Abstract: In view of the potential risks related to reliability and security when the train control data are carried by the public networks of telecom operators, this paper studies the reliability technologies for train-wayside wireless communication of rail transport based on the public network, and presents the adoption of the L2TP tunneling technology and IPSec encryption technology to protect the transmission channels and improve the reliability of data transmission. Based on the application locations of these two technologies, three network deployment schemes are proposed for train-wayside wireless communication, and comparative analysis is made among these three schemes.

Key words: train-wayside wireless communication, virtual private network, tunneling technology, encryption technology
