Periodic Reporting for period 2 - 5G-CORAL (5G-CORAL: A 5G Convergent Virtualised Radio Access Network Living at the Edge)
Okres sprawozdawczy: 2018-09-01 do 2019-08-31
During the project, there have been fundamental advances in the development of a Fog based architecture compatible with ETSI MEC, defining its main building blocks and interfaces. This architecture substantially departs from previous work and has been validated, obtaining several figures of merit which prove its validity. The 5G-CORAL architecture's main characteristic is its flexibility, able to adapt from fully centralized scenarios to fully distributed. It is also able to operate under different orchestration platforms such as Kubernetes, OSM or forCes, a fully distributed orchestrator developed in the project.
The 5G-CORAL platform has been validated with real use cases including i) Multi-RAT GW, ii) 360 Video streaming, iii) Edge Robotics, iv) SD-WAN, v) High-Speed trains and vi) Automotive scenario.
