To actualize remote wakeup by detecting a sleep mode release data sequence, using a network card made compatible with parallel transfer.
The sleep mode release data sequence is configured, such that prefix data in 4 bytes whose values are all FFh are repeated by a prescribed number of times n (e.g. four times), principal data, comprising a0 being the least significant byte of a MAC address composed of 4 bytes; a1 corresponding to a second byte of the MAC address composed of 4 bytes; a2 composed of 4 bytes; a3 composed of 4 bytes; a4 composed of 4 bytes; and the most significant byte a5 composed of 4 bytes, in succession are repeated by a prescribed number of times m (e.g. eight times), and postfix data in 4 bytes whose values are all FFh are repeated by a prescribed number of times p (e.g. three times). The sleep mode release data sequence is inserted to an optional part and received by four lanes, and the same lane sleep mode release data sequence is received by any lane. The technology relating to the present invention can be applied to network nodes for personal computers or the like.
