The Proposed Multicast Algorithm All Out Packet

A packet collision free and all destinations at the same AWG output port in the Scheduling Time

Partition A packet with collision or destinations at different

AWG output port in the Scheduling Time Look Back Length

The packet number can selected form Head Of Line(HOL) packet

Pure Look Back First All Out Packet

Emergency and Ratio Look Back Consider output ratio if TTL large enough Collision free destinations number / Total

destinations number

Conclusion Proposed two multicast scheduling

mechanisms for WDM/TDM PON can satisfy different demand PLB ERLB

Proposed three different upgrade mechanisms 16 x 16 AWG based 8 x 8 AWG based

Proposed the WDM/TDM PON architecture under limited wavelength environment TR RA

62

Future Works

Unbalance traffic Upstream issue Combine with WiMAX
