Dagstuhl Seminar: Global Measurement Framework

December 29th, 2013 Comments off

We participated in a Dagstuhl seminar on Global Measurements Framework from November 17 – 20, 2013. The seminar discussed challenges in running a large-scale measurement platform, its associated privacy issues, with a particular focus on how to make it more useful within the regulators, ISPs, and end-users community. Here is a picture from the event:

IPv6 Traffic Growth Update

June 12th, 2013 Comments off

Here is another update of our IPv6 traffic. Averaged over the last year, the IPv6 traffic is about 5% of the overall Internet traffic we have. This is pretty good given the fact that only some parts of Jacobs’ network currently advertises IPv6. In particular, we have no IPv6 in the student dorms (and the graph clearly suggests that students are a major contributor to our Internet traffic – in particular during finals periods).

Measuring Happy Eyeballs at RIPE 66

May 16th, 2013 Comments off

Vaibhav Bajpai just gave a talk about his work on measuring the effectiveness of happy eyeballs at the RIPE 66 meeting. Watch the video recording of his talk.

Measuring the Effectiveness of Happy Eyeballs from Vaibhav Bajpai on Vimeo.

The IETF has developed solutions that promote a healthy IPv4 and IPv6 co-existence. The happy eyeballs algorithm for instance, provides recommendations to application developers to help prevent bad user experience in situations where IPv6 connectivity is broken. We study the effectiveness of the happy eyeballs algorithm.

RPL MIB Testbed

March 8th, 2013 Comments off

A RPL-MIB implementation, based on <draft-sehgal-roll-rpl-mib-06>, has been completed for the Contiki SNMP agent. An AVR Raven mote has been deployed for testing the MIB and is reachable via the following information:

Hostname: rpl-mib.eecs.jacobs-university.de
Port: 1610

If using the Net-SNMP tools, you can retrieve all the MIB objects by using the following:

$ snmpwalk -v 1 -c public udp6:rpl-mib.eecs.jacobs-university.de:1610 1

The current RPL-MIB implementation is hosted under the Jacobs University private enterprise OID number. As such, in order to render the numeric OIDs you must install the JACOBS-SMI and JACOBS-RPL-MIB modules.

Leone Research Project

November 30th, 2012 Comments off

The Leone project is a 30 months research project, funded by the European Commission with close to 2.8 million Euros. The main goal is to research and develop an innovative network management framework that has two major novelties:

  • It is focused on Quality of Experience: Probes sited alongside end users measure performance and functionality to websites and test servers, both local and distant.
  • It integrates multidimensional information: It combines measurements made by probes in the network of the local Internet service provider, probes in networks of other Internet service providers, control plane information etc.

These two novelties enable network management to focus on improving the user’s experience of the Internet in a world of highly distributed and increasingly meshed applications.  The project partners are:

  1. British Telecom (United Kingdom)
  2. MG-SOFT (Slovenia)
  3. Sam Knows (United Kingdom)
  4. Telecom Italia (Italy)
  5. Aalto University (Finland)
  6. Jacobs University Bremen (Germany)
  7. University Roma Tre (Italy)
  8. University Carlos III (Spain)
  9. University Catholique de Louvain (Belgium)
  10. Martel (Switzerland)

We hope that Leone (the lion) will refrain from eating Flamingo and instead both will become friends and lead to synergies.

Flamingo Research Project

November 23rd, 2012 Comments off

The European project Flamingo (yes, simply a name, not an acronym) just finished its kickoff meeting at the University of Twente. The project partners are:


View Flamingo Consortium in a larger map

  1. University of Twente (Netherlands)
  2. INRIA/LORIA (France)
  3. University of Zurich (Switzerland)
  4. Jacobs University Bremen (Germany)
  5. University of Federal Armed Forces Munich (Germany)
  6. Universitat Politecnica de Catalunya (Spain)
  7. iMinds (Belgium)
  8. University College London (United Kingdom)

The goals of Flamingo are (a) to strongly integrate the research of leading European research groups in the area of network and service management, (b) to strengthen the European and worldwide research in this area, and (c) to bridge the gap between scientific research and industrial application. To achieve these goals, Flamingo performs a broad range of activities, such as to develop open source software, establish joint labs, exchange researchers, jointly supervise Ph.D. students, develop educational and training material, interact with academia and industry, organize event, and strongly contribute to (IETF and IRTF) standardization. Flamingo develops a joint program of research activities to contribute to the development of network management and operation frameworks for the Future Internet. The project will run for 48 months and it will receive about 3 million Euro support from the European Commission.

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.
