• 5GT-MTP handles the cloud and networking

resources for deploying dynamically network

services

• Single platform coordinating multi-domain and

multi-tecnology resources (i.e., cloud, RAN,

packet and optical)

Conclusions

Optical technology is key for the development of 5G fronthaul and backhaul

networks.

SDN Programmability of optical fronthaul/backhaul networks requires common data

models and protocols.

NFV Service platform are not fully integrated with SDN controllers. Need to further

develop a common API.

Network slicing is a key enabler for the verticals, but many projects are proposing

proprietary solutions.

MEC is key for the deployment of connected car, but it has to be integrated with

SDN, NFV and cloud to guarantee end-to-end performance.
