Abstract: 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.

A phase adjuster detects a reference VC-3 channel of VC-3 channels which make up a virtual concatenation based on detected MFI values. A write controller writes frame data into a phase adjustment memory based on a write permission signal from the phase adjuster and data valid/invalid information. A write frame manager manages the frame data written in the phase adjustment memory with respect to each of the VC-3 channels and generates a read permission signal for the frame data whose all VC-3 channels of the concatenation have been written. A read controller reads the frame data from phase adjustment memory according to the read permission signal.
