Data frame construction method and data processing method according to data frame in synchronous Ethernet
First Claim
1. A method for constructing a frame of data for transmission by each Ethernet device in a synchronous Ethernet, the method comprising the steps of:
- receiving the data for transmission and confirming whether or not the data for transmission are synchronous data, wherein when the received data are synchronous data, marking the data as 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 the data as 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.

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.

5. A method for enabling each Ethernet device to process inputted data in a synchronous Ethernet, the method comprising the steps of:
-
a) receiving the data by the Ethernet device and confirming whether or not each frame of the data is a synchronous frame;
b) when the frame is the synchronous frame, confirming whether or not a slot in the corresponding frame is a slot in which a slot routing path has been set for the Ethernet device;
c) when the slot in which the slot routing path has been set, transmitting the slot through a corresponding slot routing path, and when the slot is not a slot in which the slot routing path has been set, transmitting the slot to another Ethernet device through a physical layer of the Ethernet device; and
d) when the frame is an asynchronous frame, transmitting the corresponding frame to a MAC layer of the Ethernet device. - View Dependent Claims (6)

7. An apparatus in an Ethernet device for constructing a frame of data for transmission in a synchronous Ethernet format, the apparatus comprising:
-
a processor in communication with a memory, the processor executing code for;
receiving data for transmission;
determining whether data for transmission are synchronous data; and
marking in a preamble of the frame when the data are synchronous and constructing a synchronous frame by including the received data into a data portion of the frame which does not contain a MAC header. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
