Performance◇ Placement and

S LA sensitive workloa ds

◇ Fine -tune H ypervisor, O S a nd other bottlenecks

Scalability◇ VNF placement

And More..◇ High

Infra structure Utiliza tion

◇ Service Function Cha ining (S FC)

◇ O S S / B S S Intera ction

◇ PNFV Integration

The Env ir onment

DPA◇ NFVI Level◇ CPU pinning◇ NUMA◇ DPDK◇ S R -IO V◇ And more…

◇ VIM level◇ Recognizes and

◇ Enables “asking” for the right resources

FOR OPTIMIZED VNF PERFORMANCE, ENVIRONMENT AWARE ORCHESTRATION IS REQUIRED

?

Requir ements on NFV in f r as tr uctur e

◇Some differences to generic IT:• Determinism and performance

• Small packet processing

• Real -time, la tency (< 10μs for CPE a nd a ccess functions), jitter

• A v a i l a b i l i t y ( d e t e c t f a i l e d V M s i n < 1 s a n d a utoresta rt, recover host fa ilures)

• Regulatory, geolocation (incl. geo redundancy)

• Accelerate VM migration in planned ma intena nce

• HW acceleration cards

• A d v a n c e d m a n a g e m e n t ( O S S / B S S )
