IM 2015, CNSM 2015, Dagstuhl Seminar 16012

February 7th, 2015 Comments off

Our research group is taking an active leadership role in the organization of some key scientific events this year:

For the IM 2015 demo track, we received a good number of submissions and the demo selection process is well underway. For CNSM 2015, we hope to attract a good number of submission. CNSM is the most selective conference in the field of network and service management research. It is important for every researcher working on topics related to network and service management to present and discuss their work at this key event. The paper submission deadline is April 24th, 2015.

Lessons Learned From Using the RIPE Atlas Platform for Measurement Research

May 16th, 2014 Comments off

Lessons Learned From Using the RIPE Atlas Platform for Measurement Research from Vaibhav Bajpai on Vimeo.

In this talk we share our experiences and lessons learned from using the RIPE Atlas platform for conducting measurement research. We describe how subtle rate limits can affect experiment design. We show how calibration of probes from hardware revision down to the firmware version is useful when analyzing measurement results. We describe the usefulness by showing how different hardware revisions affect measurement results. We show how per-hop aggregation mistakes during data analysis can have impacts on measurement results.

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:

  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.

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.
