Are CDNs effective for mobile users?

When talking about CDNs (Content Delivery Networks), they are remarkably captivating in minimizing the latency within the broadband systems, though in the mobile systems, same outcomes can’t be achieved. The moment CDNs work outside of mobile, RTT (Round-Trip-Time) is comparatively long from the core of gadget network and then back. The major problem is ‘centralistic’ mobile networks, where all the traffic on mobile is absorbed via core network.

Numerous arrangements are there in order to address the mobile acceleration. Existing acceleration solutions remains in the core network or out of mobile network. The arrangements uses different technologies, for instance, Trans rating in the video optimization, forming and pacing, flow control of TCP, content catching, improvements, and much more.

“In the year 2013, the mobile data across the world raised over 81%, year by year to around 1.5 Exabyte’s each month,” as per the ‘Visual Networking Index’ of Cisco. With the time, when the usage of smartphone increases and similarly the traffic increases, enterprises are required to keep in mind the mobile experience. The CDN Networks (Content Delivery Network) of mobile improves experience via RAN (Radio Access Network) acceleration following the below-mentioned steps –

• Minimizing the data traffic of mobile via text compression
• Minimizing on dynamic video content downloading via video pacing
• Utilizing the TCP acceleration adjusted in order to fit the client’s mobile systems.

Usually, latency ranges in between 75 to 140ms; though, it might be higher especially for the mobile clients reaching the website on 3G network. It can indicate with not much stretch like within 2-3 sec loading time that is a big deal if it is considered one of the numerous factors which can slow down the speed of pages.
