Preface

“What a difference a year makes – 52 little weeks”

This variation of the first line from Dinah Washington’s famous song, whichoriginally reads, “What a difference a day makes - 24 little hours,” brings it tothe point:

According to all experts, the press, and most people’s impression we are todayin a serious economic recession. Less than one year ago, we practically lived onthe “island of the blessed” (namely, at Networking 2008 that was held on theisland of Singapore), or in the famous country where “milk and honey flow” (or“where wine and liquor flow”). This convenient situation has changed abruptlywithin less than 52 weeks. It looks like the same kind of problems has emergedin all areas – and the “Networking” area has, of course, been affected, too.

Looking into the 2009 proceedings, however, you will immediately noticethat the manuscripts are largely unaffected by any aspect of the economic cri-sis (which should be a bit of a consolation). Apparently, research directions aredictated by a process that is all too sluggish in order to be quickly and radicallychanged by a “tsunami.” Likewise, the conference itself was prepared in spite ofsuch a crisis.

Some comments about the conference venue and some statistics appear to bein order:

A. Aachen is the westernmost major city in Germany, located on the borderswith The Netherlands and Belgium. Other names of the town include Aix-la-Chapelle, Aken, Aquisgran, Aquisgrana, Cachy and many more – indicatingits very international atmosphere. Despite its ‘borderline’ location, Aachenis situated in the very center of Western Europe. And more than 1200 yearsago, it was the capital of Charlemagne’s empire that comprised Germany,the Benelux, France, Switzerland and a large part of Italy.

B. Perhaps influenced by this international location, the conference received 232submissions from 47 countries from all continents (except for Antarctica).Only 48 submissions survived the review process (i.e., just 20%) and were ac-cepted as full papers. Another 28 more manuscripts (i.e., 12%) were selectedas work-in-progress papers. This rather low acceptance rate should guar-antee timely and high-quality papers. I would once again like to highlightthe fact that six out of seven continents are represented in the conferenceprogram.

VI Preface

Some words of appreciation:

– To IFIP TC6 (Communication Systems) who entrusted us with the organi-sation of Networking 2009 despite three very strong competitors.

– To the local organisers in Aachen who did an excellent, efficient and time-consuming job despite sometimes having to suffer from the strange and unre-alistic ideas that came spontaneously to the mind of the General Chairmanof the conference.

– To the Chairpersons of the Technical Program Committee, namely (in al-phabetical order): Luigi Fratta, Henning Schulzrinne, and Yutaka Takahashi,who did a fantastic and extremely efficient and constructive job.

– To the keynote speakers (once again in alphabetical order) Paul Francis,Mario Gerla, and Paul Kuhn, for presenting up-to-date information con-cerning today’s most important networking questions.

– To the invaluable work of the TPC members and the other reviewers whodid a perfect serious and (in most cases) timely job under very heavy timepressure.

– To the IFIP TC6 delegates and other experts who were prepared to serve asSession Chairpersons.

– To all the (yet largely unknown) attendees who made the conference possiblein difficult financial times.

– To all those who may have been forgotten in this list but who also deservea “thank you.”
