In today’s complex networking environments, efficient end-to-end service delivery demands multisegment and multidomain orchestration. Within the ALLEGRO project, we are pioneering a comprehensive framework to manage intent-based requests across multiple domains—ensuring scalable, automated, and intelligent service provisioning.
🔁 What Makes It Innovative?
✔️ Segmented Orchestration: Each domain controller is orchestrated independently while maintaining global alignment.
✔️ Multilevel Topology Database: Offers a unified, global view of the network—essential for seamless navigation and service continuity across domains.
✔️ Inventory-Aware Orchestration: Tracks and utilizes both hardware and logical inventories in every domain for optimized resource management.
🧠 Enter the High-Level Resource Allocation Tool (HRAT):
This advanced scheduling engine calculates efficient paths, optimizes resource allocation, and ensures low-latency, high-performance service delivery across domains.
📡 Standardized & Interoperable Interfaces:
- 🧩 3GPP TS28.541 – for standardized intent request handling
- 🧠 IETF Topology + TE Extensions – for enhanced topology visualization
- 💡 TAPI – for optical control and abstraction
- 🔗 L2/L3 SM/NM Interfaces – for seamless IP layer orchestration
- 📊 IETF-based Inventories – ensuring accurate resource discovery and utilization
💡 The result: A dynamic, agile orchestration framework that enables operators to manage multi-domain networks with precision, scalability, and automation—key to the future of software-defined, intent-driven infrastructures.
