Summary

Recommendation ITU-T G.8112/Y.1371 specifies the interfaces for the multi-protocol label switching transport profile (MPLS-TP) layer network. The interfaces for the MPLS-TP layer network use various server layer networks, like the plesiochronous digital hierarchy (PDH), synchronous digital hierarchy (SDH), optical transport hierarchy (OTH) and the Ethernet media access control (MAC) layer network (ETH).
