 (Mijumbi, Serrat, Gorricho, Bouten, Turck, & Boutaba 2016). CONCLUSION To remove the network ossification and provide solutions for the changing network needs, the TSP are looking forward to create an environment that will transform the OSS/BSS component of a telecom sector towards virtualized services. Surely NFV will provide the flexibility and ease of deployment with lower Capex and Opex but NFV is in infancy state SO it will take time to be implemented fully. On moving the NF function over the cloud all issues inherit from the cloud computing. The discussed challenges need to tackle SO that it will become standard technology used in the telecom industry.
