A property-based clustering approach for the CORBA Trading Service

摘要

The CORBA Trading Service is an object service advertiser forheterogeneous distributed computing environments. Current approaches forthe design and implementation of such a CORBA service do not deal withsome of the major problems of searching for service offers inlarge-scale distributed systems, namely performance and scalabilityproblems. This paper proposes an appropriate approach for clusteringservice offers based on the service properties, in order to enhance theefficiency of the trading service. The proposed approach clustersservice offers within a hierarchy of contexts by specialisation ofproperty sets. Performance results of the proposed clustering approachare discussed, and the benefits of including clustering of propertieswith the CORBA Trading Service are shown
