Composite Service Management Framework for QoS Guarantee
-
Abstract
In this paper, a composite service management framework with QoS guarantee is presented, which is based on trustworthy service middleware architecture.In this framework, algorithms for QoS plan and service selection are presented.In addition, re-negotiation mechanism in upper layer and composite service scheduling mechanism in lower layer together provide two-layer QoS guarantee, which maximizes users' QoS requirements.Finally the experiments ensure the validity of the proposed framework and corresponding algorithms.
