A cross-domain framework for coordinated end-to-end QoS adaptation

Abstract

In this paper, we propose a novel cross-domain QoS framework for coordinated end-to-end QoS adaptation. The framework treats each autonomous QoS service on the end-to-end path as a QoS component and models its capabilities and behavior with respect to the requirements of end-to-end QoS coordination. Based on such information, the end-to-end QoS framework runtime copes with a QoS violation by selecting a suitable QoS adaptation solution among all the end-to-end candidate choices. Preliminary simulation results demonstrate the feasibility of our framework for distributed end-to-end QoS coordination. ©2008 IEEE.
