We are proud to announce the availability of our new PURSUIT prototype under an open source license model. The prototype, called Blackadder, implements a fully DAG-based information-centric service model. It is based on the Click modular router and has been tested under Debian and Ubuntu Linux platforms.

The open source package, available on our new Blackadder webpage includes the source code as well as configuration scripts necessary for you to implement your own information-centric applications.

Any feedback, feature requests or comments in general, please post on our Feature Request page or send a direct email to the team.

The test bed originally built out within the PSIRP project has been revived for purposes of testing and demonstrating PURSUIT technology. Initial installations have been finished with first internal tests performed successfully – a simple video streaming application successfully transfered video content over several native forwarding nodes to a video subscriber.

The test bed tunnels native Ethernet frames via the public Internet, using openVPN between the various sites. Ethernet topologies are currently configured through scripts but graphical configuration is worked on.

We hope to have finalized the test bed setup during April that will allow for demonstration of the main functions of our prototype. We will update you in the News section about this.

This year’s ReArch workshop featured a panel on content-centric research efforts with the attempt to identify commonalities and differences between the various approaches. Being in competition with a Dagstuhl seminar, it was seemingly difficult to get members of various project to attend. But the organisers still managed to get three project involved: PURSUIT and two recently granted NSF FIA (Future Internet Architecture) projects, namely the eXpressive Internet Architecture (XIA) and Nebula.

It was interesting to debate the various propositions and argue about possible differences. It seems that the XIA project is closest to PURSUIT. Its notion of content, service and host identifiers is somewhat different from the single information identifiers in PURSUIT. But given that RIds in PURSUIT can also point to mutable data (although our current node architecture implements immutable data objects only), it is not THAT different, really.

Apart from the direct discussions, a major outcome is the identification that possible collaborations in various areas might be beneficial. We will certainly look into these possible areas.

Introduced Thesis Ideas

PURSUIT is very active in pursuing a variety of interesting research ideas. However, our efforts are limited, which is frustrating since we believe that some of the ideas formulated during our work, but impossible to pursue, are worthwhile being looked at.

So we have decided to share some of our ideas with the wider community in order to stimulate the research in this area beyond our limited efforts. Check out our new page of ideas!

Note that we do not claim any intellectual property or copyright on these ideas. However, we would love to collaborate on the take-up of any of the published ideas. Hence, if you do decide to start some research in some of the suggested areas, please feel free to contact us for exploring a collaboration possibility!

I’m pleased to announce that PURSUIT has established an advisory board with esteemed members of the research community. The objectives of this board is to provide feedback on our work through regular informal contacts and information sharing.

The members of this boards can be found here.

The PURSUIT project builds on the successful foundation of the PSIRP project (another FP7 project that will end by 30.09.2010) in terms of architecture, technologies and implementation as well as test bed.

The PSIRP project has been working towards a demonstration at the ICT 2010 exhibition with a voice, video and web application each to demonstrate features of the new internetworking architecture that this project has been aiming for. Although still in early stages, the newly established test bed between several European sites (Cambridge, Essex, Helsinki, Aachen, Sofia, and Athens) will be shown off during the demonstrations (proper Internet connectivity permitting). You can not only see the demonstration but also get some background information on key technologies, quiz some of the project members and get in touch with others.

So: Please visit the PSIRP demo at ICT 2010

A successful start

The PURSUIT kickoff has been a successful start into the project. Most of the kickoff is over by now although the code camp will continue until mid of tomorrow.

Given that the project is hitting the ground running, an emphasis is given on integrating our new partners successfully into the project. CCTV, Essex University and CERTH have been familiar in one way or another with the work that PURSUIT is based on, namely the PSIRP project. However, the necessary introduction into the main concepts and thrusts of PSIRP has been a good exercise, also for existing project partners.

Much discussion was spent on carving out the work for the first few months. Some of the areas include:

  • State-of-the-art: PSIRP performed a substantial state-of-the-art analysis which now needs revision and extension towards the topics of PURSUIT. The current PSIRP results can be found on the FIpedia site and we expect PURSUIT to utilize and extend this existing material.
  • Tussle identification: A crucial approach for identifying the necessary work for our architecture work is to outline the major tussles that our work intends to address or that our architecture intends to somehow address or change. Hence, work will be conducted in identifying these tussles and develop a methodology to qualitatively and possibly quantitatively evaluate the various tussles. It is our intention todeepen our understanding of function placement within our architecture.
  • Transport and Caching: A major thrust of PURSUIT is the necessary functions for transport and caching within our architecture. A first step is understanding existing work in this area and the relation to our work. This includes, e.g., multicast transport, generic router assisted multicast, CDNs and more.
  • Forwarding and topology: Emphasis is given on the implementation of our architecture over various sub-architectures, specifically optical and wireless. Techniques for topology management and forwarding tree construction in these environments are investigated in our early work with the goal to later implement various design choices.
  • Mobility: How to handle mobility of publishers and subscribers (and even sub-networks) is crucial for understanding the mobility support of our architecture. Focus will be given on properly understanding the existing state-of-the-art in this space, such as the work on seamless mobility in the IETF.
  • Extending the node implementation: Our current Blackhawk code basis provides an early prototype for possible future networking nodes of our architecture. Several activities are planned to extend this basis, e.g., through the integration with Click (see previous post). This aims for simplifying the extension of the platform for, e.g., caching or transport solutions in our future research.

Overall, the project kickoff was an exciting start into the new project with many ideas and concrete areas of work that will continue and expand the foundation that the PSIRP project has provided. You can expect some of the outcomes of the areas above to be visible in the future on this site. There are various other activities, partly related to the areas above, that will be started, too.
