In comparison to the state of the art, the consortium was the first to propose and analyze an architecture for slicing across multiple administrative and technological domains. The work conducted here has served as a reference for many other research consortia. In addition, the consortium proposed new design patterns for lightweight control plane functions, new schemes for deep data programmability, new algorithms for the composition of slices and the placement of VNFs, and new solutions to cope with scalability issues in network slicing, leveraging the concept of resource pool and also in-slice management.
The consortium developed a number of orchestrators for the creation of different types of slices, demonstrating the following proofs of concept:
1. Demo for end-to-end orchestration of mobile network slices including RAN slices; featuring RAN slicing and multi-technological domains;
2. Demo for IOT end-to-end network slices orchestration; featuring multi-technological domain orchestration, and IOT-oriented orchestration; and
3. Demo for ICN/CDN end-to-end network slices orchestration; featuring multi-domain orchestration and stitching process.
By the end of the project, the partners have developed the sx following exploitable assets:
• Implementation of the 5G core network to support small messages and data plane diversity led by FOKUS
• Network Service Planner led by Aalto
• Programmable RAN open source OpenAirInterface led by EURECOM and Orange
• Deep data plane programmability system (granular fine grain traffic control) led by NESIC and UT
• Resource Pool for Scalable Orchestration led by HITACHI
• CDN/ICN Slicing as a Service led by Aalto and Waseda
The findings of the project have been so far disseminated through different channels and shared with a wide community of researchers and industrials in the form of scientific publications, demos, keynotes, tutorials, and panels organized at different venues. Contributions to Standards Development Organizations have been also made.
