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

No
Yes
Pick up look back length L
packets in the queue
Is any AllOutPacket in L packets?
Check corresponding
VOQi of all non-scheduled TLi
Schedule the packet to TLi to send

Find the longest VOQj in record
Yes
No
Have all packets in whole Queues already been
scheduled?
No
Yes
Collect the AllOutpackets we
found
Is LVOQi empty?
No
Do corresponding TLi of all non-empty VOQi
be scheduled? YesNo

Packet Definition Unicast Packet
Just has one destination Multicast Packet
Single PON Packet More than one destination, and all destinations at
the same AWG output port Multi PON Packet
More than one destination, and destinations at different AWG output port
General Packet Single PON Packet
Cause of receive collision Multi PON Packet
Cause of receive collision or destinations at different AWG output
Original Packet Destination frame without any modify
