Nowadays, the complexity of global video products has substantially increased. They are composed of several associated services whose functionalities need to adapt across heterogeneous networks with different technologies and administrative domains. Each of these domains has different operational procedures; therefore, the comprehensive management of multi-domain services presents serious challenges. This paper discusses an approach to service management linking fault diagnosis system and Business Processes for Telefónica's global video service. The main contribution of this paper is the proposal of an extended service management architecture based on Multi Agent Systems able to integrate the fault diagnosis with other different service management functionalities. This architecture includes a distributed set of agents able to coordinate their actions under the umbrella of a Shared Knowledge Plane, inferring and sharing their knowledge with semantic techniques and three types of automatic reasoning: heterogeneous, ontology-based and Bayesian reasoning. This proposal has been deployed and validated in a real scenario in the video service offered by Telefónica Latam.
如今，全球视频产品的复杂性大幅增加。它们由多个相关服务组成，这些服务的功能需要在具有不同技术和管理域的异构网络中进行适配。每个域都有不同的操作流程；因此，多域服务的综合管理面临严峻挑战。本文讨论了一种将故障诊断系统与西班牙电信全球视频服务的业务流程相链接的服务管理方法。本文的主要贡献是提出了一种基于多智能体系统的扩展服务管理架构，该架构能够将故障诊断与其他不同的服务管理功能集成在一起。该架构包括一组分布式智能体，它们能够在共享知识平面的框架下协调行动，运用语义技术以及三种自动推理类型（异构推理、基于本体的推理和贝叶斯推理）来推断和共享知识。该提议已在西班牙电信拉美公司提供的视频服务的实际场景中进行了部署和验证。
