Frequency Analysis of Protocols

Craig Partridge

In the past three years or so, a few different researchers have begun to use frequency analysis to try to understand features of data networks and their protocols. Their use of frequency techniques has varied widely, and in some cases, we've got evidence that frequency techniques work (in surprising ways)without a strong understanding of why they work.

In this talk I try to survey the work that has been done to date, talk about apparent strengths and weaknesses of the various pieces of work, and talk about the interesting open questions that I believe this work raises.

Dr. Craig Partridge is a Chief Scientist at BBN
Technologies and works in the Internetwork Research
Department. Craig has worked on internetworking problems at BBN for twenty
years. Notable bits of work include designing how Internet email is routed,
working with Phil Karn on TCP round-trip time estimation, and designing and
building the world's fastest router in the mid-1990s. Craig has been an
active member of ACM SIGCOMM and the
IEEE Communications Society and chaired the
National Research Council committee
on how the Internet functioned on September 11, 2001. He has written over
25 journal and conference papers, and wrote the book Gigabit Networking
(Addison-Wesley, 1994). A Fellow of the ACM and the
IEEE, and a graduate of
Woodrow Wilson High School in DC, Craig received
his A.B., M.Sc. and Ph.D. degrees from Harvard
