8. • ADN is an accepted industry term for a variety of techniques used to enhance
performance of website & application delivery.
• Focuses on “dynamic” vs static content. Particularly useful for Web 2.0-style applications.
• Can provide similar performance benefits of CDN with or without the caching component.
• Leverages the distributed “edge” to optimize the communication path from the client to the
origin.
• Typically involves various combinations of server and protocol optimizations, and
connection handling to overcome sub-optimal default behavior of traditional devices
& operating systems. Some examples of typical techniques developed and
implemented over many years:
• TCP Fast-start
• TCP packet sizing
• Connection keep-alive
• Connection & packet multiplexing
• Route selection & multi-pathing
• Parallelization
• Resource/DNS prefetching (can also be applied to standard CDN)
• Compression
• Content adaptation/optimization

9. FEO Features Benefits
 Provide intelligent content optimization  Keep application data and logic off
the network altogether
 Dynamic assembly of HTML at the edge
 Reduce the number of request-
 Centralize optimization of static resources response cycles
 Automate application of web optimization best practices  Reduce the size of responses,
downloads, and cached pages
 Enhance control across platforms
 Improve the browser layout of pages
and reduce bounce rates
 Increase revenues
 Increase search engine ranking
 Improve page view metrics and site
stickiness
Page Rendered with Edge Optimizer
 Avoid cost of recoding
 67.7% increase in data delivered in HTML
 36.7% reduction in page load times
 48.1 % improvement in perceived load start
 18.2% increase in open connections
Page Rendered without Edge Optimizer
 28.9% increase in number of hosts
 53.1% reduction in number of objects retrieved
