Lay Summary (Englisch)

Lay summary
The goal of this research project is to develop protocol implementations with inherent self-healing functionality. We wish to obtain intrinsically robust protocol implementations where errors can occur in the "core" protocol implementation as well as in the detection and correction part. The software must be able to detect and replace misbehaving software parts at run time, while continuing to provide the service, although perhaps less efficiently during the transitory repair phase.In todays protocols, these activities are mostly handled manually, where network managers monitor the network for anomalous performance or react on user complaints about service disruptions. Resilient and self-healing protocols would enable safe automated installation of new protocols, protocol upgrade, and run-time customization of protocols to adapt to different network situations.A key element is that we have to use continuously self-rewriting and redundant software. If some elements of the software becomes non-functional, the other working parts will quickly replace them. Our approach uses artificial chemistries where molecules can easily be mapped to data packets in a computer network.

The ``Self-Healing Protocols'' project, running since July 2007, hadas its original goal the hardening of protocol implementations at thecode level such that the implementation can absorb and recover from acode deletion attack. We believe that we have achieved a {\em breakthrough} in two ways. First, we have developed a solution basedon artificial chemistries where we could convince ourselves that thisproblem can be solved for real. And second, we managed to translate andgeneralize these results for the computer networking community and toget a peer review on our approach right away: Our papersubmission~\cite{MeTs09a} wasaccepted for Hotnets09, the novelty track of the prestigious ACMSIGOMM, which this year had an acceptance rate of~20 out of130~papers.Due to an oversight, we missed the application deadline for extendingthe Self-Healing Protocol project beyond the initial two years. Thisapplication is for funding the final 9 additional months needed to``round up'' the results achieved so far and for the editing of thedoctrate thesis of Mr Thomas Meyer.
