Transport system and transport method

A transport method performed in a transport system,

• the transport system comprising:
• a first transport apparatus for transporting data received by a plurality of first physical ports;
• and
• a second transport apparatus for receiving the data transported from the first transport apparatus and transmitting the received data from a plurality of second physical ports,
• the method comprising:
• notifying, by the first transport apparatus, for each of the plurality of first physical ports, to the second transport apparatus, a valid first lane count indicating how many of a plurality of first lanes owned by the first physical port are valid, and identification information of the first physical port that owns the valid first lanes;
• obtaining, by the second transport apparatus, for each of the plurality of second physical ports, a valid second lane count indicating how many of a plurality of second lanes owned by the second physical port are valid, and identification information of the second physical port that owns the valid second lanes;
• associating, by the second transport apparatus, based on the valid second lane count and the identification information of the second physical port, and the valid first lane count and the identification information of the first physical port which are notified by the first transport apparatus, the identification information of the first physical port and the identification information of the second physical port;
• and
• transmitting, by the second transport apparatus, when data including identification information of one of the plurality of first physical ports is transmitted from the first transport apparatus, the data from the second physical port that is identified by the identification information associated with the identification information of the one of the plurality of first physical ports which is included in the data.
