Abstract
本发明涉及计算机领域,公开了一种基于QoS的分布式web服务选择方法,采用分布式的方式进行web服务的选择,通过将web服务选择这个需要非常巨大的计算能力才能解决的大问题分解成为很多小的部分,将这些小的部分分配给许多计算进行并行处理,最后把每个计算结果合并起来得到最终结果。本发明通过pre-prune-refine模型,在不同的机器上进行高效地并行计算,经过pre-prune过程提前删除一些不满足条件的web服务,显著地缩短响应时间,从而能够快速灵活地找到满足用户需求的服务。由于中间产生的输入输出都是临时文件,不会产生额外的输入输出开销,能够显著增强网络的传送效率,大大提高了选择的效率。
The present invention relates to the field of computers, and discloses a QoS-based distributed web service selection method, which uses a distributed method to select web services, and decomposes the large problem of web service selection, which requires a very large computing power to be solved, into A lot of small parts, assign these small parts to many calculations for parallel processing, and finally combine the results of each calculation to get the final result. The present invention uses the pre-prune-refine model to perform efficient parallel computing on different machines, delete some web services that do not meet the conditions in advance through the pre-prune process, and significantly shorten the response time, so that it can quickly and flexibly find satisfactory user required services. Since the input and output generated in the middle are all temporary files, no additional input and output overhead will be generated, which can significantly enhance the transmission efficiency of the network and greatly improve the efficiency of selection.
