EVENTO
Cacheability of YouTube Videos in Cellular Networks
Tipo de evento: Seminário LNCC
Video traffic now represents a growing proportion of the traffic oncellular networks, causing capacity problems for operators and in-creased delays for users. Studies have shown that deploying caches atthe network level reduces the delay for the end-user and the overalltraffic volume for the telecom operator. In this talk, we will presentthe analysis of a large nation-wide dataset of real-life videorequests sent by mo- bile users to a popular video streaming website.This analysis is the first to rely on such a large dataset, and shedslight on the optimal cacheability of video content with cachesdistributed in the cellular network, and how efficient some existingcache replacement algorithms are at reducing the number of requestssent to the video provider. We will show that depending on the cachesize and algorithm parameters, up to 20.33% of the requests can beserved by a local cache.
