DIAMOND: Correlation-Based Anomaly Monitoring Daemon for DIME

Free registration required

Executive Summary

Distributed Interactive Multimedia Environments (DIMEs) show important dependency constraints between application and underlying system components over time. For example, the video frame rate and the underlying bandwidth usage have a strong performance dependency. Performance dependencies must also be considered among distributed components. These dependencies over a time-span form correlation relationships. Violations of such correlation relationships represent collective anomalies. Users and most specifically DIME application developers face problems of finding (detecting), localizing such anomalies, and adapting against them in real-time.
