1. A method comprising steps of:
receiving an Optical Transport Network (OTN) signal;
segmenting the OTN signal into one or more flows of packets having one or more properties including addresses and sequence numbers, such that the OTN signal is encapsulated in the one or more flows of packets; and
transmitting the one or more flows of packets spread over one or more Ethernet links, based on using or adjusting the one or more properties to enable reassembly of the one or more flows of packets back to the OTN signal, wherein the one or more flows of packets are one or more of i) one or more elephant flows and ii) one or more mice flows with specific addresses in a given flow, and, for the one or mice flows, the sequence numbers are greater than 2-bits.
