OPTICAL TRANSPORT NETWORK TRANSMISSION DEVICE AND STUFF CONTROL METHOD THEREOF

摘要

Disclosed is an optical transport network transmission device for transmitting, through an optical transport network, an upper frame in which client data is mapped to the payload of an optical transport unit, wherein the device comprises a Cn calculation means for calculating a Cn value which is a data amount of the client data to be mapped to the payload of the optical transport unit, on the basis of a count value obtained by counting, by a clock of the client data, a period equivalent to the payload of the optical transport unit in the upper frame generated by the clock of the optical transport network side, and information of the Cn value calculated by the Cn calculation means is mapped to the header of the optical transport unit.
