Optical networks have historically been designed to be operated statically. Connections are overprovisioned so that they remain uninterrupted over several (e.g., 10) years, using high physical-layer margins cover the evolution of physical conditions and modeling uncertainties. As a first step, we can increase efficiency without sacrificing network reliability by removing uncertainties reducing long-term margins, observing adjusting them at intermediate periods. This requires certain...
Considering flexible technologies available nowadays, operating optical networks much closer to their physical capacities is very tempting but necessarily requires efficient network automation. To achieve this, the two main challenges are handling failures, and accurately predicting performance in dynamic environments. We experimentally demonstrate ability of ORCHESTRA solution for early detection localization preventively mitigate impact, thus guarantee smooth operation. Then, leveraging...
Botnets are one of the most powerful cyberthreats affecting continuity and delivery existing network services. Detecting mitigating attacks promoted by botnets become a greater challenge with advent 5G networks, as number connected devices high mobility capabilities, volume exchange data, transmission rates increase significantly. Here, 5G-oriented solution is proposed for proactively detecting in highly dynamic network. subscribers' requires reconfiguration, which handled combining...
Smart building applications require robust security measures to ensure system functionality, privacy, and security. To this end, paper proposes a Federated Learning Intrusion Detection System (FL-IDS) composed of two convolutional neural network (CNN) models detect IoT device attacks simultaneously. Collaborative training across multiple cooperative smart buildings enables model development without direct data sharing, ensuring privacy by design. Furthermore, the design proposed method...
As the fifth generation (5G) mobile communication systems are commercially deployed, they bring new services, enhance user experiences, and offer various opportunities to different industries. Despite its advancements, 5G encounters several challenges. To tackle these issues, global industrial, academic, standards organizations actively researching on sixth (6G) wireless systems. 6G networks envisioned as a transformative shift in interactions between physical, digital, human realms, paving...
To fully cope with the requirements of innovative 5G use cases, evolving business models and flexible networking scenarios spanning multiple administrative domains are envisioned. In this context, transparent trusted frameworks that enable network service providers infrastructure to advertise, negotiate acquire, in real time, resources services, distributed over various geographical areas, extremely valuable. address goal, emerging Distributed Ledger Technologies (DLTs) arise as well-suited...
Optical networks are evolving toward self-adaptation exploiting self-observation of network conditions (e.g., through monitoring at the physical layer). Thus, according to information, reconfiguration devices including switches and transponders transmission parameters) is acted. Typically, thought as centralized, where a central software defined networking (SDN) controller holds overall view topology resources and, upon connection request, it decides for routing spectrum assignment, then,...
This paper presents an orchestration framework for the delivery of 5G vertical services and end-to-end network slices in a multi-domain scenario. The proposed architecture relies on business model where verticals service providers take roles digital consumers, providers, each acting its administrative domain. interactions procedures among these entities leverage standard solutions interfaces information models defined by ETSI 3GPP. also proof-of-concept applications two H2020 European...
We experimentally demonstrated a fully disaggregated white box composed of two different types transponders, monitors (including filtering effect parameters), add-drop multiplexers, and switches. NETCONF YANG control the hardware.
We experimentally demonstrate a self-healing network, following the observe-decide-act paradigm: monitoring reveals degradation, decision is taken, network reconfigured to restore service. also demonstrate, for first time, pre-programmed resilience in integrated data/control testbed.
White boxes, originally introduced in data centers, are expected to soon also penetrate the market of wide area networks, since operators see them as a way drive down capital expenditure. Indeed, white boxes can be composed modules from different vendors, removing traditional vendor lock-in and creating more competition market, thus reducing hardware costs. In this paper, we describe experimental demonstration <italic xmlns:mml="http://www.w3.org/1998/Math/MathML"...
The ever-increasing demands in traffic fueled by bandwidth hungry applications are pushing data centers to their limits challenging the capacity and scalability of currently established transceiver switching technologies center interconnection (DCI) networks. Coherent optics emerged as a promising solution for inter-DCIs offering unprecedented capacities closer relaxing power budget restrictions link. QAMeleon, an EU funded R D project, is developing new generation faster greener sliceable...
Network slicing is an essential 5G innovation whereby the network partitioned into logical segments, so that Communication Service Providers (CSPs) can offer differentiated services for verticals and use cases. In many cases, requirements vary over time CSPs must dynamically adapt slices to satisfy contractual slice QoS, cooperating using each others' resources, e.g. when resources of a single CSP are not sufficient or suitable maintain all it's current SLAs. While this need dynamic...
Operating optical networks much closer to their physical capacity is very tempting but necessarily requires improvement on the way failures are handled. In this paper, we experimentally demonstrate ability of ORCHESTRA solution for early detection and localization failures, proactively mitigate impact thus guarantee smooth operation without traffic interruption.
