<p>An example of a data transport system includes transport nodes of a transport network, communication devices which communicate via the transport network, and a transport network logical path management server for setting logical paths between the transport nodes within the transport network, and a logical path control server. In a case where a first communication device is newly connected with a first transport node, the first communication device transmits control data to a logical path control server via the first transport node. The logical path control server obtains information about a connection relation between the newly connected first communication device and the first transport node from the control data, and establishes a logical path between the first communication device and a second communication device based on the obtained information about the connection relation and on information about logical paths between transport nodes in a logical path database.</p> |
