This paper introduces admission control models for accepting or denying requests to differentiated media streaming services to avoid overload and to use multiple scarce server resources efficiently. The decision models are based on deterministic and stochastic mathematical programming techniques and use a number of heuristics to determine model parameters at run-time. In contrast to existing admission...
The following topics are dealt with: enterprise computing; e-commerce privacy and security; e-service; resource management; media management; business collaboration and semantic Web service composition.
It is the responsibility of an e-commerce provider to provision resources to ensure that the performance of the services provided by an e-commerce application is acceptable. A quantitative estimate of the performance expected from the site, obtained from the expected workload imposed on the application, may allow the provider to make informed decisions with respect to the right level of resources...
Grid technology denotes a computing paradigm in which computing resources are shared across geographical and administrative boundaries. Market-based mechanisms are deemed promising to provide a better fit to grids' strategic and dynamic nature than classic technical schedulers. In this paper, we present a deterministic heuristic that achieves the distinct trade-off between scalability by approximation...
