Abstract
Systems and methods of Ethernet link state signaling through a packet fabric with an Ethernet service transported over Optical Transport Network (OTN) utilizing Generic Framing Procedure Framed (GFP-F) mapping include demapping packets received from an OTN container over GFP-F; detecting a condition associated with the Ethernet service; and causing insertion of maintenance signals in OTN overhead based on the condition instead of using GFP-F Client Management Frames (CMF). The GFP-F mapping can be compliant to ITU-T Recommendation G.Sup43 (02/11) clause 6.2.
