TTDP(Train Topology Discovery Protocol)
Train topology is dynamic and frequently changes since carriages are constantly added, removed, or replaced. Every time
the order of the carriages changes, the network must be reconfigured, which is very time-consuming and prone to errors
if it's done manually.
TTDP (Train Topology Discovery Protocol) protocol has thus been developed to enhance the efficiency of railway network
reconfiguration. The protocol enables Ethernet switches to negotiate automatically with other network devices after
the network topology is changed and will reassign an IP address to the network devices based on the new order of
the carriages. Therefore IT staff or operators do not need to reconfigure the network devices manually at all. With this
technology, train operators can vastly improve their operational efficiency and minimize configuration errors.
