IPv6 Traffic Growth Update

September 27th, 2012 Comments off

Our IPv6 traffic keeps growing, reaching new records since the students are back on campus. Even our outgoing traffic is on the rise. Perhaps Jacobs should go ahead and start making their core services (e.g., the official Jacobs web pages) IPv6 ready as well.

CNDS Web Pages 2.0

July 9th, 2012 Comments off

We are in the process of updating our web pages. We aim at making things more consistent and useful for us and the outside world. One of the new features we added is our new calendar, which can be easily imported into other calendar software. We hope this will make it easier to follow events and deadlines. In order to highlight our activities to improve our pages, we switched to a new theme – wordpress makes all of this remarkably easy.

(Word) Cloud Computing

This image shows how the CNDS web pages look like when the content is rendered as a word cloud. This form of “cloud computing” seems to be visually most attractive and it is quite some fun as well.

We used http://wordcloud.pagemon.net/ to generate the word cloud image. You can try this online tool easily yourself on other web sites of your personal interest. We found this tool entertaining for a while.

World IPv6 Day @ Jacobs University

June 9th, 2011 Comments off

Graph showing the IPv6 traffic at Jacobs University during the World IPv6 DayYesterday, on June 8th, we enjoyed the World IPv6 Day. Here is how the IPv6 traffic changed during the day (measured on the tunnel connecting Jacobs’ IPv6 network to the German research network). Apparently, some very popular web sites like Google and Facebook turned off IPv6 right after the day again. This is probably not so good news…

For comparison purposes, here is a plot showing all traffic (IPv4 and IPv6)  going in and out of Jacobs University around the World IPv6 Day. This plot seems to indicate that we carried a significant portion of our traffic over IPv6 during the World IPv6 Day. Note that the event took place when most of our undergraduate students had already left our campus.

The plot on the right shows the longer term impact of the IPv6 day. While some  sites apparently turned off IPv6 support once the event was over, there is also good news since our IPv6 traffic remains at significantly higher levels. Obviously some sites used by our users left IPv6 turned on. We will try to keep an eye on this to see whether this is stable over longer terms or increases or decreases over time.

Netconf Light Demo at IETF 80

March 31st, 2011 Comments off

Some of us attended the 80th IETF meeting in Prague and we used the opportunity to demonstrate the NETCONF protocol running on AVR Raven motes (so called class 1 devices). Of course, these devices only support a subset of NETCONF, which we call NETCONF Light. Our goal was to prove that it is possible to implement a workable subset of NETCONF even on very resource constrained devices. On more powerful motes, such as Econotag motes, it should be possible to run an almost complete NETCONF stack.

PhD Defense Iyad Tumar

Iyad Tumar submitted his PhD thesis a few weeks ago and today was the day of the defense of his thesis. Iyad managed to survive the intense hours of presentation and discussion. It seems the summer is a good period for getting a PhD degree at Jacobs.

Congratulations!

AIMS 2010 Best Paper Award

Nikolay Melnikov presented a paper co-authored by Kaloyan Kanev discussing an implementation of our stream-based IP flow record query language. The paper received the AIMS 2010 best paper award.

IEEE Oceans 2010 Climate Change Poster

Anuj Sehgal presented a poster discussing the effects of climate change and anthropogenic ocean acidification on underwater acoustic communications at IEEE Oceans in Sydney and his poster did win the second position in the student poster competition.

Running Vegesack

This Saturday, the running enthusiasts of the Computer Networks and Distributed Systems group did join the first  running competition in 2010, the Vegesacker Citylauf. Our goal was to find out where we stand after the long winter and how we cope with a slightly more challenging trail (four times uphill and downhill). Overall we did pretty well, several minutes of improvement for some of us on the 10km distance!
