This manuscript discusses a new approach for estimating cost adjustment for projects that are billed using function points. The baseline for estimation is assumed to be a set of projects with known effort and delivered function points. The proposed method uses the concept of variable productivity and builds a framework based on best unbiased linear estimator to accurately estimate the needed effort...
IT service providers are increasingly utilizing globally distributed resources to drive down costs, reduce risk through diversification and gain access to a larger talent pool. However, fostering effective collaboration among geographically distributed resources is a difficult challenge. In this paper, we present our initial attempt to quantify the increased overhead in leveraging distributed resources...
We develop algorithms to provide Quality of Service (QoS) support for prioritized, bandwidth-adaptive and fair media streaming using a multimedia server cluster. We formulate the underlying related problems of prioritized client admission control, redirection to appropriate streaming server, adaptive client quality control, and server load-balancing as one combined optimization. This optimization...
Service-oriented architectures allow content providers to enable easy and transparent access to multimedia content for their clients as well as outsource non-strategic streaming services to third-party providers. We design a QoS framework and associated algorithms that can provide prioritized and fair media streaming based on service level agreements. We formulate the QoS support as a multiple choice...
