Spreading NFV through the Network: the ETSI NFV Use Cases
Overview of NFV Use Cases
Telecom Italia - All rights reserved
Can be divided in two logical groups
‘Architectural Use Cases’
• Network Functions
Virtualisation IaaS
• Virtual Network Function ‘aaS’
• Virtual Network PaaS
• VNF Forwarding Graphs
‘Service Oriented Use Cases’
• Mobile core network and IMS
• Mobile base stations
• Home environment
• CDNs
• Fixed Access Network
Note: not in this grouping and order in the Use Case Document

Mobile core network and IMS
 Elastic, scalable, more resilient EPC
 Specially suitable for a phased approach
CDNs
 Better adaptability to traffic surges
 New collaborative service models
Home environment
 L2 visibility to the home
network
 Smooth introduction of
residential services
Mobile base stations
• Evolved Cloud-RAN
• Enabler for SON
Fixed access network
 Offload computational intensive
optimization
 Enable on-demand access
services

NFV IaaS
EPBEPA
EPD
EPC
Should permit a Service Provider to fulfill, assure and bill for services delivered
to end users across NFVI’s that are independently administered
EP: End Point

Architectural UC: VNF as a Service
Telecom Italia - All rights reserved
NFV IaaS
VNF
VNF aaS
EPBEPA
NFA NFB
Permit to access VNFs to perform some kind of service chaining with other
generic network functions
EP: End Point

8. Open Networking Summit 2014
Spreading NFV through the Network: the ETSI NFV Use Cases
Architectural UC: Virtual Network Platform as a Service
Telecom Italia - All rights reserved
The VNPaaS provides a larger scale service providing a virtual network rather than
a single virtual network function

9. Open Networking Summit 2014
Spreading NFV through the Network: the ETSI NFV Use Cases
Architectural UC: VNF Forwarding Graphs
Telecom Italia - All rights reserved
Allows composition of VNFs into a Service: a "service chain" is the Network Function
forwarding graph that defines the sequence of NFs that packets traverse
