    • It is described a concept for a service selection of at least two services of a composite service wherein a composite service description (100) of the composite service includes at least two service templates (102a, 102b, 102c), each of which defines at least one constraint for a service wherein the service is to be executed in place of the service template to thereby constitute part of the composite service. From service database there is selected for each service template a corresponding candidate set comprising at least one service matching the at least one constraint of the service template. Subsequently or at least partially simultaneously for each of the at least two service templates (102a, 102b, 102c), from the corresponding candidate set one service is selected so as to provide, based on a predetermined cost metric, for a reduced composition cost. The predetermined cost metric may include a latency metric, an energy efficiency metric, a co-location metric or a traffic metric, etc.
    • 描述了用于组合服务的至少两个服务的服务选择的概念,其中组合服务的组合服务描述(100)包括至少两个服务模板(102a,102b,102c),每个服务模板至少限定 服务的一个约束,其中将执行服务来代替服务模板,从而构成复合服务的一部分。 从服务数据库,为每个服务模板选择包括与服务模板的至少一个约束匹配的至少一个服务的对应候选集。 随后或至少部分地同时对于至少两个服务模板(102a,102b,102c)中的每一个,从相应的候选集合中选择一个服务,以便基于预定的成本度量来提供降低的组合成本。 预定成本度量可以包括等待时间度量,能量效率度量,共位置度量或业务度量等。
