3. Mobile Video Growth is Inevitable
LTE will not solve the growing
congestion crisis
Mobile Operators are taking
action via Video Optimization
solutions towards…
OUT OF CONTROL

4. Your Video Optimization Goals?
Reduce
Traffic Volume
Reduce
buffering
Performance
Differentiation
But, are there other effects?

5. What is the Butterfly Effect in Chaos Theory
In chaos theory,
the butterfly effect is
where a small change
at one place in a
deterministic nonlinear
system can result in
large differences to a
later state.

If the trucks were smaller, it
would be easier to merge in…

How Do Users Perceive Network Quality?
Say they expect sites to
download as quickly on their
mobile devices as they do on
their home computers*
Over
50%
network quality is No.1
when selecting a
service provider **

Speed/Efficiency
=
Time of Page
Load
So, Increasing
the Number
of
Transactions
=
Faster Page
Load and
Happy
Customers
But How Do We Squeeze-in More Transactions?

13. How Does Video Optimization Effect Transactions/sec?

400,000
600,000
800,000
1,000,000
1,200,000
Transactions per Hour with and without Video Optimization
TPH w/o Optimization
TPH with Optimization
13.5% increase
in TPH
Video Optimization Increases Transactions Rate
(Effective mainly on peak/congested hours)

15. Optimize Only When Needed
Available
Bandwidth
Optimization Should be Used Only When Network is Congested
>Required
Bandwidth
= Data Congestion

16. Summary
1
Video and its
Effect on TPS
When the Network
is Congested,
Large Video Files
Clog Up the
Network Reducing
TPS
2
Video
Optimization and
Small Objects
Video Optimization
Compresses
Videos and Frees
Space for the
Shorter
Transactions
(Increasing TPS)
3
Optimize Only
When Needed
Video Optimization
Increases TPS Mainly
on Congested
Networks –
Therefore should be
used in congested
networks
4
Browsing Speed
Requires High TPS
Higher TPS
Contributes to
Browsing Speed
and Contributes to
Overall Improved
QoE
Using Video Optimization affects ALL traffic and improves overall QoE

Optimization?
