Conference Minutes

Conference: Informatik 2004
Workshop: Algorithms and Protocols for Efficient Peer-to-Peer Applications
Talk: Managing Internet platforms wit predominant P2P traffic
Presenter: Gerhard HaÃ?linger, Deutsche Telekom, T-Systems, Darmstadt/Germany

– 50-80% of traffic is caused by peer-to-peer data exchange, 5-20% account to HTTP access (peek values occure during day, low values during night).
– On Slyck, statistics about file-sharing protocols in use can be found.
– eDonkey protocol is dominating in Germany (>80%), U.S.: FastTrack (>70%)
– Caches for P2P traffic are problematic due to techical reasons, but also due to copyright problems with data in the cache. A participant pointed out that actually every cachy can potentially contain illegal data, it’s just that concerning p2p, the assumption is always that it transfers illegal data per se.
– Portions of P2P traffic in the access regions are larger then in the backbones and even smaller on international links
– P2P traffic characteristics over time is favourable for ISPs due to the smoothing effect on the daily traffic profile (e.g. video transfer of several Gbyte may last for days). But those characteristics make the increase in traffic volumen hardly predictable with high risk for planning & extension process in internet provider networks

Wanted: Experts for "Open Innovation" Discussion Panel

Sandro Groganz Leave a comment

For OSCOM 4, I am organizing the discussion panel “Open Innovation” which takes place Sept 30, 16:00 – 17:45 (more information below). If you feel like you could contribute to the discussion as an expert, please write to me in private and let me know your field of expertise. Actually, everyone is an expert on something – so please do not hesitate to contact me!

The discussion will be a kind of brainstorming session that could well end in chaos or deep enlightement – depending on the moderator (me) and the attendees. If you come as an expert, I might ask you some specific questions on your field of knowledge and the other participants might do the same as well. Experts do not need to prepare any presentation, just be there, have an open mind and enjoy the experiment.

So, let me know: sandro dot zic at zzoss dot com

Cheers!
Sandro

Discussion Panel
Open Innovation: Learning from Open Source

The fundamental strength of the Free/Libre and Open Source Software (FLOSS) community is how it allows collections of very different groups and individuals to cooperate, develop, innovate and share.

This discussion panel seeks to bring together the forward thinkers attending OSCOM to discuss the specific characteristics of innovation in the FLOSS community and how they could be adopted by business leaders, educators, scientists and politicians.

The panel will discuss:
* the cultural norms, economic factors and technical mechanisms that the FLOSS community relies on
* the broad cultural norms and economic dynamics of various major non-FLOSS communities
* how and why these norms and mechanism are different
* where and how the strength of the FLOSS movement can be shared with other cultures and organizations, from companies and universities to activist groups and non-profit organizations.

Informatik 2004 & KI 2004

Sandro Groganz Leave a comment

Now that summer’s over, the second half of this year’s conference season starts. For me, conference hopping resumes in Ulm/Germany, which is just around the corner of my new home town Biberach. Actually, it’s two conferences in one from September 20-24: Informatik 2004 and the other on artificial intelligence.

I will definitely attend the following two workshops (because I am interested in the topic, but as well because I help out the organisers):

Algorithms and Protocols for Efficient Peer-to-Peer Applications

Open Source Software in an Industrial Environment

Haven’t decided yet which other sessions to attend, there are just too many interesting things going on…

Thanks to Alexander Kaiser who made me aware of this fantastic event and who helped me get the ticket 😉

Session at PHP Conference: Build and Installation Tools

Sandro Groganz Leave a comment

With the advent of PHP 5 and the push to the enterprise market, professional build and installation environments for PHP applications become more and more important. My session at this year’s International PHP Conference discusses pros and cons of such a build system and compares existing solutions like PEAR Installer, Phing, ZZ/OSS Installer. Furthermore, I will take a look at the Java world and identify missing tools that would be nice to have in the PHP world.

A Good Day at LOTS

Sandro Groganz Leave a comment

LOTS is over. This very first event on Open Source in Switzerland was interesting, well organised, and the atmosphere simmilar to Linuxtag.

I was most impressed by the talk of Wolfgang Maass on the potentials of Open Source for the enterprise market. He presented some conclusions from a research analysing the oppinions of several CIOs. Most astonishing, he said that licensing is not really an cost issue for CIOs, they are rather concerned with being independent from a unique vendor. I am looking forward to find his slides on the LOTS Website.

Some pictures are available online in the LOTS 2004 Album. On the LOTS Website, there are some more pictures. Chregu also has a brief report on LOTS.
