Frame Transmitting Apparatus for Strict Synchronization and Frame Transmitting Control Method of It

1. Technical Field of the invention defined in the claims The present invention using the Ethernet will relating to the synchronous Ethernet capable of simultaneously providing an efficient real-time services and non-real-time service. 2. The invention attempts to solve the technical challenges The invention that is the object to provide a frame transmission control bangbeopreul for strict synchronization for controlling whether to output the asynchronous frame transmitted in order to provide a rigid synchronization between each of the transmission cycle in the synchronous Ethernet apparatus. 3. Resolution of the subject matter of the invention, The present invention, in the frame transmission device for a strict synchronization of the transmission cycle of the synchronous Ethernet system, the cycle control unit for providing information about the transmission portion of the transmission cycle; Transport multiplexer for outputting multiplexed in one transmission cycle, the synchronization frame and an asynchronous frame in which the input for transmitting via the frame transmitting device; And using the information about the transmission area of ​​the transmission cycle of the synchronization frame of the size information and the size information, and the cycle control of the asynchronous frame, wherein the synchronization frame to be multiplexed with the total size of the asynchronous frame is the one transmission cycle, without departing in that it comprises a transmission control unit for controlling the transmission group multiplexing. 4. An important use of the invention, The invention yiyongdoem synchronous Ethernet or the like. Synchronization Ethernet, synchronization strict
