ABSTRACT:
The method for transporting LAN signal in an OTN is provided by embodiments of the present invention includes mapping a LAN signal into an adaptation protocol frame; mapping the adaptation protocol frame into a virtual concatenation group comprising at least one 1 Gbps level Optical Channel Data Unit (ODU); multiplying the 1 Gbps level ODU in the virtual concatenation group into a higher order ODU; mapping the higher order ODU into a higher order Optical Channel Transport Unit (OTU); and outputting the higher order OTU to the OTN. Embodiments of the present invention improve the bandwidth utilization rate while implementing the transparent transporting of the LAN signal in the OTN.
