EdgeCast Application Delivery Network (ADN) improves dynamic content performance

EdgeCast Application Delivery Network

EdgeCast Application Delivery Network (ADN) improves web page performance by optimizing TCP/IP network paths & communications to reduce latency and increase speed of non-cacheable content.

Dynamic content cannot be practically/effectively cached because a dynamic asset previously generated by a web application would never be requested again. ADN finds other ways through which to speed up data delivery to clients. ADN is able to drastically reduce the amount of time that it takes to communicate with the origin server by optimizing the network path and through the use of both server efficiency and RFC-compliant protocol optimizations. This allows these dedicated servers to transmit dynamic data at a much faster rate than traditional Internet data routes.


EdgeCast ADN performs better than traditional Internet because
EdgeCast PoPs around the world are connected with each other with best selected routes at multi-hundred Gbps capacities
– TCP/IP connections between EdgeCast edge servers and ADN gateway servers are optimized by techniques such as TCP Fast Start, TCP Packet Sizing, Congestion Avoidance, Connection and Packet Multiplexing, etc.
– The closet EdgeCast ADN gateways will be selected to connect to customer origin to maximize transmission performance between customer origin and EdgeCast ADN
– The closet EdgeCast ADN edge servers, based on BGP Anycast technology, will be selected and connected to client to maximize transmission performance between client and EdgeCast ADN

Therefore by routing traffic through EdgeCast ADN rather than public Internet, customer origin can send dynamic content to client at higher speed!

To demonstrate EdgeCast ADN, I simulate dynamic content by adding the following codes in the .htaccess file under the directory demo.cheungwaikin.com/adn/:
<FilesMatch “.(jpg|jpeg|png|html)$”>
Header set Cache-Control “max-age=0, private, no-cache, no-store”

The original page is http://demo.cheungwaikin.com/adn/adn-a.html
The ADN optimized page is http://adn-demo4.cheungwaikin.com/adn/adn-b.html

Random tests at Webpagetest show the ADN optimized page loads faster than the original page:

We can see the Time to First Byte and Content Download of those objects delivered from EdgeCast ADN – the HTML code and the image edgecast-adn.jpg – are faster than that of the origin page.

Google Analytics Page Timings on 4-Apr-2013:
– Original page: 2.25sec average page load time
– ADN optimized page: 1.79sec average page load time

    Must like Edgecast, Mirror Image, http://www.mirror-image.com also provides high quality content delivery network services.

    I have a managed WordPress hosting company that uses ADN with fire host we provide the fastest hosting for WordPress. Do you mind if I borrow your charts? I promise you I will be more than happy to share with you in the future. DNS wise are you running edge cast?
    I will be running Dyn

      Please feel free to repost it. I’m glad that find it useful.

      I try to use every EdgeCast service on my site demo.cheungwaikin.com. I plan to add one demo about EdgeCast Route managed DNS service in Q2 CY14.

    On my opinion, Edgecast may be fairly called one of the leaders in the industry with its SuperPOPs (points of presence) that are located on five continents. Those SuperPOPs allow the end user to get any website content almost immediately from the location that is the closest to the user. So the user becomes a loyal visitor that means more revenue for the website’s owner.
    And it must be said that the speed of a website affects the position of the website in all search engines. The faster the website is the better search engine rankings it has.
    Of course, there many other cdn networks but Edgecast constantly works to overperform those other networks imroving the services it provides. So the website’s owner may be ensure that his website that is on Edgecast’s servers is fast, secured and optimized.
