up to around 70 km can be supported without Forward Error Correction (FEC), whereas distribution fiber lengths above 70 km would require standard FEC. The consolidation of the access and metro network infrastructure [219] achieved through the optimized S-BVT transmissions can significantly reduce the network cost and power consumption.…”

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

“…However, in order to increase the reach, other solutions consider active ODN, e.g., a cabinet with an Ethernet Switch. The so-called Active Optical Networks (AONs) have been also considered as broadband access solutions [3,4].…”

“…This last objective seems realistic to be implemented in dense urban areas where optical distribution networks (ODNs) are available and hence operators expect low required investments and high revenues. Different alternatives have been proposed in literature to upgrade and migrate existing access networks to offer at least 100 Mbps per user: for both passive [2] and active [3,4] access solutions. However, the problem is to find the best access technology able to offer 100 Mbps per household in rural areas: the sparser the area, the higher the cost per user and hence, the lower (if not negative) expected benefits for the operator.…”

The telecom arena has become very competitive in dense urban areas where the number of potential customers as well as the requirement of high bandwidth are very important. Sparse areas, on the contrary, are left outside the broadband roll out due to the scarce expected revenues and high predicted investments. This work aims at comparing different architectures combining different technologies from different aspects such as investments, power consumption and delivered bandwidth. A particular case study of a sparse area in Finland is analyzed in detail.

“…These networks are called Active Optical Network (AON) or Active Ethernet, and Passive Optical Network (PON) as shown in Fig.1 [2]. Active Ethernet or Active Optical Network (AON) is standardized according to IEEE 802.3 standard [8], it is used for broadband services (4/5 G for mobile network -Ultra High definition TV -Video conferencing -.. ) [3,9]. It depends on devices which are electrically powered such as routers and switches to distribute the signal [2,10].…”

“…It depends on devices which are electrically powered such as routers and switches to distribute the signal [2,10]. There is a dedicated Ethernet connection to each user that provide dedicated bandwidth of about 1 Gb/s for each user which is acceptable for the current triple play services (voice -video -data) [2,9,11]. Nowadays it can support applications with bandwidth of 10/40/100 Gb/s to each user and in future it can support 400 Gb/s [8] .There are two types of the AON which are based on active Ethernet switch, Point to point (PtP) and Active Star (AS).…”
