<p>A data transfer device, a data transfer method, a data communication system and a program for reducing data transfer delays in intermediate network devices in a wide area Ethernet network. A MAC (Media Access Control) frame having a length of longer than or equal to N bytes is divided into divided frames each having a length of M bytes (N > M) in edge devices which form a wide area Ethernet network. Thus, a maximum limit is provided on the length of MAC frames which are transmitted in the network. Consequently, it is possible to eliminate delays in the transmission of other MAC frames in the network. In the case of transmitting divided MAC frames from inside to outside the network, the divided MAC frames are reassembled into an original MAC frame. <IMAGE></p> |
