  1. Performance Guarantees for Web Server End-Systems: A Control-Theoretical Approach Abdelzaher, Shin, Bhatti

  2. What’s It All About • Applying Control Theory to QoS

  3. What Do They Do?

  4. How Do They Do It? • Feedback Control • Using Content Adaptation (Level of Detail) • Stratified Service

  5. What Is Feedback Control?

  6. What Do You Need For Feedback Control? • Sensors / Actuators • Model

  7. Sensors • served request rate +delivered byte bandwidth

  8. Actuators • Admission control • Degradation of client QoS

  9. Transfer Function (The Model)

  10. Does It Work?

  11. How Does This Apply To AC? • Self-optimization • Self-maintenance? • Heuristics vs. Control Theory
