Characteristics of Fragmented IP Traffic on Internet Links
This is a revised version from that which appeared at PAM2001, fixing a
pair of typos in the text about prevalence of reverse-order and in-order
series. The table with the same data was correct.
Characteristics of fragmented IP traffic on Internet links

Fragmented IP traffic is a unique component of
the overall mix of traffic on the Internet that has not been well
studied. Many assertions about the nature and extent of fragmented
traffic are based in folklore, rather than measurement and analysis.
In this paper, we examine the behavior of measured fragment
traffic and compare those results with commonly cited beliefs.
We analyze characteristics of fragmented traffic, and examine the causes
of IP packet fragmentation. The effects of NFS, streaming media,
networked video games, and tunneled traffic are quantified, as well as
the prevalence of machines whose improper configurations were causing
excessive amounts of fragmented traffic.
To understand the prevalence, causes, and effects of
fragmented IP traffic, we have collected and analyzed seven multi-day
traces taken from three sources. These sources include a university
commodity access link, a highly aggregated commercial exchange
point, and a local NAP.
