NFV workloads pose challenges for IIAS providers. Learn how hardware performance enhancements (DPA&EPA) by Intel, integrated with virtualization providers, can be an NFV enabler, and how advanced orchestration by TOSCA and Cloudify can put the right VNF on the right hardware and coordinate complex deployments.

- 5. NFV Orchestration Requirements Performance ◇ Placement and configuration ◇ Mixed, Multiple SLA sensitive workloads ◇ Fine-tune Hypervisor, OS and other bottlenecks Scalability ◇ VNF placement vs. VM placement ◇ Dynamic VNF scaling in and out ◇ Maintain Throughput and SLA as VNF scales And More.. ◇ High Infrastructure Utilization ◇ Service Function Chaining (SFC) ◇ OSS/BSS Interaction ◇ PNFV Integration
- 7. DPA ◇ NFVI Level ◇ CPU pinning ◇ NUMA ◇ DPDK ◇ SR-IOV ◇ And more… ◇ VIM level ◇ Recognizes and configures platform and infrastructure ◇ Enables “asking” for the right resources EPA FOR OPTIMIZED VNF PERFORMANCE, ENVIRONMENT AWARE ORCHESTRATION IS REQUIRED ?
- 8. Requirements on NFV infrastructure ◇Some differences to generic IT: • Determinism and performance • Small packet processing • Real-time, latency (<10μs for CPE and access functions), jitter • Availability (detect failed VMs in <1s and autorestart, recover host failures) • Regulatory, geolocation (incl. geo redundancy) • Accelerate VM migration in planned maintenance • HW acceleration cards • Advanced management (OSS/BSS) VM1 VM2 VM3 Orchestration service aware platform aware Hypervisor CPU Chipset Switch Silicon NIC Silicon Linux+Apps EPA for demanding applications recognizes and configures platform/infrastructure

Editor's Notes
- Describe VNF requirements (e.g. needs NUMA pinning) Understand environments capabilities (host X,Y supports NUMA, host X has no capacity, host Y available) Match the requirement and capability -> placing the load optimally
