My Work

Stream Control Transmission Protocol (SCTP)

The Stream Control Transmission Protocol (SCTP) is an advanced Transport Layer protocol which may some day replace TCP. Focus of my research on SCTP is the optimization of Concurrent Multipath Transfer (CMT), which means to simultaneously utilise multiple paths within the network to increase application data throughput.
For more details on my project, see The SCTP Project Page!

Reliable Server Pooling (RSerPool)

The Computer Networking Technology group is involved in research on and standardization of Reliable Server Pooling (RSerPool), a novel server pooling framework currently under standardization by the IETF. I have realized a full, Open Source prototype implementation of RSerPool, developed a simulation model in OMNeT++ for research purposes and I am furthermore involved in standardization by the contribution of multiple Working Group drafts and individual submissions.
For more details on my project, see The rsplib Project Page!

Flow Routing

Flow routing is a novel concept for efficient high-speed routing. Combining the flow routing concept with Quality of Service (QoS), a network can efficiently cope with the requirements of modern multimedia applications. The main goal of our flow routing project is to develop, evaluate and finally also standardize a QoS concept for assuring the bandwidth requirements of multimedia applications – requiring only minimal signalling overhead.

My Software Projects

• 2011 – ...: The RTP Audio NextGen System
  RTP Audio NextGen is an audio streaming system with support for SCTP as well as UDP transport. It is a highly advanced and reworked version of the former RTP Audio system with support for SCTP streams and SCTP partial reliability. Furthermore, it also contains a QoS management interface. RTP Audio NextGen may use layered encoding, that is the audio quality may be adapted according to QoS constraints. The main purpose of this tool is to support transport protocol and QoS research, by providing a realistic application for performance testing.

• 2002 – ...: The rsplib Implementation of the Reliable Server Pooling Framework
  rsplib is the Open Source implementation of the IETF's Reliable Server Pooling (RSerPool, RFC 5351) framework written in ANSI-C and C++, currently supporting Linux, FreeBSD, MacOS X and Solaris. Its intention is to validate the RSerPool drafts currently under standardization by the IETF and to verify results from my simulative research. As part of my RSerPool research in the context of my Ph.D. Thesis, multiple Internet Drafts have been contributed to the IETF's standardization process. Furthermore, the rsplib prototype has become the IETF RSerPool Working Group's reference implementation of RSerPool.

• 2009 – ...: NetPerfMeter – A TCP/UDP/SCTP/DCCP Network Performance Metering Tool
  NetPerfMeter is a network performance meter for the UDP, TCP, SCTP and DCCP transport protocols over IPv4 and IPv6. It simultaneously transmits bidirectional flows to an endpoint and measures the resulting flow bandwidths and QoS. The results are written as vector and scalar files. The vector files can be used to create PDF plots of the results.

• 2009 – ...: BibTeXConv – A BibTeX File Converter
  BibTeXConv is a BibTeX file converter which allows to export BibTeX entries to other formats, including customly defined text output. Furthermore, it provides the possibility to check URLs (including MD5, size and MIME type computations) and to verify ISBN and ISSN numbers.

• 2007 – ...: SimProcTC – A Simulation Processing Tool-Chain for OMNeT++
  SimProcTC is a model-independent, flexible and powerful tool-chain for the setup, parallel run execution, results aggregation, data analysis and debugging of OMNeT++-based simulations, using GNU R and other Open Source software under Linux.

Both packages are multi-platform and support Linux, FreeBSD, MacOS X and Solaris. This project has been a cooperation between the University of Duisburg-Essen, Computer Networking Technology Group at the Institute for Experimental Mathematics and Siemens.

• 2003: The Fractal Generator Project
  FractalGenerator is a KDE-based Open Source program under Linux – written in C++ – to generate fractal images (e.g. the Mandelbrot set). The size of the calculated images is only limited by the computer's virtual memory. This program has been developed as an example for object-oriented programming and creating Qt/KDE applications for the University of Duisburg-Essen's Linux Workshop in 2003.

• 2000 – 2001: The RTP Trace System
  An Open Source, Linux-based real-time network transmission test system using traces of various media types (MPEG 1/2, H.263, MP3, ...). It is realized in C++. This project is part of my Masters Thesis at the University of Bonn, Germany.

• 1999 – 2001: The RTP Audio System
  A Linux-based Open Source real-time network audio transmission system, supporting DiffServ, IPv6 and IPv6 flowlabels. Server and clients have been written in C++, a Java client is realized using JNI (Java Native Interface). The system has been a study project at the University of Bonn, Germany; my responsibility has been the implementation of the client/server transmission system itself, including the media codecs and the RTP protocol as well as the client GUI based on the Qt Toolkit.

• 2000: Prüfungsamt-Projekt – A Student and Exam Management Tool
  A SQL-based, Open Source database application under Linux - written in C++, using the Qt GUI Toolkit and PostgreSQL - to simplify the work of the University's exams office (Prüfungsamt) using database transactions and triggers. It has been a study project at the University of Bonn, Germany; my responsibilities have been the GUI realization and the SQL trigger implementation.

• 1994 – 2000: The MusicBox Project
  MusicBox is an audio CD playing application and management system for AmigaOS, realized in C. In particular, this software uses the SCSI interface to take advantage of all audio playing capabilities of the CD-ROM drive (e.g. channel selection, volume control, position information). This software has been shareware and is now Open Source.

• 1998 – 1999: The RandGraph Project
  The continuation of the TriGraph project (see below): the random generation of different types of graphs and their visualization, realized in C++ using the Qt GUI Toolkit.
