The Key NFV Challenges
• Support the performance requirements of dataplane workloads
• Optimization beyond current cloud practices
• Adaptive security policy verification
• Security beyond physical access and links
• Smarter forwarding
• Go beyond the 5-tuple
• Enhanced resiliency by elasticity
• Availability beyond overprovisioned failover
• Network functions become applications and services at the same time
• Support for recursive service and components beyond current overlay techniques
• Find a proper integration of different technologies

Starting with RINA in NFV
• Provide the infrastructural network support for NFV
• Service chains via SFC
• VNF internal connections
• VNF resiliency mechanisms
• Full software-based management and control
• Circumscribe it to NFV PoPs and the provision of IP-based
services
• Facilitate service provisioning and stability
• In a compatible way with current network deployments
• Demonstrating an evolutionary path

 Service chain DAF & DIF, managed by NFVO – One per each VNFFG
 VNF DAF & DIF, managed by VNFM(s) – One per each VNF – IPCPs at the DIF provide pooling
 Transport (and shim) DIFs, managed by the VIM – As required by SC and VNF DIFs

Enabling New Design Patterns
• The MANO DAF
• Supporting recursive aggregation at the orchestration stack
• Consistent policy-based orchestration at all layers
• Through an object-oriented approach
• An adaptive, recursive “control plane”
• Quotes above are essential!
• Simplified deployment
• Beyond current network overlay technologies that require specific cross-layer bindings
• Dynamic updates, migration, scaling…
• Infrastructure network properties such as security, topology verification, allocation, load balancing,
failure protection… are directly enforced by the RINA policies
• Network components become reusable
• New service design patterns become possible, even for the current Internet
