Abstract

We investigate statistical properties of the traffic especially for ADSL broadband access platforms, which have been widely deployed in recent years. Measurement traces of aggregated traffic are evaluated on multiple time scales and show an unexpected smooth profile with less relevance of long range correlation than experienced for traffic from Ethernet LANs. A reason for the different characteristics lies in the shift to an increasing population of residential users generating most traffic on IP platforms via ADSL access. In addition, data transfer protocols of peer-to-peer networks strengthen the smoothing effect observed in current IP traffic profiles.
