  1. 1. NFV Support in RINA Diego R. López Telefónica I+D @ictpristine
  2. 2. 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 @ictpristine 2
  3. 3. 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 @ictpristine 3

  6. 6. 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 @ictpristine 6
