Industry Leadership


• Cloud: an introduction without the hype

• SDN, Network Virtualization, NFV … and cloud

• A shout out for OpenStack Pakistan

Agenda

Cloud(ed) thinking!debunking the myth of “Cloud”


• Excess capacity/Under utilized servers

• Machine & Network virtualization

• Monetization opportunity through renting

How the Cloud Business Model started

SDN, Network Virtualization, and NFV


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?

18

Virtualizing x ↔ SDx


The Network Virtualization (NV) Vision

19


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

20

Cloud and NFVHow are these even related!


3GPP Communication ecosystem


Telecom and Provider Networks

Access network Core DC (Private cloud)

Internet

Classifier

Video acc

VoIP

??Network Service chains

metro Ethernet


• Replace hardware network appliances with software

• Deployable over commodity machines

• Cost savings; no vendor lock-in

ETSI and Network Function Virtualization (NFV)

vCPE Classifier

Video acc

VoIP

??Service chains

Each service network function now a VM or a set of VMs


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


NFV architecture

Data-center/cloud infraCMS (e.g. OpenStack)

PLUMgrid


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 ExperienceEverywhere 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

29

Flexibility to deploy Network functions

close to source, on demand
