IPv6 Traffic is Growing

March 7th, 2012 Comments off

There has been a very positive tendency in the amount of traffic shipped over IPv6. Following the winter break, the amount has increased steadily, and its amount is almost three-fold now, compared to the daily averges of summer 2011. The amount of outgoing IPv6 traffic is still, as expected, very low.

International IPv6 Application Contest 2011

November 1st, 2011 Comments off

Our group applied to participate in the “International IPv6 Application Contest 2011” held by the German IPv6 Council. According to the official page of the Council: “The objectives of this contest are the generation of ideas and applications, which help determine how to introduce IPv6, the Internet of the next generation, on a large scale and use it effectively. The contest also provides an opportunity for the next generation of application developers to gain experience with IPv6.” In accordance with the motto of the contest: “Online on the Road – the new IPv6 Standard as driving forces for mobile communication”, our group submitted a Simple Network Management Protocol (SNMP) implementation for constrained devices, using the 6LoWPAN adaptation layer for IEEE 802.15.4 wireless links. The implementation carries SNMP messages over UDP/IPv6.

The SNMP implementation was wrapped with a number of components to produce a WattsApp telemetry platform. The platform demonstrates remote monitoring of sensor readings. It consists of a hardware interface to read data from S0 metering interfaces that is connected to an exporter running Contiki SNMP. A data collector is collecting meter readings and interfacing to a cloud server. The cloud server provides user authentication (via Facebook) and interfaces with a web front end as well as an Android application. All components of the Contiki SNMP telemetry application communicate via IPv6. The platform allows for easy integration of collected data into Facebook, therefore fostering a discussion on efficient energy usage, saving techniques and spreading the awareness of power consumption by different appliances in everyday life. The platform extends to many other fields of everyday activities like sports, leisure, appliances and utilities monitoring, making monitoring of “things around us” more social.

The implementation was possible due to the efforts of Advanced Distributed Systems Lab students, CNDS group members and several external affiliates.

Please consult the following two brochures for more information about the telemetry platform and the SNMP implementation.

The platform web-site can be found at http://wattsapp.net.

Let’s wait for the results of the selection process in one month! 🙂

IPv6 Update

Almost three months passed since the “World IPv6 Day”, and the amount of IPv6 traffic has been almost steady since its first increase on that day.

(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.

Center of Advanced Systems Engineering

February 19th, 2010 No comments

A research center called the “Center of Advanced Systems Engineering” is being established at Jacobs University. Our group has been leading this effort during 2009, from the proposal writing through the proposal evaluation phase and up to the formulation of business plans. Since the beginning of 2010, we are now in the implementation phase where many organizational details are being worked out. While this all keeps us very busy, we are convinced that the centers will provide great benefits for research and graduate education at Jacobs University.

PhD Defense Ha Manh Tran

Ha Manh Tran submitted his PhD thesis during the summer. Today was the defense of his thesis and as you can witness from the photo, he managed to survive the intense hours of presentation and discussion.

Congratulations!

New Web Pages Online

While we moved to WordPress a while ago, the pages went public just now. One reason is that we are working on major software update of our infrastructure and during the summer break we did not make too much progress. But now we are all back to work…

Enjoy the new pages!

Hello world press, ehem word press!

Welcome to new web pages of the Computer Networks and Distributed Systems research group at Jacobs University, powered by WordPress. While we switched to WordPress in April 2009, we decided to also publish some older posts to make the site more interesting (and to keep some of our history alive).
