NFV Ain’t Cloud Applied to Carriers
The network differs from the computing environment in 2 key factors…
Data plane workloads (which are huge!)
Network requires shape (+ E2E interconnection)
HIGH PRESSURE ON PERFORMANCE
GLOBAL NETWORK VIEW IS REQUIRED FOR MANAGEMENT

…which are big challenges for vanilla cloud computing.
AN ADAPTED VIRTUALISATION ENVIRONMENT IS NEEDED TO OBTAIN CARRIER-CLASS BEHAVIOUR

TRADITIONAL CLOUD NFV
• Cloud Management System acting as VIM § No Enhanced Platform Awareness § Networks based on vSwitch
• VNF and Network Service Descriptors à la cloud
• NFV VIM, platform-aware § CPU & NUMA pinning, PCI passthrough,
hugepages, etc. § Networks based on ToR Openflow switch
• VNF and Network Service descriptors, enhanced with platform-aware fields

OpenMANO: A Dataplane-Ready MANO Stack
• EPA-aware VIM • CPU & NUMA pinning • PCI passthrough, hugepages, etc. • Network infra defined by
Openflow control of external (ToR) switches
• Performance-aware NFVO • VNF and NS descriptors, enhanced
with platform-aware fields • Generic VNFM
• DSL enabled • Under development
