Realization of network function virtualization in fifth generation networks-Core part of network

Kroz niz mobilnih mreža (1G, 2G, 2.5G, 3G, 3.5G, 4G) od sredine 40-ih pa do danas, došli smo ponovno na jednu novu revolucionarnu prekretnicu zvanu 5G mreža. To je mreža koja sa sobom donosi značajno bolje performanse u odnosu na trenutne kao što su vrijeme odziva od samo 1 ms, a brzina prijenosa podataka do 20 Gbit/s. U provedbi implementacije takve mreže nužno su potrebne nove tehnologije kao što su NFV, SDN i mrežno raslojavanje. To su tehnologije koje nastoje zamijeniti sklopovsku opremu sa programskom potporom koliko je to maksimalno moguće. Pomoću tih tehnologija izvedeni su kako jezgra, tako i RAN dio mreže pete generacije i prema tome mogu se slobodno nazvati „tehnologije budućnosti“.Through a series of mobile networks (1G, 2G, 2.5G, 3G, 3.5G, 4G) since the mid '40s we have come to the present where is new revolutionary turnaround called 5G Network right around the corner. This is a network that brings significantly better performance than current as a response time of just 1 ms and data transfer rate of up to 20 Gbit/s. Implementation of such network requires new technologies such as NFV, SDN and network slicing. These are the technologies which are trying to replace the hardware with software as much as possible. These technologies are used to provide implementation of the core and RAN part of fifth generation network and hence can be freely referred to as "technologies of the future"
