Abstract: Web server registration(UDDI) is an important part of the SOA. To solve the Single Point of Failure and its expansibility in UDDI, the researches proposed some solutions such as the Affiliate Registry and Peer-to-Peer, but their effects do not meet the need. By selecting a server-node at dense network area,the papar proposed a new model SPSR-UDDI (Super Peer and Semantic Routing UDDI). The connection between nodes will be dynamically adjusted by the principle of vertex weight priority, which makes that whole time of server response be the shortest. The paper built a model of network evolvement to achieve network's self-organized evolvcment process. The paper gave our experiment results that validate the validity of new strategy.
