Agile uLtra Low EnerGy secuRe netwOrks (ALLEGRO)

ALLEGRO旨在为下一代光网络设计和验证一种新颖的端到端可切片、可靠和安全的架构，实现高传输/交换容量——光电设备10tb /s，光纤系统1pbt /s。低功耗/成本-节省约25% -安全的基础设施和数据传输。该架构依赖于关键的使能创新：i)基于高速等离子调制器/光电探测器和可编程硅光子集成波导网格，为P2P和P2P应用开发多频带和多光纤技术的智能相干收发器；ii)无损、节能的透明光子集成光开关，消除了OEO转换，例如，在数据通信应用中使用o波段的片上放大；iii)在功能/协议架构和通信方面，采用一致的安全方法，进一步改进QKD系统，实现光通道共存，研究抗量子（后量子）加密，开发基于物理不可克隆功能的系统；iv)可扩展的AI/ML辅助控制和编排系统，负责自主网络，动态和受限服务供应，功能放置和资源分配，利用设备增加可编程性和整体网络软件化。为了实现目标目标和关键绩效指标，ALLEGRO已经定义了一个明确的方法，以雄心勃勃的示威者结束。该联盟包括工业界和具有互补领域专业知识的研究/学术界的良好平衡。ALLEGRO的结果将在主要会议、活动和高影响力期刊上传播。它们将产生具体和可衡量的经济和社会影响，有助于实现欧洲的关键目标，加强欧洲在正在进行的数字化和绿色转型中的领导地位和数字主权。

ALLEGRO aims at designing and validating a novel end-to-end sliceable, reliable, and secure architecture for next-generation optical networks, achieving high transmission/switching capacity -- with 10 Tb/s for optoelectronic devices and 1 Pbt/s for optical fiber systems --; low power consumption/cost -- with > 25% savings -- and secure infrastructures and data transfers. The architecture relies on key enabling innovations: i) smart, coherent transceivers exploiting multi-band & multi-fiber technologies for P2P and P2MP applications, based on e.g., high-speed plasmonic modulators/photodetectors and programmable silicon photonic integrated waveguide meshes; ii) loss-less, energy-efficient transparent photonic integrated optical switches, eliminating OEO conversions, e.g., with on-chip amplification in the O-band for datacom applications; iii) a consistent approach to security, in terms of functional/protocol architectures and communications, further improving QKD systems, enabling optical channel co-existence and researching on quantum-resistant (post quantum) cryptography, developing systems based on physically unclonable functions; and iv) a scalable AI/ML assisted control and orchestration system, responsible for autonomous networking, dynamic and constrained service provisioning, function placement and resource allocation, leveraging devices increasing programmability and overall network softwarization. To achieve the target objectives and KPIs, ALLEGRO has defined a clear methodology ending in ambitious demonstrators. The consortium includes a good balance of industry and research/academia with know-how in complementary fields. The results of ALLEGRO will be disseminated in leading conferences, events, and high-impact journals. They will have a concrete and measurable economic and social impact, contributing towards achieving key European objectives, reinforcing European leadership and digital sovereignty in the ongoing digital and green transitionno project summary.
