About us

The Internet is the greatest innovation of our lifetimes. In concert with a host of other great innovations such as the personal computer and mobile communications, it is the backbone of the increasingly digital reality of the 21st century.

The objective of the Research Group in Networking (AG-RN) is to make the net work better — both with a view to technical improvements and by empowering its participants and fostering innovation.

One avenue towards this goal is contributing to standardization, since standards enable choice and ultimately the creation of a marketplace. AG-RN focuses these efforts on the Internet Engineering Task Force, IETF. So far, more than 20 RFCs have been created by TZI authors or based on significant contributions from the TZI, and work is ongoing. These Internet standard documents cover areas as diverse as media over IP (RTP), integrated services over slow links (ISSLL), reliable multicast (NORM), robust header compression (ROHC), and wireless embedded Internet (6lowpan).

Another important enabler for the increasingly digital reality is the ability of its participants to rely on its security. AG-RN addresses informations security both with respect to protocol/IT security, where major work has gone into the foundations of role-based access control (RBAC) and the detection of security violations, as well as with respect to information security as a process. In the latter area, the focus is both on supporting security in Agile Development and on web-based support for cooperative security processes.

The research group is co-led by Prof. Ute Bormann and Prof. Carsten Bormann. Dr. Karsten Sohr coordinates the area of Information Security for TZI. Researchers at the doctorate level also include Dr. Olaf Bergmann, Dr. Thomas Kemmerich, and Dr. Oliver Laumann. For more details, see [team].
