Abstract
Flexible Ethernet (FlexE) Forward Error Correction (FEC) systems and methods include mapping a first set of calendar slots including Ethernet payload clients to a FlexE Time Division Multiplexing (TDM) structure including a plurality of calendar slots; and mapping a second set of calendar slots including FEC data to the FlexE TDM structure, wherein the first set of calendar slots and the second set of calendar slots fill the FlexE TDM structure. In an exemplary embodiment, an overall Physical (PHY) rate of the FlexE TDM structure is kept constant with a reduction in bandwidth for the Ethernet payload clients based on the second set. In another exemplary embodiment, the overall Physical (PHY) rate of the FlexE TDM structure is increased based on the second set of calendar slots, to support a set rate for the Ethernet payload clients with a reduced number of calendar slots.
