研究了一种组合服务混合执行机制，建立了服务间的交互协议，给出了执行环境特征模型，并在该模型基础上给出了执行模式选择规则。该机制结合了控制流、数据流全集中，控制流集中、数据流分散两种执行模式的特点，能够根据组合服务业务特性和网络环境特点动态选择执行模式，可以使得数据量较大的消息直接在服务间传递而无需通过中心节点转发。实验结果表明：组合服务混合执行机制通过在组合服务执行过程中动态选择执行模式，能够有效保证组合服务的执行效率。

A hybrid execution mechanism for composite service was researched.The interaction protocol between the services was established,and the characteristic model of the execution environment was presented.In addition,the rules for dynamically selecting the execution schema were proposed.The mechanism was a combination of execution schema of the centralized control-flow and data-flow as well as the execution schema of the centralized control-flow and decentralized data-flow,which could dynamically select the execution schema according to the feature of the business and the execution environment of the composite service.And then the message with large data amount could be transferred between the services without being redirected by the central node.The experimental results showed that the dynamic selection of the execution schemas could ensure the execution efficiency of the composite service.
