Schneider et al. [7] also study clickstream
data, but their focuses are feature popularity,
session characteristics, and the dynamics within
OSN sessions. The distribution of HTTP
request-response pairs reveal the popularity of
different features. The popularity of features
can be different among users from different
areas and of different OSNs. It can also differ
by the time spent by the users. Besides, the distribution
of transmission bytes per OSN session
is given, which helps the ISPs learn the traffic
pattern of different OSNs. Photo features
account for most traffic bytes of OSNs. It also
shows the duration of sessions and number of
subsessions within a session. Moreover, the article
reveals the dynamics within OSN sessions. It
is found that most users access web sites other
than OSNs during OSN sessions for more than
1 min. That is, users can be inactive when
accessing the OSNs.
