中文摘要：
作为可靠服务的一条流行途径面向的建筑学(SOA ) ，一个服务水池收集为完成需要的可靠性由不同服务提供者提供一样的功能的一套服务。不管多么在可靠性和另外的重要质量之间的折衷，例如，性能，不得不被考虑，一个服务水池的构造和管理成为更多建筑群。在这篇论文，解决这个问题的一条自动化途径被介绍。在典型三角 SOA 模型，基于服务水池的调查对服务水池的有效性和效率批评的二挑战被识别，包括哪个服务应该被一个水池举行并且什么订这些服务被调用在里面。一套算法被设计到地址二挑战然后一个服务水池能自动地在多项式时间为给定的可靠性和性能需求被构造并且设法。Theapproach 在 J2EE 上被表明在不同分享的算法之间的基于的服务站台和比较结果被评估。
英文摘要：
As a popular approach to dependable service oriented architecture （SOA）, a service pool collects a set of services that provide the same functionality by different service providers for achieving desired reliability. However, if the tradeoff between reliability and other important qualities, e.g., performance, has to be considered, the construction and management of a service pool become much more complex. In this paper, an automated approach to this problem is presented. Based on the investigation of service pools in the typical triangle SOA model, two challenges critical to the effectiveness and efficiency of service pools are identified, including which services should be held by a pool and what order these services are invoked in. A set of algorithms are designed to address the two challenges and then a service pool can be automatically constructed and managed for given reliability and performance requirements in polynomial time. The approach is demonstrated on a J2EE based service platform and the comparison results between different pooling algorithms are evaluated.
