This document discusses mobile internet optimization as an effective tool for mobile operators. It outlines how mobile internet traffic, especially video, is growing enormously which challenges operators to optimize network expenditure and ensure quality of experience. It describes how mobile internet optimization works through dynamic data reduction, transport protocol optimization, and application protocol optimization to reduce traffic amounts and load times, providing capacity savings and quality gains. Global usage of these solutions among operators and providers is also discussed.

4. OPERATOR’S CHALLENGES
while
Optimizing Network Expenditure
It takes forever to
load this
webpage..
Video is stalling so
many times…
Meeting consumer’s demand
Ensuring Proper QoE

5. HOW TO DEAL WITH THESE CHALLENGES?
Speed throttling
Caching
Mobile Optimization

Dynamic Data Reduction
Traffic amount of ‘a’ minus Traffic amount of ‘b’ = Network capacity savings for operator
Traffic amount indicates volume/data rate
Transport Protocol Optimization Application Protocol Optimization
Time to load ‘a’ minus Time to load ‘b’ = QoE gain for subscriber
Optimization Methods

7. Dynamic Data Reduction
lHigh Detail
Foreground lLow Detail
Background
Minimum bandwidth to smoothly run the video
As available bandwidth drops below that minimum
bandwidth, video compression takes place
accordingly (which again reduces the required
bandwidth below available bandwidth) to ensure
uninterrupted service

8. Transport Protocol Optimization
Ø Transport protocols are responsible for end-to-end delivery service
Ø TCP controls the fundamental rate at which data downloads over the
wireless link
Ø TCP is not able to optimally contend with the characteristics of both the
internet and wireless link at the same time
Ø Optimization platform modifies and tunes TCP transmission parameters
dynamically to perform best over wireless link

10. GLOBAL USAGE : AMONG OPERATORS
Overall gain from the solution highly depends on the traffic characteristics of the operator

11. GLOBAL USAGE: SOLUTION PROVIDERS

Ø Rapid rise of secure/encrypted traffic
(mostly HTTPS) is a major challenge of
this solution as this kind of traffic usually
remain untouched by such platform
Ø Some entities developing optimization
solution for encrypted traffic as well
