Abstract:
1. A method for carrying synchronization, comprising: inserting a first timing marker via a symbol in a line encoding scheme associated with a signal comprising Optical Transport Network (OTN) carrying an Ethernet stream, wherein both OTN and the Ethernet stream are asynchronous, wherein the first timing marker points to a second timing marker, wherein the first timing marker is configured to subdivide the Ethernet stream into fixed flits utilized for frame decomposition of the Ethernet stream for one or more clients, and wherein the fixed flits are collectively multiplexed to a higher rate in the Ethernet stream; transmitting the signal with the first timing marker in the Ethernet stream within a payload of an OTN frame to a downstream node; and establishing a timing reference based upon the first timing marker by extracting the first timing marker and the second timing marker from the payload.
