摘　　要：随着网络访问资源量的不断增加,导致Web服务资源特征信息的定位难度增大,Web服务资源若不能均衡分配,很容易出现需求“扎堆”现象或服务资源“饥饿”问题,造成服务资源浪费。针对上述问题,以特征信息定位技术为基础构建一种新的Web服务资源均衡分配模型。基于任务重要性、紧急性判断队列优先级,组建服务需求队列,并向Web服务资源发送资源需求标准。对符合用户使用需求的Web服务资源进行检索,并分析负载特征,以对特征信息进行精准定位。根据特征信息定位结果,结合资源服务资源与匹配度计算结果,构建分配模型。实验结果表明:与多种传统的分配模型相比,在所研究模型应用下,Web服务器空闲率达到0.45%、负载均衡率达到90%以上,说明所构建模型设计的分配方案更为合理。With the increasing amount of network access resources,it is more difficult to locate the characteristic information of web service resources. If the Web service resources cannot be evenly distributed,it is easy to have the phenomenon of demand "clustering" or the problem of "hunger" of service resources,resulting in the waste of service resources. To solve the above problems,a new balanced allocation model of Web service resources is constructed based on feature information location technology.The priority of the queue is judged based on the importance and urgency of the task,the service demand queue is established,and the resource demand standard is sent to the Web service resources. The Web service resources that meet the needs of users are searched,and the load characteristics are analyzed to accurately locate the characteristic information. According to the location results of feature information,combined with the calculation results of resource service resources and matching degree,the allocation model is constructed. The experimental results show that compared with a variety of traditional allocation models,under the application of the studied model,the idle rate of web server reaches 0.45% and the load balancing rate reaches more than 90%,indicating that the allocation scheme designed by the constructed model is more reasonable.
