Objective: Make X Programmable
thus easily change-able, reconfigurable
Tradeoff: Performance, but worth it
e.g. Radio, Storage, hardware,
NETWORKING
Software defined X

What is virtualization?
taking a physical resource
slice/dice it by using ..... wait for it
Software!
What then is Network Virtualization?

Virtualizing x ↔ SDx

The Network Virtualization (NV) Vision
19

20. Copyright © PLUMgrid, Inc. 2011-2016
Location of VM and communication to network elements
use a SDN/centralized controller to distribute state
Physical network elements will change packet headers
use tunneling to encapsulate VM traffic (NVGRE, VXLAN, STT)
NV Challenges … solved by SDN

• Replace hardware network
appliances with software
• Deployable over commodity
machines
• Cost savings; no vendor lock-in

Legacy Limitation
• Physical install appliance/site
• Inefficient asset utilization
• Development is time
consuming, upgrade difficult
• Limits modularity, vendor
choice
Benefits of NFV
• Flexibility / Extensibility
• High asset utilization
• Continuously deployed /upgraded
• Achieve Modularity
• Opens the competitive ' landscape
• Innovative Ecosystem
The NFV Value proposition

Carrier grade software (99.999% reliable)
use clusters and load balance
How: Network virtualization, with SDN for flexibility
Packet processing at line rates, latency and jitter
high speed packet processing on commodity machines
How: SR-IOV, DPDK, IO Visor
Challenges for NFV

Mobile Broadband Experience
Everywhere with more video, higher
speeds, and wide scale availability
Mass Market Personalized TV
with big data analytics helping to shape the
video experience
Critical M2M Communication
bandwidth and latency demands on the
network
5G Use cases and NFV
