“…All network control logic (such as for routing, TE, etc.) is implemented as applications on top of such a netOS [88]. In turn, the netOS translates the map manipulations into data-plane rules by programming the data-plane switch flow tables via a switch API (OpenFlow).…”

“…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.

Abstract-The growth of intra data center communications, cloud computing and multimedia content applications force transport network providers to allocate resources faster, smarter and dynamically. Software-defined Networking (SDN), has been proposed to create a unified control plane for transport networks (Transport SDN). This article presents an overview on Transport SDN proposals based on OpenFlow, the de facto SDN protocol. OpenFlow is at the forefront of the Transport SDN models and several testbeds have proved the implementation of a unified control plane for multi-domain and multi-technology optical transport networks. We show how OpenFlow can be enabled in current and future network devices through agents and new hardware respectively. Transport SDN can boost the programmability and scalability of the network, increase the network intelligence and allow for dynamic resource allocation and restoration. The review highlights a rapid development of Transport SDN, which seems to tackle the problems that GMPLS encountered for commercial deployment. Finally a comparison between the main research efforts towards a multi-domain transport SDN is given.

“…Recently, Software-Defined Networking (SDN) and, in particular, the OpenFlow (OF) [7] architecture and its associated protocol have attracted strong interest from both academia and industry, and many studies have extended OpenFlow to control optical networks [8][9][10][11][12][13][14][15][16]. The centralized SDN / OpenFlow-based control plane provides flexibility for the operators to control a network given its open interfaces and the open nature of its source code [17,18].…”

Elastic optical networking (EON), with its flexible use of the optical spectrum, is a promising solution for future metro/core optical networking. For the deployment of EON in a real operational scenario, the dynamic lightpath restoration, driven by an intelligent control plane, is a necessary network function. Dynamic restoration can restore network services automatically, and thus greatly reduce the operational cost, compared with traditional manual or semi-static lightpath restoration strategies enabled by network operators via a network management system. To this end, in this paper, we present OpenFlow-enabled dynamic lightpath restoration in elastic optical networks, detailing the restoration framework and algorithm, the failure isolation mechanism, and the proposed OpenFlow protocol extensions. We quantitatively present the restoration performance via control plane experimental tests on the Global Environment for Network Innovations (GENI) testbed.
