Implementing Method of Logical MAC in EPON and Computer Readable Recoding Medium for Performing it

1. Technical Field of the invention defined in the claims The invention will a method for implementing a MAC for the EPON are defined for standard IEEE 802.3ah EFM (Ethernet in the First Mile) using a commercially available IEEE 802.3 MAC. 2. The invention attempts to solve the technical challenges The present invention is a computer-readable recording a program for realizing the logical MAC implementation of the Ethernet passive optical network system for delivering to a higher layer methods, and the method including the LLID information within a frame in order to use the MAC developed for EPON commercial MAC that aims to provide a recording medium. 3. Resolution of the subject matter of the invention, A first step of the present invention, there is provided a method implemented in the MAC (media access control) Ethernet passive optical network system, including the transfer LLID information in the preamble in a physical layer of the Ethernet passive optical network system; In the RS (Reconciliation Sublayer) layer a second step of transmission by configuring the new Ethernet frame that contains the LLID information contained in the preamble to the Ethernet frame to a higher data link layer of the Ethernet passive optical network system; And including a third step of transferring the new Ethernet frame containing the LLID information from the said data link layer. 4. An important use of the invention, The invention yiyongdoem like EPON. EPON, LLID, MAC, FCS, logical MAC emulation
