Explain The Qos In Epon?

1.	Explain The Qos In Epon?
Answer» Many PON applications require high QOS (e.g. IPTV). EPON leaves QoS to higher LAYERS − VLAN tags P bits or DiffServ DSCP In addition, there is a crucial DIFFERENCE between LLID and Port-ID − There is always 1 LLID per ONU There is 1 Port-ID per input port - there may be many per ONU This makes port-based QoS simple to implement at PON layer Many PON applications require high QoS (e.g. IPTV). EPON leaves QoS to higher layers −
