Abstract
In APON system
one of the key technologies is to dynamically assign bandwidth among different services and guarantee QoS. This paper designs a APON service scheduling algorithm
which realizes the dynamic bandwidth assignment among different service grades through basic bandwidth assignment and surplus bandwidth re assignment. Furthermore
the result of emulation and field test proves that this scheduling algorithm has good performance and feasiblity.
