Abstract
This paper reports on selected traffic
measurement results from access networks in Sweden
and Spain from the ongoing Celtic TRAMMS project.
We draw conclusions based on our findings and
identify issues that need further analysis. Traffic
measurements in access networks are crucial from
several points of view: Better understanding of traffic
patterns can lead to more efficient network design
which leads to cost savings for the operator and
improved end user services. I.e., popular traffic during
peak hours – typically 16-22 for domestic users in both
Sweden and Spain - can be cached locally to relieve
overall network load. A statistical analysis of Youtube
streaming was used to exemplify this. The vast
majority of the traffic volume on the Internet is video
based and from peer-to-peer applications. This shows
that such applications are superior when it comes to
transferring video files, and it suggests that future
access networks should be symmetrical in order to
properly cope with the traffic patterns of the future.
Geographic locality of end-to-end flows has been
identified for incoming and outgoing traffic in Spain
which could be used to analyze peering between ISP’s.
It was shown that stricter legislation in Sweden
targeting illegal file sharing led to a dramatic decrease
of Bit Torrent traffic. This shows that factors not
controlled by the networking community may
seriously impact traffic patterns and user behaviour
thereby indicating the need for closer collaboration
between researchers and network designers on one
side and politicians and regulators on the other side.
