Description
Summary:碩士 === 大同大學 === 資訊工程研究所 === 89 === CORBA applications can transparently use services running on the client’s machine, on the local-area network, or across the Internet. Standard CORBA services help the application locate service instances, but do not provide a mechanism to identify service instance that will give good performance. The LBBroker we present in the thesis act as an extended location service. It probes and uses the weights vector to evaluate probe results then selects the services that will give optimal performance. Test with a distributed MD-Calculation application show that service instance chosen by LBBroker give better performance than service instances chosen by round-robin or random selection in local-area network and Internet environments.
