Discovery of web services with a P2P network

Abstract

In the concept of Web Services, Universal Description, Discovery and Integration is still the weakest part. As a central instance, it does not easily scale to a growing number of users and lacks acceptance by the industry. In Peer-to-Peer Networks, which are highly popular, discovery of resources is one of the strongest parts. A central registry is not required when integrating Web Services in a Peer-to-Peer network. Each Web Service is responsible for itself and the Peer-to-Peer Network provides the framework for discovery, publication and registration of Web Services. This paper shows, how both technologies fit together and gives details on both structure and design of the Peer-to-Peer network. This results in a more feasible solution than the central Universal Description, Discovery and Integration infrastructure and provides an easy way for registration, publishing and discovery of Web Services. © Springer-Verlag 2004.
