Explain The Epon Frame Format?

1.	Explain The Epon Frame Format?
Answer» EPON operation is BASED on the Ethernet MAC and EPON frames (based on GbE frames), but extensions are needed : MultiPoint Control Protocol PDUs :This is the control protocol IMPLEMENTING the required logic. Point-to-point emulation (reconciliation):This MAKES the EPON looks LIKE a point-to-point link and EPON MACs have some special constraints. Instead of CSMA/CD, they transmit when granted. Time through MAC stack must be constant (± 16 bit durations). Accurate local time must be maintained.
