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型的端到端可切片、可靠和安全的架构，实现高传输/交换容量（光电设备为10 Tb/s，光纤系统为1 Pbt/s）;低功耗/成本（节省25%以上）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）智能、相干的收发器，其利用用于P2P和P2 MP应用的多频带和多光纤技术，基于例如，高速等离子体激元调制器/光电探测器和可编程硅光子集成波导网格; ii）无损耗、节能的透明光子集成光开关，消除了OEO转换，例如，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，实现光信道共存，并研究量子抗干扰技术。（后量子）密码学，开发基于物理不可克隆功能的系统;以及iv）可扩展的AI/ML辅助控制和编排系统，负责自主联网、动态和受约束的服务提供、功能放置和资源分配，利用设备提高可编程性和整体网络软件化。为了实现目标和KPI，ALLEGRO已经定义了一个明确的方法，以雄心勃勃的演示者为结尾。该联盟包括工业界和研究/学术界的良好平衡以及互补领域的专业知识。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.
