NFV evolution towards 5G
The document discusses the evolution of Network Functions Virtualization (NFV) towards 5G technology, highlighting its essential role in building a highly distributed network that supports billions of connected devices and low latency requirements. It outlines key components like NFV infrastructure, management, and orchestration, as well as the significance of network slicing in 5G architecture. Additionally, it emphasizes the need for a flexible, software-defined approach to networking that enhances innovation and efficiency in telecom services.

What is NetworkFunctions Virtualization (NFV)? it is the ability to provide network functions on industry standard platforms Evolution of IT virtualization techniques for core network functions • Use standard servers and storage • Reduced equipment costs • Faster time to market • Resource sharing • Targeted service introduction Implement network functions in SW • It can be moved to, or instantiated in, various locations in the network as required, without the need to install new equipment! Classic network appliance approach Message router CDN Session border controller WAN acceleration DPI Firewall Carrier- grade NAT Tester/QoE monitor SGSN/ GGSN PE router BRAS Radio access network nodes • Fragmented non-commodity hardware • Physical install per appliance per site • Hardware development large barrier to entry for new vendors, constraining innovation and competition Network virtualization approach Standard high-volume Ethernet switches Standard high-volume storage Standard high-volume servers Software vendors Virtual appliances Orchestrated, automatic, and remote install Software Vendors Virtual Appliances

- 15. Network Slicing Management& ETSI NFV Also mentioning 3GPP SA5 study item: “Study on management and orchestration of network slicing for next generation network” (FS-MONETS). The Network Slice Life Cycle Management would typically interact with ETSI NFV MANO for these virtualized network services and functions, as shown in Figure 11, with an open Nsl-Ma interface, with Nsl standing for “network slice.” However, the PNF would be managed outside of MANO, as well as subnetwork parts composed of connection of PNF. This would require the Network Slice Life Cycle Management to also interface with a non-virtualized life cycle management & operation environment, as shown on Figure 11, with an open Nsl-PN interface, with PN standing for “Physical Network.”
