Research

As you might expect, I do maintain a list of my publications, which also includes publications outside of projects.

Operating Systems

• Memory Optimizations. (2000-)
  Optimizations of virtual memory performance when memory is tight or large data sets are used. Resulted in additional functionality in GNU malloc and speed improvements for GNU awk.
• Crossbow. (1996-1999)
  Toolkit for Integrated Services over Cell Switched IPv6.
• ENskip. (1996)
  Free implementation of the IPsec-based SKIP protocol for several OS platforms. As ISAKMP/Oaklay (later IKE) was chosen to prevail as the key management for IPsec, the source has not been maintained. Recently, the project web site was also closed. Sun Microsystems still offers a SKIP product and documentation. Even though the product is still called SKIP, it seems to also support non-SKIP IPsec.

Networking

• TERP. (2001-2002)
  Traffic Engineering Reference Platform for the IBM PowerNP.
• Hardware Packet Processing/FPX. (2000-2001)
  Fast packet processing on FPGAs; transfer of Operating Systems design methodology to hardware packet processing.
• Forwarding. (1996-2001)
  Fast forwarding and packet classification algorithms.

Distributed Systems

• P2P. (2001-)
  Efficient, stateless Peer-to-peer data distribution.
• Fuzzycast. (2000-)
  Achieving scalable and efficient video-on-demand over multicast.
• Multicast. (1999-2001)
  Scalability for multicast mechanisms and applications; includes our ALMI application-layer multicast mechanism.
• VersaKey. (1997-1999)
  Versatile key management for large and dynamic groups.
• Da CaPo++. (1996-1999)
  Flexible middleware for multimedia communications.

Some Other Projects

• Maintainer of the TIK PGP Keyserver, the swiss contribution to the world-wide PGP Key Server Network. (1996-1999)
