The fifth generation wireless network (5G) has already begun its journey but making it a reality comes with several challenges along the way. A huge amount of work is underway from telecom operators for designing new technologies that are going to replace the current one (4G). With the arrival of 5G technology, also a wide range of use cases and business models will be enabled. Therefore, telecom networks need to support much greater throughput, lower latency and provide higher flexibility and scalability. To achieve the 5G target goals, the concept of Network Function Virtualization (NFV) is introduced. NFV gives the opportunity to mobile operators to modernize their networks by creating a programmable platform, capable of being automated and exposed for operators to extract more value.
