From network virtualisation to 5G slicing

From network virtualization to 5G slicing

Management and orchestration (MANO) required to unlock the full potential of virtualisation

This report provides a benchmark of telcos’ network transformation strategy covering SDN/NFV implementations, network slicing overview and also datacenters evolution.

The idea of the benchmark is to give a global overview of the real involvement of telcos on virtualisation through trials, deployments and launch of commercial services involving SDN/NFV.

Questions to be answered are:

Who are the telcos involved in SDN/NFV?
What are their strategy in implementing virtualisation in their infrastructure?
Where do they start implementing it in their infrastructure?

The report also describes how management and orchestration (MANO) is seen as a major issue slowing down the virtualisation implementation as telcos do not agree with a common framework.
