PDUS: P2P-Based Distributed UDDI Service Discovery Approach

With the widespread deployment of web services, many challenges of the technology have emerged. Among them, the most important one is how to effectively find out the services, which can meet the requestor´s requirement, for the traditional UDDI-based centralized approach always suffers from single point of failure and performance bottlenecks. Therefore, this paper takes advantage of P2P technology and proposes a novel P2P-based Distributed UDDI Web Service Discovery (PDUS) approach to overcome these deficiencies. Besides, the paper illustrates this approach through a simple example for PDUS.
