SUMMARY:Is there a case for mobile phone content pre-staging
DESCRIPTION:\n\n\n\nContent caching is a fundamental building block of the
 Internet. Caches are widely deployed at network edges to improve
 performance for end-users\, and to reduce load on web servers and the
 backbone network. Considering mobile 3G/4G networks\, however\, the
 bottleneck is at the access link\, where bandwidth is shared among all
 mobile terminals. Assuch\, per-user capacity cannot grow to cope with the
 traffic demand. Unfortunately\, caching policies would not reduce the load
 on the wireless link which would have to carry multiple copies of the same
 object that is being downloaded by multiple mobile terminals sharing the
 same access link.In this paper we investigate if it is worth to push the
 caching paradigm even farther. We hypothesize a system in which mobile
 terminals implement a local cache\, where popular content can be
 pushed/pre-staged. This exploits the peculiar broadcast capability of the
 wireless channels to replicate content "for free" on all terminals\, saving
 the cost of transmitting multiple copies of those popular objects. Relying
 on a large data set collected from a European mobile carrier\, we analyse
 the content popularity characteristics of mobile traffic\, and quantify the
 benefit that the push-to-mobile system would produce. We found that content
 pre-staging\, by proactively and periodically broadcasting "bundles" of
 popular objects to devices\, allows to both greatly i) improve users'
 performance and ii) reduce up to 20% (40%) the downloaded volume (number of
 requests) in optimistic scenarios with a bundle of 100 MB. However\, some
 technical constraints and content characteristics could question the actual
 gain such system would reach in practice..\n\n\n\n&nbsp\;
