Abstract :
The eQoS framework represents a first step in a systematic approach to provisioning user- perceived page-view response time differentiation and assurance. It deploys a model predictive feedback controller approach to adjust the processing rate allocated to each class of requests dynamically in response to measured performance deviation.
