摘要
在面向服务构架的应用流程中,服务使用者较难绑定高性能服务。该文结合Web服务质量评价模型和负载分摊策略提出一种Web服务动态绑定(DWSB)算法。DWSB算法优先选择质量等级较高的服务集合,使用轮转法从服务集合中选取负载未超重的服务为最佳服务。实验结果表明,该算法可以帮助服务使用者动态绑定性能优越的服务。
In SOA application flow, it is hard for service user to bind high performance services. Based on the load sharing strategy and the model of Web service quality evaluation, Dynamic Web Service Binding（DWSB） algorithm is presented. The DWSB algorithm first chooses the higher QoS rank services set, and uses the round robin algorithm to select a non-overload service as the best service from the set. Experimental results show that it is useful for the DWSB algorithm to help service user find high performance services.
