Design And Implementation Of Key Modules And Caching Mechanism For VAP

In order to push the new voice services more quickly and better and decrease the operating risk, CMCC plans to build an independent voice value-added service platform. This platform will open to service/content providers and enable them to provide more new services to customers. VoiceXML (Voice Extensible Markup Language) is used in this system as the service logic language.VAP (the Voice Value- Added service platform) is the core module of the speech contents business system, completing the speech call sign to continue and the Voice Value- Added service business to be explained and run.First, author gives an introduction of VAP, including the position in the whole set of speech contents business system, the logic system structure, the function system and the total design, then gives the design and implementation of Vxi, Inet and Cache which are three key modules in VoiceXML business performance environment.Second, the design and implementation of Caching Mechanism for VAP is mainly introduced. The whole mechanism has four greatest parts, which is hierarchy cache, contents cache, the hierarchy and contents combine cache and rewriting the VoiceXML cached. Among them the hierarchy and contents combine cache namely the VoiceXML DOM (the Document Object Model) tree caching mechanism and rewriting the VoiceXML cached mechanism are put forward newly, they lead to quality promote of VAP greatly.The VoiceXML DOM (the Document Object Model) tree caching mechanism can be thought as an outcome that combines the hierarchy...
