Transport system and transport apparatus

A transport system, including:

• a first transport apparatus for transporting data that is received by a plurality of first interfaces;
• and
• a second transport apparatus for receiving data that is transported from the first transport apparatus and transmitting the data from a plurality of second interfaces,
• the first transport apparatus including:
• a port information management unit for obtaining, for each of the plurality of first interfaces, port information which includes a type of the each of the plurality of first interfaces, a transport rate of the each of the plurality of first interfaces, and a physical lane count of physical lanes leading from the each of the plurality of first interfaces into the first transport apparatus, and for determining, based on the obtained port information, a virtual lane count of virtual lanes into which the physical lanes leading from the each of the plurality of first interfaces are converted;
• virtual lane creating units, which are each connected to physical lanes leading from the each of the plurality of first interfaces, for setting, for the each of the plurality of first interfaces, as many virtual lanes as the virtual lane count determined by the port information management unit;
• a lane information creating unit for creating, based on the port information, lane information which associates the each of the plurality of first interfaces, the physical lane count of physical lanes leading from the each of the plurality of first interfaces, and identification information of virtual lanes that are set by the virtual lane creating units in association with the physical lanes;
• and
• a multiplexing unit for multiplexing data that is transported along the virtual lanes, and for inserting the lane information which has been created by the lane information creating unit in an invalid data field which is generated when the data is multiplexed,
• the second transport apparatus including:
• a demultiplexing unit for receiving the multiplexed data which has been multiplexed by the multiplexing unit, and for obtaining the lane information while demultiplexing the multiplexed data for the each of the plurality of first interfaces separately;
• and
• physical lane creating units, which are connected to virtual lanes leading from the demultiplexing unit, for setting, based on the lane information obtained by the demultiplexing unit, for each of the plurality of second interfaces, physical lanes that are connected to the each of the plurality of second interfaces.
