Abstract
Disclosed is a method for constructing a frame of data for transmission by each Ethernet device in a synchronous Ethernet, which comprising the steps of receiving the data for transmission and confirming whether or not the data for transmission are synchronous data, when the received data are synchronous data, marking that the data are synchronous data in a preamble of the frame and constructing a synchronous frame by including the received data into a data portion of the frame which does not contain a MAC header and when the received data are asynchronous data, marking that the data are asynchronous data in the preamble of the frame and constructing an asynchronous frame by including the received data into a data portion of the frame containing a MAC header.
