Abstract:In view of the complexity in terrain of Sichuan Province, the large number of meteorological stations as well as the fact that the meteorological information network system was seriously damaged in various natural disasters, this study introduces the application of IRF method to upgrade transformation of virtual technology to the new provincial meteorological information network system. The MAD BFD detection is used to improve the reliability and stability of the network system through the integration of resources, ultimately ensuring the meteorological business efficiency. In the upgrading of equipment, the whole network link bandwidth and QoS also have a new design, achieving the integration of meteorological information network systems at three levels:provincial, city, and state level. Results show that the system is stable and reliable, and it embodies more advantages of virtualization framework. In short, it meets the needs of meteorological service to the network over the next few years.
