End to End Internet Packet Dynamics

This paper reports a large scale study of Internet performance using daemons installed on more than thirty nodes. The study goes on the conclude a list of result about various irregularities seen in Internet routing. It clears some misconceptions and shows that these irregularities do happen and sometimes frequently. Many of these irregularities also happen in site dependent fashion.

While many of these results are interesting facts and potentially lead to other further investigations of Internet irregularities. However, I feel the more valuable lesson from this particular study is the process of evaluating Internet performance at large scale. They were able to obtain a controlled experiment environment by embedding network daemons at various sites. I feel it will be more and more difficult to convince organizations to participate in today's world, especially non-academic settings.

They mentioned that they used 100k data to test bulk transfer. That seems quite low for any network today, and perhaps even low for Internet in 1995.
