Periodic Reporting for period 3 - 5GPagoda (A network slice for every service)
Reporting period: 2018-07-01 to 2019-06-30
In the second year of the project, the consortium has focused its efforts on devising new designs for lightweight control plane functions, new schemes for deep data programmability, new algorithms for the composition of slices and the placement of VNFs. The consortium has also looked into the scalability issues relevant to slicing and proposed new solutions, leveraging the resource pool concept and incorporating the in-slice management approach.
The third year of the project (as well as the second half of the second year) was mainly characterized by the efforts of the consortium partners in enabling different test beds that lead to the creation of different slices for different service types (e.g. IoT service, video conferencing services, and on-demand video streaming services). This goes very well inline with the slogan of the proposal, namely a slice for every service. These testbeds are described in details in WP5 deliverables. Their supporting algorithms and mechanisms are detailed in WP3 and WP4 deliverables.
Several dissemination and standardization activities have been also carried out to promote the finding of 5G!Pagoda. The research work conducted by the 5G!Pagoda is followed by a growing community of researchers and industrials in Europe, Japan and many other parts of the world. Some of the 5G!Pagdoa approaches with regard to multi-domain slicing have been adopted by other research consortia and an important impact on the scientific community is expected.
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.
