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

Also, with the architecture of SDONs, several applications, such as data-center service migration [17], spectrum defragmentation [18,19], and advance reservation request provisioning [20], have been studied too.…”

It is known that software-defined elastic optical networks (SD-EONs) are programmable and application-aware. However, due to the centralized network control and management, SD-EONs are vulnerable to the network failures that can affect control plane operations. In this paper, we study the problem of survivable control plane establishment (SCPE), i.e., the controller placement and related communication planning for control service backup and migration to protect the control plane of an SD-EON against single node failures. We first propose a novel mutual backup model to improve the survivability of the control plane with high protection efficiency. An integer linear programming (ILP) model is then formulated to solve the SCPE problem with the objective to minimize both the number of deployed OpenFlow controllers (OF-Cs) and the average control channel latency. We also propose a time-efficient heuristic and use simulations to verify that it can obtain similar solutions to those of the ILP. On top of the theoretical investigation, we design and implement the system to facilitate live control service backup and migration with SCPE in an SD-EON control plane testbed. Experimental results demonstrate that the proposed scheme works efficiently, and compared with that using a single OF-C, our scheme achieves much shorter average provisioning latency in dynamic provisioning.Index Terms-Controller placement; Control plane resiliency; Mutual backup; OpenFlow; Software-defined elastic optical networks (SD-EONs).It is known that by decoupling the control and data planes, software-defined networking (SDN) can make the NC&M in optical networks programmable, adaptive, and application-aware [5]. Specifically, software-defined optical networks (SDONs) can typically be realized by leveraging protocols such as the OpenFlow (OF) [6], the network configuration protocol (NETCONF) with YANG as a data modeling language [7], and the path computation element communication protocol (PCEP) [8]. Here, OF is an open standard protocol that incorporates flow-based switching and centralized controller(s) to facilitate software-defined routing, switching, and network management. Moreover, to support software-defined EONs (SD-EONs), the latest OF specification (version 1.5) [6] has included the extensions for identifying flexible-grid optical flows. Hence, by implementing the OF protocol in the control plane, the network operator can manage the data plane elements (i.e., BV-Ts and BV-WSSs) in an EON intelligently with one or more controllers and realize a SD- EON [5,[9][10][11][12].In the meantime, as an optical fiber can carry over Tb/s traffic, ensuring network survivability is vital in optical networks. Hence, researchers have considered the data plane failures in SD-EONs and proposed a few schemes to improve the data plane resiliency [13][14][15]. Note that in a practical SD-EON, the control plane is definitely not failure-proof without specific considerations on the control plane resiliency. For instance, as it counts on the centralized control...

“…When the world-wide deployment of EONs takes place, multi-domain scenarios have to be incorporated [2]. In addition to enhancing network scalability and extending service reach, multi-domain service provisioning can accommodate the inter-operability issues when network elements from different vendors have to be used, and handle the situation in which optical nodes are geographically distributed and/or operated by different carriers.…”

As multi-domain elastic optical networks (EONs) can enhance network scalability, extend service reach, and accommodate the inter-operability issues, it is very relevant to consider them in practical network operations. In this work, we study the problem of how to achieve energy-aware service provisioning in a multi-domain EON, where the optoelectronic regenerators only exist in border nodes. We consider dynamic lightpath requests and propose two algorithms, i.e., the greedy regenerator allocation (GRA) and the set-cover based regenerator allocation (STC), to realize the joint optimization of routing, modulation and spectrum assignment (RMSA) and regenerator allocation. The algorithms are evaluated with extensive simulations that use multi-domain EONs built with different regenerator placement strategies. The results verify that GRA and STC outperform the existing algorithm for energy-aware multi-domain service provisioning, and STC achieves the best performance in terms of both blocking probability and power efficiency.
