On the predictability and by-passability of end to end delay

We study the patterns and predictability of Internet
End-to-End service degradations, where a degradation is
a significant deviation of the round trip time between a
client and a server. We use simultaneous RTT measurements collected from several locations to a large representative set of Web sites and study the duration and extent
of degradations. We combine these measurements with
BGP cluster information to learn on the location of the
cause
