Patent ID: 7394827

Claim:
An asynchronous data segmentation/transmission method for synchronous Ethernet, comprising the steps of: a) comparing a size (L 2 ) of asynchronous data to be transmitted with a size (L 1 ) of transmission space vacant in an asynchronous frame part of a transmission frame; b) inserting the asynchronous data to be transmitted into the transmission space if the size (L 2 ) of the asynchronous data is equal to or less than the size (L 1 ) of the transmission space; and c), if the size (L 2 ) of the asynchronous data is larger than the size (L 1 ) of the transmission space, segmenting the asynchronous data to fit the size (L 1 ) of the transmission space to insert the segmented asynchronous data thereinto, and inserting remaining asynchronous data (L 2 -L 1 ) into a next transmission frame, wherein, the transmission frame includes a More flag field for indicating a segmentation transmission of the asynchronous data in which the remaining asynchronous data is inserted in the next transmission frame.
