Cost-efficient Multi-period Optical Network Planning: Alternatives and Analysis

Abstract: One of the main objectives of network operators is to upgrade their core optical networks in order to keep the ever-growing demands. In this talk, we will first introduce the multi-period Routing, Configuration, and Spectrum Assignment (RCSA) algorithm. The RCSA will be then applied to different alternatives that operators may consider to update their network. These alternatives will be compared so that we will conclude with some guidelines for operators.

Digital Twins in Optical Networks: Insights and Applications

Abstract: Optical networks are experiencing profound changes with the adoption of software-defined networking concepts and the application of machine-intelligent algorithms for smart network management and control operations. These new features require a reliable digital representation of the network to exploit its full capabilities, i.e., a  mirror of the actual network or, rather, a network digital twin (NDT). The development of NDTs in optical networks is still in its infancy, and its efficient implementation depends on intense R&D efforts involving industry and academia. There are open issues regarding the interaction with analytic models and telemetry services and its interoperation with other applications. This work discusses the main challenges related to implementing NDTs in optical networks and details an application for ML-based soft failure localization.

Agile Metropolitan Filterless Optical Networking

Abstract: The tremendous traffic growth generated by video, cloud, future 5G and beyond services is compelling network operators to re-think network architectures to ensure flexible and efficient service support. Filterless optical networking based on broadcast-and-select nodes and coherent transceivers is considered as a disruptive approach for delivering network agility in a cost-effective manner. The filterless network concept has been widely studied for terrestrial and submarine applications. In this paper, we explore the suitability of filterless architectures in metropolitan networks through a comparative performance analysis with a conventional metro network based on active switching. The results show that a filterless solution with lower, but adequate, network connectivity can achieve up to 36% lower power consumption and up to 45.4% cost reduction at the expense of a 19% higher spectrum usage, which makes the filterless architecture an attractive alternative for metro network deployments.

Accelerating High-Speed Broadband Services through Wireline Wireless Access

Abstract: Based on a wireline wireless access concept, fixed wireless access (FWA) is one of the fastest growing broadband service offerings in recent years. It provides services to customers by connecting wireless network enabled customer premise equipment to public wireless networks. As the wireless network deployments continue to accelerate, Verizon is now reaching more than 135 million population with 5G Ultra Wideband on RF C-band spectrum, which enables even faster expansion of broadband services through FWA. In this presentation, we will discuss the operator’s overall broadband strategy with a focus on wireline wireless access and a visit to the standardization landscape.
