摘要
为了提高基于工作流的服务合成效率,满足用户高质量的应用需求,提出了基于工作流的并行化Web服务合成方案,并提出了流程划分算法。该方案依据服务发现模块的个数,将流程中的各个服务划分到不同的服务发现模块中,以实现服务发现的并行化,进而提高了整个流程的执行效率。通过实例阐明了该方案,并且表明了该方案的高效性,最后总结了其优点。
To improve the efficiency of web services composition based on workflow and satisfy the user＇s requirements, the parallel scheme for composing web services based on workflow is put forward, and algorithm is presented.The services in flow are divided into different service discovery module according to the number of service discovery module to discover services in parallel.Thus, the executing efficiency is improved.And it is illustrated and proved that the scheme is efficient.Finally, its advantages are concluded.
