Research Of Reliability Model Based On Web Service

Along with the computer the rapid development of information technology,Internet has evolved into a distributed computing environment. The Web servicequality has been widespread concern. The Web service quality reliability as oneof the most important aspects in the choice, customer service is a high degree ofattention, determines whether the Web service key to success. At present,domestic and foreign scholars have made a lot of Web service reliability analysisresearch, has achieved some results.This article in view of the current Web service reliability study of theexistence of the problem, a profound analysis of the Web service reliabilitymodel and traditional software reliability model differences and characteristics,studied the Web service measurement model in the presence of precision problem,proposed one kind based on the control-structure of the improved model and thevalidity of the model and other problems. The main work of this paper includes:1. Comprehensive analysis of conventional software reliability models, andthe classic software reliability models were classified and summed up thereliability models assume that the general steps. Analysis of Web service modeland traditional software model is different and limitations, analysis of softwarereliability model to study Web reference service reliability model of meaning2. A summary of existing Web service reliability technology, according tothe Web service reliability measurement model, analysis of the Web servicereliability not only with the service between the structure of relations, and willserve a combination of conditions relating to the reliability. So, the Web servicereliability model,can not reflect the service reliability. In order to improve thereliability of the precision of the model, this paper presents a improved modelbased on control structure. The model takes into account not only the service between structural problems, the combination of reliability as the importantfactors to consider, make the original model is more accurate, more in line withthe actual application environment.3. Combination of online shopping system, the reliability model is appliedto the example verification. Through the simulation experiment, validate thereliability model is effective, and the precision of the model prediction. Analysiscombinatorial conditions reliability sensitivity and conditions of service to thewhole effect.
