摘要
Provided is an OTN traffic management method of a traffic management apparatus included in an OTN line card that accepts OTN traffic and transmits the OTN traffic to a multilayer-integrated fabric switch; or accepts traffic, in units of cells, from the multilayer-integrated fabric switch and transmits, to a network, the OTN traffic that the OTN line card generates. The OTN traffic management method includes restoring a received Interlaken packet to an OTN frame; adding an ITMOH that contains information about an ODU payload size to the OTN frame; converting the OTN frame, to which the ITMOH has been added, into to fabric cell by further adding a fabric overhead; and transmitting the fabric cell to the multilayer-integrated fabric switch.
