In 1992 and 1993, a series of experiments using the NetDyn tool was
run at the University of Maryland to characterize network behavior.
These studies identified multiple design and implementation faults in
the Internet. Since that time, there has been a wide array of changes
to the Internet. During the Spring of 1996, we conducted a
replication of the NetDyn experiments in order to characterize
end-to-end behavior in the current environment. In this paper, we
present and discuss the latest results obtained during this study.
Although the network seems to be stabilizing with respect to transit
times, our current results are similar to the results from past
experiments. That is, networks often exhibit unexpected behavior.
The data suggest that while there has been improvement, there are
still problem areas that need to be addressed.
