| Abstract: | With the increased number of users of China mobile, people rely more and more on the 3G/4G wireless network, as well as the wireless LAN Wi-Fi hotspot. According to the statistics, the daily passenger volume of China high-speed railway reached 5 million to provide Wi-Fi hotspot service for passengers in the high-speed railway station and on the train, could greatly improve passenger travel experience, offer convenience for railway diversified business. This article discussed the method to synchronize the big data files in the Railway Wi-Fi Operation Service System from the aspects of Rsync file synchronization, data synchronization scheme, network topology structure, and so on. Combined with the reality, the specific implementation scheme was given. |
