AGAVE (A liGhtweight Approach for Viable End-to-end IP-based QoS Services) is developing solutions for open end-to-end service provisioning based on the notion of Network Planes that may be interconnected across multiple providers to create Parallel Internets tailored to service requirements. The project is investigating a range of Traffic Engineering techniques to realise Network Planes. A lightweight QoS approach is being developed, based on the principles of differentiated routing with inherent load balancing and resilience, without requiring universal deployment of differentiated forwarding.
