Agile uLtra Low EnerGy secuRe netwOrks (ALLEGRO)

Allegro的目标是为下一代光网络设计和验证一种新颖的端到端可分片、可靠和安全的体系结构，实现高传输/交换容量--光电设备为10TB/S，光纤系统为1PBT/S--低功耗/成本--节省25%--以及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)基于例如高速等离子体调制器/光电探测器和可编程硅光子集成波导网，利用用于P2P和P2MP应用的多频段和多光纤技术的智能、相干收发机；ii)无损、高能效的透明光子集成光开关，消除了OEO转换，例如，具有用于数据通信应用的O波段的片上放大；Iii)在功能/协议架构和通信方面采取一致的安全方法，进一步改进QKD系统，实现光通道共存和研究量子抵抗(后量子)密码学，开发基于物理上不可克隆的功能的系统；以及iv)可扩展的AI/ML辅助控制和协调系统，负责自主联网、动态和受限的服务提供、功能布局和资源分配，利用设备提高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，快板制定了一套明确的方法，以雄心勃勃的示威者结束。该联盟包括在互补领域拥有专门知识的产业界和研究界/学术界的良好平衡。快板的结果将在领先的会议、活动和影响较大的期刊上传播。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和绿色过渡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.
