基于QoS的服务个性化选择路由

Personalized service routing based on QoS

在服务个性化选择路由已有研究的基础上,提出将功能相同的服务按照不同QoS(quality of service)属性值进行排队的方法,得到所选属性对应的若干排队。在企业服务总线(enterprise service bus,ESB)平台上搭建服务总体流程对这些排队加以利用,实验结果表明,相较按比例值进行个性化选择路由,利用排队的个性化选择路由在服务选择时间方面虽没有较大差异,但更加简便易行,在最大程度上保证了公平性,排队后选择的服务更能满足用户需求条件。

Based on the existing researches of personalized service routing,a method was proposed,in which services with the same functionalities were queued according to different values of the QoS attributes,and several queues corresponding to selected QoS attributes were got.The overall flow can use the queues on the ESB platform.The results of experiments shows that,comparing with the personalized service routing using the proportional value,although there is no big difference on the selecting time between two methods,the personalized service routing using the queues is more simple,moreover,the proposed method can ensure the fairness to the maximum extent and then better meet the user needs.
