Netfilter Developer Workshop 2005:
The workshop in 2005 was held in Seville, Spain. More information can be
found at the official web page at http://workshop.netfilter.org
and there is also Eric Leblond's great workshop blog at http://nfws.inl.fr/en/
This year the presentation was focused on the current status of the HiPAC
project and future directions. Soon nf-HiPAC will become a full drop-in replacement
for iptables with all the functionality of iptables, outstanding performance
and with none of the drawbacks and limitation of iptables. nf-HiPAC was widely
accepted as the successor of iptables. The Netfilter core team voted for inclusion
into mainline kernel as soon as possible. Before that, proper versioning has
to be added to the kernel <-> user space communication used in nf-HiPAC.

Netfilter Developer Workshop 2004:
The workshop in 2004 was help in Erlangen, Germany. This year's presentation
gave a short overview of nf-HiPAC and the algorithmic approach again, but
then focused on what had happened since the last year. A large part of the
presentation was about the improved algorithm that had been designed during
the previous year. The different optimization strategies are not included
in the slides of the talk, but instead separate pdf files were used. Unfortunately
it is probably very hard to understand the different optimization approaches
without having attended the presentation and without further explanations.
Sorry. We will add proper documentation about HiPAC at some time in the future.

Netfilter Developer Workshop 2003:
The workshop in 2003 was held in Budapest, Hungary. The HiPAC project presented
its first results. People were really amazed by our presentation and all the
work we had done since the last workshop. Probably nobody expected something
like that. The presentation was quite long (too long, more than two and a
half hours), but everybody was listening attentively until the end. This was
the most detailed presentation we have given so far, so if you want to know
something about the internals of HiPAC, start with this presentation. But
please keep in mind that some of the details are obsolete by now.

Netfilter Developer Workshop 2001:
The workshop in 2001 was held in Enschede, Netherlands. The HiPAC project
did not present anything there yet. But we raised a discussion about the problems
of iptables regarding lookup performance and rule updates. People were quite
interested in solutions to these problems, so we were motivated to continue
our work on the HiPAC project which we had just started.
