FIELD: communication technique.
SUBSTANCE: invention relates to systems for transmitting data via an Ethernet, particularly for setting up an inter-car communication network on railway transport. Method of providing communication in Ethernet train line involves connection to physically separated network devices of rolling stock for further data exchange between them. For each network device, using the designated port of the switch, selecting subnets for each class of network devices, determining the orientation and serial number of cars, dynamic allocation of IP addresses is carried out and power is supplied to network devices based on Power other Ethernet technology.
EFFECT: preservation of serviceable condition of system in case of occurrence of various failures.
