Dynamic Adaptation of Stability Periods for Service Level Agreements
Ref: HURRAY-TR-060801 Publication Date: 16 to 18, Aug, 2006Abstract:
A QoS adaptation to dynamically changing system conditions that takes into consideration the user's constraints on the stability of service provisioning is presented. The goal is to allow the system to make QoS adaptation decisions in response to fluctuations in task traffic flow, under the control of the user. We pay special attention to the case where monitoring the stability period and resource load variation of Service Level Agreements for different types of services is used to dynamically adapt future stability periods, according to a feedback control scheme. System's adaptation behaviour can be configured according to a desired confidence level on future resource usage. The viability of the proposed approach is validated by preliminary experiments.
