End-to-End Cognitive Network Slicing and Slice Management Framework in Virtualised Multi-Domain, Multi-Tenant 5G Networks
(6/2017 – 5/2020)
Aim: Τhe provision and operation of QoE-driven end-to-end network slicing across multi-operator domains in 5G networks
OTE participates in the SliceNet European research project (https://slicenet.eu/) aiming at facilitating early and smooth creation, delivery and adoption of 5G services with guaranteed service quality by addressing the demanding requirements of verticals, network operators, service providers and users.
5G use cases are so diverse and challenging that the 5G networks must be customizable for the broad range of individual scenarios. 5G network providers are keen to offer “networks as a service” where logical network slices are created and allocated to use cases flexibly and efficiently in a multi-operator environment. SliceNet will create and demonstrate the tools and mechanisms to achieve this ambition. Specifically, SliceNet will design, prototype and demonstrate an innovative, verticals-oriented, QoE-driven 5G network slicing framework. It will use cognitive network management, control and orchestration techniques for the provision and operation of end-to-end slicing across multi-operator domains in 5G networks. SliceNet supports the unique perspectives and requirements on 5G networks of different players:
- 5G vertical businesses: SliceNet enables the verticals to plug and play their use cases with bespoke control to employ 5G slices in a scalable, cost-efficient way via novel mySlice and Scalable Slicing as a Service functions and a one-stop API.
- 5G service providers and users: SliceNet provides unprecedented guaranteed service quality by agile cognitive QoE-optimisation of service creation and delivery.
- 5G network operators: SliceNet presents an integrated FCAPS (Fault, Configuration, Accounting, Performance, Security) framework for truly end-to-end management, control and orchestration of slices by secured, interoperable, and reliable operations across multi-operator domains.
The integrated SliceNet framework will be demonstrated in three representative vertical use cases: Smart Grid, eHealth and Smart City, to highlight the achievements, innovations, and impacts.
In the context of the project, OTE participates in the SliceNet system definition as well as in the actions for the 5G Integrated Multi-Domain Slicing-Friendly Infrastructure. Furthermore, OTE contributes to the effort for the 5G Multi-Domain Slice Management Plane, and the system integration and demonstration. Additionally, the company contributes to the dissemination and exploitation of the research results to be carried out in cooperation with market participants, end-users, the academic community as well as specialists.
The project is co-funded by the EU through the Horizon 2020 Program within the scope of the 5G-PPP phase 2 framework and is scheduled to run for 2.5 years (6/2016-11/2019). SliceNet is being implemented by 15 partners from 10 countries (Greece, Germany, Portugal, United Kingdom, Italy, Israel, France, Spain, Ireland and Romania).
