Abstract:
Using cache in the voice platform based on VoiceXML (voice extensible makeup language) could reduce the cost of network bandwidth, server-load and access delay. By analyzing the cache model of voice platform, the fitting & predicting algorithm is proposed. It estimates the validity of the cached document by performing parameter fits to stochastic distribution and predicting the change probability of VoiceXML documents within a certain period. Simulated research indicates the algorithm surpasses the Alex protocol and can obtain a stale ratio lower than 1/10000 to meet the demand of the voice platform while effectively enhance the system performance
