ABSTRACT
The complexity of resource allocation is further increased by several factors. First, in many distributed systems, the resources are in fact owned by multiple organizations. Second, the satisfaction of users and the performance of applications are determined by the simultaneous application of multiple resources. For example, a multimedia server application requires I/O bandwidth to retrieve content, CPU time to execute server logic and protocols, and networking bandwidth to deliver the content to clients. The performance of applications may also be altered by trading resources. For example, a multimedia server application may perform better by releasing memory and acquiring higher CPU priority, resulting in smaller buffers for I/O and networking but improving the performance of the communication protocol execution.
