GPON service level agreement based dynamic bandwidth assignment protocol

A dynamic bandwidth assignment protocol is proposed that demonstrates impartial and highly efficient bandwidth arrangement for gigabit-capable passive optical networks. In particular the novel algorithm automatically modifies the assigned bandwidth per optical network unit to support quality of service and service level agreement according to maximum network capacity and users´ queuing status. Network simulation results have demonstrated superior mean packet delay performance achieving a tenfold reduction of packet delay at high network load when compared to other dynamic bandwidth assignment algorithms
