“…routers, switches, and APs from the control plane, whereas GMPLS control plane is used as a control for core optical network. In their work they consider parameter that is number of hops per optical flow versus average end-to-end flow setup time (s) to evaluate the performance of the unified control plane network and concludes that as number of hops per optical flow increases the average end-to-end flow setup time also increases [97] Fig. 15, for multi-domain and multi-transport network based on SDN framework with OpenFlow.…”

The evolution of software defined networking (SDN) has played a significant role in the development of next-generation networks (NGN). SDN as a programmable network having ''service provisioning on the fly'' has induced a keen interest both in academic world and industry. In this article, a comprehensive survey is presented on SDN advancement over conventional network. The paper covers historical evolution in relation to SDN, functional architecture of the SDN and its related technologies, and OpenFlow standards/protocols, including the basic concept of interfacing of OpenFlow with network elements (NEs) such as optical switches. In addition a selective architecture survey has been conducted. Our proposed architecture on software defined heterogeneous network, points towards new technology enabling the opening of new vistas in the domain of network technology, which will facilitate in handling of huge internet traffic and helps infrastructure and service providers to customize their resources dynamically. Besides, current research projects and various activities as being carried out to standardize SDN as NGN by different standard development organizations (SODs) have been duly elaborated to judge how this technology moves towards standardization.Conventional networks implement various dedicated algorithms and set of rules on hardware components like application specific integrated circuits (ASICs) to monitor and control the flow of data in the network, supervising routing paths and responsible for configuring various NEs with each other in the network path [5,6]. When the packets are received by the routing devices, in a conventional network, it employs a set of rules, which are already entrenched in its firmware to detect the routing path for that packets as well as address of the destination device in the network. Generally data packets are handled in similar manner, which may be directed to the same destination and all this occurs in an inexpensive routing device. Moreover, special routing device i.e., Cisco router may have the ability to treat different packets depending on their nature and contents. It allows the administrator to mark out priorities of different flows through customized local router programming. Thus, the queue size in each router can manage packets flow directly. Such a customized local router setup allows the operators to handle traffic more efficiently in terms of congestion and prioritization control. The current network devices have the limitation on network performance due to high network traffic, which hinders the network performance in terms of speed, scalability, security, and reliability. The current network devices lack the dynamism in operation, which is related to different types of packets and their contents. It may be attributed to inability to reprograming of the network operation due to the J Netw Syst Manage (2017) 25:321-374 323 MotivationMotivation for adopting SDN technology as NGN can be visualized from the facts given hereunder:• To accommodate the fast expending traff...

“…The main disadvantages of this proposal are the redefinition of technologyspecific encodings and the lack of support for multilayer resource management (i.e., nesting, a concept at the foundation of GMPLS). Azodolmolky et al [91] and Channegowda et al [88] extend OpenFlow for lambda switching by defining OpenFlow agents for optical nodes, and more specifically reconfigurable optical add-drop multiplexers (ROADMs). This approach has the advantage of using existing optical switches equipped with a GMPLS control plane.…”

| Rigid fixed-grid wavelength division multiplexing (WDM) optical networks can no longer keep up with the emerging bandwidth-hungry and highly dynamic services in an efficient manner. As the available spectrum in optical fibers becomes occupied and is approaching fundamental limits, the research community has focused on seeking more advanced optical transmission and networking solutions that utilize the available bandwidth more effectively. To this end, the flexible/ elastic optical networking paradigm has emerged as a way to offer efficient use of the available optical resources. In this work, we provide a comprehensive view of the different pieces composing the ''flexible networking puzzle'' with special attention given to capturing the occurring interactions between different research fields. Only when these interrelations are clearly defined, an optimal network-wide solution can be offered. Physical layer technological aspects, network optimization for flexible networks, and control plane aspects are examined. Furthermore, future research directions and open issues are discussed.

“…An extension to OpenFlow has been developed to handle circuit switching [138]. Other researchers propose the integration of GMPLS control structures into SDN implementations [139], [140]. There has also been a widespread move to build SDN interfaces into commercial optical circuit switching products, for example, [115]- [117], [141].…”

This paper reviews the current state of the art in reconfigurable network systems, covering hardware reconfiguration and its interplay with software-defined networking (SDN).ABSTRACT | Modern high-speed networks have evolved from relatively static networks to highly adaptive networks facilitating dynamic reconfiguration. This evolution has influenced all levels of network design and management, introducing increased programmability and configuration flexibility. This influence has extended from the lowest level of physical hardware interfaces to the highest level of network management by software. A key representative of this evolution is the emergence of software-defined networking (SDN). In this paper, we review the current state of the art in reconfigurable network systems, covering hardware reconfiguration, SDN, and the interplay between them. We take a top-down approach, starting with a tutorial on software-defined networks. We then continue to discuss programming languages as the linking element between different levels of software and hardware in the network. We review electronic switching systems, highlighting programmability and reconfiguration aspects, and describe the trends in reconfigurable network elements. Finally, we describe the state of the art in the integration of photonic transceiver and switching elements with electronic technologies, and consider the implications for SDN and reconfigurable network systems.
