A Zone Routing Algorithm for Service Network

The increasing number of available open services demands distributed architectures to promote scalability to enable their precise and efficient retrieval. As web services proliferate, it is more and more difficult to find suitable services and further compose them into complex applications automatically. In this paper, a novel service infrastructure named Service Network(ServNet), which is constructed on the basis of service routers and service switches, is proposed to deploy and manage large-scale services. Furthermore, the zone routing algorithm (ZRA) combines the advantages of the proactive and reactive approaches by maintaining an up-to-date topological map of a zone centered on each service node. Experimental evaluations confirmed the efficiency in terms of accuracy of query and network traffic.
