"目前Web Service 技術雖已被廣泛的應用，但具關鍵任務(critical mission)之應用系統仍較少採用服務導向(SOA)技術，主因在於缺乏一個系統化且有效的機制可確保與提升服務之可用性，同時，服務組合是現在SOA 技術中能帶來最多加值效益與使用彈性的核心技術，複合服務之可用性確保更是現今極為重要且待解決的研究議題。因此，本計畫希望透過一個軟體工程方法，整合服務組合之生命週期中所需要的各種服務導向機制，包含各種服務配對技術以及服務管理技術，以提升複合服務之可用性。本計畫將以先前發展之擴充契約網絡協定(Extended Contract Net Protocol) 作為基礎，發展以下技術： 1. 用於服務組合之服務配對機制： 􀂄 服務介面配對機制 􀂄 服務品質配對機制 􀂄 語意配對機制 2. 複合服務自我修復機制： 􀂄 服務品質偵測機制 􀂄 服務流程分析方法 􀂄 動態服務修復機制""Web service technologies are best exploited by composing web services. Composing multiple web services is more beneficial to users than a single service. Meanwhile, little work has been reported on highly available web services which are essential for mission critical applications. Therefore, we present a highly-available service composition framework in this project. The framework is based on an extended service composition lifecycle, which combines activities related to service composition, service discovery, and service management, as well as realizes the Extended Contract Net protocol (ECNP), which is our previous research result. According to the framework, we plan to establish two main functions: (1) a composition-based service discovery mechanism, including an interface-based service matching, a QoWS-based service matching, and a semantic service matching, and (2)a self-recovery mechanism for composite services, including a QoWS probing mechanism, a service flow analysis technology and a dynamic service recovery approach."
