“…Optical performance monitoring of signal quality is a key enabler of intelligent optical networks, as it facilitates to suitably allocate and manage the network resource and to cope with signal degradation. The S-BVT is appropriately (re)configured accordingly, for SDN and cognitive networking 10 . The monitoring parameters acquisition can be performed either in the optical domain at the network nodes or in the digital/electrical domain at the edge (destination) node (requiring optical-to-electrical conversion and signal demodulation).…”

This work elaborates on: i) why the sliceable bandwidth variable transceiver (S-BVT) represents a key enabler for nextgeneration optical metro networks; ii) how it should be designed to take benefit of its capabilities and advanced features; and iii) which are the promising technologies to be adopted addressing the most relevant requirements and challenges. Specifically, S-BVT architectures based on multicarrier modulation and flexi-grid technologies, adopting cost-effective optoelectronic front-ends, enable flexible adaptation to dynamic traffic and variable path condition, targeting high capacity and scalability, while saving network resources and costs. Programmability and modularity are envisioned for integration in software-defined optical metro networks.

“…With BER monitoring, a network can learn from its path-level performance for small-margin network operation [16]. Optical performance monitoring techniques could also support cognitive optical networking [17], and benefit cognitive SDN orchestration [18] and on-demand control plane functions [19]. However, all these monitoringsupport network operations focused on some use cases and lacked a general operation framework to expose related monitoring information to SDN applications for better network management and diagnosis.…”

Software-defined networks (SDN) decouple the data plane and control plane and enable network programmability in optical networks with a centralized network controller. The optical network would become more dynamic in network architecture and require frequent network reconfigurations. The dynamic optical networks require all kinds of visibility into application data types, traffic flows and end-to-end connections. Thus, we propose an SDN-based monitoring framework that expands network analytics to a converged packet and optical network. With a designated monitoring hub, monitoring information from multiple layers are collected and processed in a centralized server. Several monitoring technologies are provided as network services with the architecture-on-demand optical node architecture. The developed network applications on top of SDN controller process all the collected monitoring information and enables multilayer network analytics based the SDN-based monitoring framework. We demonstrate the proposed multi-layer network analytics successfully in several use cases. In the demonstrations, the multi-layer network analytics enables QoS recovery to avoid network disruption, optical power equalization at any combining device and network debugging and restoration in optical networks. The developed multilayer network analytics provides powerful tools for network re-planning and optimization dynamically.

“…SDON has been implemented in EON for datacenter service migration [44]. A cognitive SDN orchestration was demonstrated over 400-Gbps OPS and Tbps-class Flexi-WDM networks [45]. The first demonstration of an SDN-enabled control plane has also been presented fully controlling node architecture configuration and bandwidth provisioning, over an SDM network consisting of three AoD nodes linked by two multi-core fibers (MCFs) [46].…”
