NfV (Network Function Virtualization)SP-driven Initiative ETSI architecture
Enablers
• Hypervisor and cloud computing technology
• Improving x86 h/w performance
• Optimised packet processing and coding techniques
• Network industry standardising on Ethernet
• SDN based orchestration
Value Proposition
• Shorter innovation cycle
• Improved service agility
• Match capacity with actual demand
– NB : may reduce CAPEX / OPEX
NfV = Transition of network infrastructure services to run on virtualised compute platforms – typically x86
