reconciliation sublayer (Fast Ethernet) (RS)
The reconciliation sublayer (RS) and the media independent interface( MII) together form the access to the physical layer( PHY) in the faster Ethernet variants- Fast Ethernet, Gigabit Ethernet and 10 Gigabit Ethernet.
Here, the reconciliation sublayer takes over the logical interface between the MAC layer with the media access method and the Media Independent Interface and converts the primitives from the MAC layer and the Physical Layer Signaling( PLS) into MII signals.
