<p><P>PROBLEM TO BE SOLVED: To carry out communication processing by allowing network relay devices using communication paths to synchronize with each other for operation thereof even if the devices are disposed on the data communication paths. <P>SOLUTION: A synchronous transfer device for controlling synchronization of the network relay devices of a non-synchronous communication network includes: a clock extraction portion for extracting clock from data inputted to the network relay device; a synchronization control portion for allowing the data outputted from the network relay device to synchronize with timing of the clock extracted by the clock extraction portion; and a data transmission portion for transmitting the data synchronized by the synchronization control portion. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
