Abstract
Methods and systems of a disaggregated optical transport network (OTN) switching system that include using plug-in universal (PIU) modules for OTN to Ethernet transceiving and an Ethernet fabric as a switching core are disclosed. An OTN over Ethernet module in each of the PIU modules may enable various OTN functionality to be realized using the Ethernet fabric which may include multiple Ethernet switches. A virtual line card may include a logical aggregation of a kth Ethernet switch sub-port of each of the corresponding Ethernet switch ports of each of the Ethernet switches. A virtual switch fabric may include multiple virtual line cards for the OTN switching system. Each of the virtual line cards may be associated with a virtual address that may correspond to a respective PIU module. The virtual address may include a media access control address associated with the respective PIU module.
