| 摘 要： | 随着Web服务的广泛应用,如何在有限的资源下来提高Web服务的QoS(quality of service)已经成为关注的热点问题.通过设计一个灵活的选择结构BS-Serv(bidirectional selection-serv),提供者使用多维背包算法,请求者使用需要等待时间原则,来实现提供者和请求者的双向选择,从而即保证了提供者的资源能达到最充分的利用,提高了Web服务的QoS,还保证了请求者对服务的满意.详细分析了多维背包算法和请求者需要等待原则的设计,并讨论了结构的实现.

| Abstract: | With the widespread application of the web services,how to improve the QoS(quality of service) of the web services under the limited resource becomes the attentive hot spot question.A flexible selection structure BS-Serv(bidirectional selection-serv) is de-signed,the provider use the multidimensional knapsack arithmetic,the requestor use the needed wait time principle,to realize the bi-directional selection between the provider and the requestor,thus not only make the most adequately use of the provider's resource,im-prove the QoS of the web services,but also guarantee the satisfaction of the requestor to the web services.The multidimensional knapsack arithmetic and the needed wait time principle of the requestor are analyzed in detail,and the implementation of the structure is also di-scussed. |
