Abstract:

Traffic from wireless and mobile devices is expected to soon exceed
traffic from fixed devices. Understanding the behaviour of users on mobile
devices is thus very important in order to improve the offered services
and the provision of the underlying network. In this talk, I will present
some work on analysis of a large (5TB) data set of traffic traces from a
national cellular network operator, and our initial findings. I will
present some overall statistics of the network usage, and then go into
some more detailed results for one particular application, and study the
characteristics of YouTube user requests in the network.

Our results provide an insight into the way people use YouTube on mobile
devices, and we also show some potential of performance enhancements
possible through caching of video content in the access network.
