    Disaggregated optical technologies have the potential to provide cost-effective and vendor-neutral optical node solutions especially suitable for metro networks. Differently from the conventional proprietary networks, specific design, modelling, control and management operations have to be carefully defined and standardized. This paper first presents the most relevant disaggregated optical ...

    SDN solutions for optical transport networks are often associated to single-vendor optical domains, managed as single entities, in a deployment model that is commonly referred to as fully aggregated. Such controllers do export and expose interfaces for the limited control of abstracted resources and operations via north-bound interface (NBI) to operations/business support systems (OSS/BSS ...

    In this paper, we present Alibaba's practices and views on open and disaggregated optical transport networks, with a focus on metro data center interconnects (DCIs). We first discuss technology developments that have enabled open optical transport networks, followed by a presentation of our open optical network architecture for DCI networks. We then describe an overall data center network ...

    The adoption of open network elements (white boxes), based on different technologies, within the disaggregation network paradigm requires the design/implementation of novel adaptive transceiver architectures. We propose a flexible and programmable multi-rate, multi-format, multi-reach modular sliceable bandwidth/bitrate variable transceiver (S-BVT) architecture composed of bandwidth/bit rate ...

    This paper presents and analyzes how disaggregation models in the wavelength division multiplexing (WDM) transport layer could replace the established aggregated model based on mono-vendor systems. Three optical disaggregation models are presented implying different levels of involvement of the telecom operator in WDM system design, assembly ...

    Filterless optical networks based on broadcast-and-select nodes have been proven to be a cost-effective alternative to active photonic network solutions in core networks. However, due to the emergence of novel metro-based high-bandwidth cloud-based services (e.g., Virtual Reality, 4K Video-on-Demand, etc.), filterless solutions have started to attract research attention also in the metro area ...

    Experimental platforms are essential to demonstrate the potential benefits that Software Defined Networking (SDN) can bring to optical metro and backbone carriers' infrastructure. In this context, the Autonomous Network (AN) project is an SDN-enabled five-node metropolitan optical network test-bed located at CPqD. The AN main objective is to bring novel SDN concepts and capabilities down to ...
