Agenda
1. What is NFV?2. Why are telcos investing in NFV?3. Open source
for NFV4. Filling the gaps
1. What is NFV?
What is NFV?
Wikipedia:http://en.wikipedia.org/wiki/Network_Functions_Virtualization
NFV is a network architecture concept that proposes using IT
virtualization related technologies to virtualize entire classes of
network node functions into building blocks that may be connected,
or chained, together to create communication services
What is NFV, in simple terms?
Telcos are replacing specialized hardware with VMs running on
commodity hardware
2. Why do telcos care?
Telco services - access
Dial-up
ISDN
ADSL
Cable
Fibre optic
3G/4G
Satellite
Telco services - applications
Voice
Internet/data
Live TV/streaming
VOD
DVR
TV Guide
SMS/MMS
Games
VoIP
Voicemail
Premium services
...
Telcos provide more services todaythan ever before
Telco industry more competitive than ever
Costs dominated by data usage
Customers expect more data for less
Demand for new services increasing
The promise of NFV
Increased agility
Reduced CapEx, OpEx
What is a network node function?
Network functions
Middleboxes
Act on data going through the network
Examples: Load balancer, gateway, IDS, VPN endpoint, NAT,
firewall
Not just telco
3. Open Source and NFV
Why Open Source?
Cloud
Private cloud
DevOps and agile development
Open source drives the cloud
