This report describes an approach enabling automatic structural
reconfigurations of distributed applications based on configuration
management in order to compensate for node and network failures.
The major goal of the approach is to maintain the relevant application
functionality after failures automatically.This goalis achieved by a
dedicated system model and by a decentralized reconfiguration algorithm
based on it. The system model provides support for redundant application
object storage and for application-level consistency based on distributed

checkpoints. The reconfiguration algorithm detects failures, computes a
compensating configuration, and realizes this new configuration.
The report emphasizes flexibility in the sense ofadaptable levels of
fault tolerance, as well as transparency in the sense of fully-automatic
reaction to failures.
