As regards the Network Functions Virtualization (NFV)(SDN)3 some initiatives were launched, such as the creation of the “TIM Brasil NFV Program” developed through four working groups (established on the basis of the logical domains and competencies of the NFV) which have a mandate to define technical requirements, infrastructural plans, roadmaps of the virtualised network functions, “open lab” specifications and reference architecture compliant with the ETSI standard on NFVs.
