【Abstract】 The complexity of solving large business and scientific problems demands higher requirements on the existing IT enviroment of the concerned institutions. An increase in complexity is often coupled with demands to deliver various different Qualities of Service （QoS）, relating for example to response time, throughput, availability, security and/or co-allocation of multiple resource types^[1]. In many cases it is not enough just to deliver the required QoS in a straight for ward way but the delivery also has to satisfy requirements with respect to timing, load distribution and security among others. Because of this outsourcing of such coordinated QoS （CQoS）is getting more and more common. The connection and collaboration of different resources across system boundaries and control domains is a promising approach for executing such large-scale resource and coordiation intensive jobs.更多还原
