SWITCH EN50155 – Protocol LTDP HOWTO
In most of train application, many train cars will be shifted according to different destination, which often becomes a maintenance issue when any car changes. As the different car devices were set with different IP address that would need to migrate into the same IP without any manual setting to keep the original train network. With LTDP-aware DHCP server, Lantech EN50155 switches can discover the current IP addresses and enable the switch to exchange the IP address when any car is merged.
LTDP can also react on the link failure or node failure to keep the original IP range and maintain the remaining network function until the replacement is in place.
It can also keep the config file when switch is swapped.
