Abstract:
Facing the optimal problem of meteorological large data files access upon Virtual Private Dial-up Networks (VPDN), transport back of reliable radar data and optimize retrieval of single-server is studied. Focusing on the requirements and radar data application, such as images split joint of multiple weather radars, the strategies of data division and storage are proposed, and an evaluation model named Quality of Experience based on Reliability and Time (QoE-RT) is presented. Consequently, Adaptive File Access Control (AFAC) algorithm is designed and implement, which is consisted of reliable file transmission, rapid file retrieval, file size adjustment and service quality evaluation. The performance is verified by experiments of the file retrieval and transmission in actual environment, which shows that the file access time is decreased by 20%, transport success rate is more than 95%, and the QoE is significantly improved.
