摘要

我们解决了服务组合中的故障问题。当组合中的服务发展或变得不可用时,就会发生此类故障。我们的目标是分析这些故障并建议可能的服务修复。我们从服务和服务组合的正式模型开始。在此模型中,服务被抽象为将输入域映射到输出域的函数,其语义知识仅限于相对较短的输入-输出对表。然后在两个函数操作符的帮助下形成服务组合。然后,我们设计了一种技术,通过提供建议修复的排序列表来支持程序员调试服务故障。维修可以替代故障的组件服务或包含故障的组件的任何部分。最后,我们描述了验证我们技术的实验。

Recommending Service Repairs
We address the issue of failure in service compositions. Such failures occur when a service in the composition evolves or becomes unavailable. Our goal is to analyze these failures and recommend possible service repairs. We begin with a formal model of services and service compositions. In this model, services are abstracted as functions that map input domains to output domains and knowledge of their semantics is restricted to a relatively short table of input-output pairs. Service compositions are then formed with the help of two functional operators. We then design a technique to support programmers in debugging service failure by offering a ranked list of suggested repairs. The repairs may substitute the failed component service or any portion of the composition that contains it. Finally, we describe experiments that validate our technique.
