Aiming at the problem that the web services are in a low availability of universal description discovery and integration(UDDI),availability requirement of difference role of SOA(service-oriented architecture) is analyzed,and then an availability-guaranteed model was constructed for service discovery.This model can measure the availability of web service via polling algorithm to identify availability rate of UDDI.When the availability rate falls below threshold,the polling cycle will be changed to improve the monitor for web service.This not only ensure the availability of UDDI but also guarantee the availability of web service for Users with service availability assessment.
