“…SDN is now mature for L2/L3 packet switching networks but still at a starting stage for wavelength-switched optical networks, even though some interesting proposals have shown up and been experimentally tested [19,40,41]; it is obvious that many studies and experimental tests will be carried in the field of optical SDN very soon. In fact, optical communications have a fundamental role in this network evolution in all segments of the TLC infrastructure; in the access segment, the use of the FTTB-FTTH technologies will enable huge bandwidths and the possibility to set-up VPNs dedicated to specific services.…”

“…This new global overview will permit operational benefits and more efficient usage of network resources. The SDN is the core of this change [13][14][15][16], and so far, many proposals have been made and first experimental demonstrations carried out [17][18][19], pointing out the benefits given by optical architectures. Currently, one of the main aims of SDNs is the cooperation between the TLC network and DC world, including content delivery network aspects [13].…”

This article reports an overview on the evolution of the optical network scenario taking into account the exponential growth of connected devices, big data, and cloud computing that is driving a concrete transformation impacting the information and communication technology world. This hyper-connected scenario is deeply affecting relationships between individuals, enterprises, citizens, and public administrations, fostering innovative use cases in practically any environment and market, and introducing new opportunities and new challenges. The successful realization of this hyper-connected scenario depends on different elements of the ecosystem. In particular, it builds on connectivity and functionalities allowed by converged next-generation networks and their capacity to support and integrate with the Internet of Things, machine-to-machine, and cloud computing. This article aims at providing some hints of this scenario to contribute to analyze impacts on optical system and network issues and requirements. In particular, the role of the software-defined network is investigated by taking into account all scenarios regarding data centers, cloud computing, and machine-to-machine and trying to illustrate all the advantages that could be introduced by advanced optical communications.Acronyms 3G, 4G, and 5G third-, fourth-, and fifth-generation 3GPP third-generation partnership project API application programming interface CAPEX capital expenditure CRM customer relationship management DC data center FSO free-space optic FTTB fiber-to-the-building FTTH fiber-to-the-home GMPLS generalized multi-protocol label switching

Paradoxically, with an ever-increasing traffic demand, today transport-network operators experience a progressive erosion of their margins. The alarms of change are set, and Software Define Networking (SDN) is coming to the rescue with the promise of reducing Capital expenditures (CapEx) and Operational expenses (OpEx). Driven by economic needs and network innovation facilities, today transport SDN (T-SDN) is a reality. It gained big momentum in the last years, however in the networking industry, the transport network will be perhaps the last segment to embrace SDN, mainly due to the heterogeneous nature and complexity of the optical equipment composing it. This survey guides the reader through a fascinating technological adventure that provides an organic analysis of the T-SDN development and evolution considering contributions from: academic research, standardization bodies, industrial development, open source projects and alliances among them. After creating a comprehensive picture of T-SDN, we provide an analysis of many open issues that are expected to need significant future work, and give our vision in this path towards a fully programmable and dynamic transport network.

“…In the SDWN architecture, a global network controller is responsible for the rate management of each OpenFlow device [ 1 , 2 , 19 , 20 , 21 , 22 , 23 ]. In the separation of the control and data planes, control plane unification is implemented for different kinds of networks, including wired Internet Protocol (IP) networks [ 5 , 6 , 8 , 20 , 23 ], Wavelength-Division Multiplexings (WDMs) [ 24 ], and wireless networks [ 25 , 26 , 27 ]. In recently published works, the AIMD adjustment scheme has been further optimized using Lyapunov–Krasovskii functionals for network congestion control in SDWNs [ 28 , 29 ].…”

This paper proposes a novel WOA-based robust control scheme with two kinds of propagation latencies and external disturbance implemented in Software-Defined Wireless Networks (SDWNs) to maximize overall throughput and enhance the stability of the global network. Firstly, an adjustment model developed using the Additive-Increase Multiplicative-Decrease (AIMD) adjustment scheme with propagation latency in device-to-device paths and a closed-loop congestion control model with propagation latency in device–controller pairs are proposed, and the effect of channel competition from neighboring forwarding devices is analyzed. Subsequently, a robust congestion control model with two kinds of propagation latencies and external disturbance is established. Then, a new WOA-based scheduling strategy that considers each individual whale as a specific scheduling plan to allocate appropriate sending rates at the source side is presented to maximize the global network throughput. Afterward, the sufficient conditions are derived using Lyapunov–Krasovskii functionals and formulated using Linear Matrix Inequalities (LMIs). Finally, a numerical simulation is conducted to verify the effectiveness of this proposed scheme.
