Mobile Internet Optimization: An effective tool for operators

  1. 1. Azfar Adib Lead Engineer, Grameenphone Ltd. MOBILE INTERNET OPTIMIZATION: AN EFFECTIVE TOOL FOR OPERATORS
  2. 2. CONTENTS Ø CONTINOUS BOOST IN MOBILE INTERNET TRAFFIC Ø OPERATOR’S CHALLENGES Ø HOWTO DEALWITHTHESE CHALLENGES? Ø BASICS: MOBILE INTERNET OPTIMIZATION Ø DYNAMIC DATA REDUCTION Ø TRANSPORT PROTOCOL OPTIMIZATION Ø APPLICATION PROTOCOL OPTIMIZATION Ø GLOBAL USAGE :AMONG OPERATORS Ø GLOBAL USAGE: SOLUTION PROVIDERS Ø Q&A
  3. 3. CONTINOUS BOOST IN MOBILE INTERNET TRAFFIC lEnormous growth of data traffic lVideo traffic is the biggest contributor Source: Ericsson Mobility Report , June 2015
  4. 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 plus
  5. 5. HOW TO DEAL WITH THESE CHALLENGES? Speed throttling Caching Mobile Optimization
  6. 6. BASICS: MOBILE INTERNET OPTIMIZATION Compression & Other functionalities (Same content)b aOriginal content Optimized Content 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. 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. 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
  9. 9. Application Protocol Optimization Macara Dynamic Multipart (MDM) Image Resizing Macara Dynamic InterleavingTM 2 Java Script and CSS Inlining Macara Content Tagging (MCT) Image URL Rewriting
  10. 10. GLOBAL USAGE : AMONG OPERATORS Overall gain from the solution highly depends on the traffic characteristics of the operator
  11. 11. GLOBAL USAGE: SOLUTION PROVIDERS Source: Rankings by ABI Research , February 2013 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 THE CHALLENGE
