IPACT

ONUs: 8, total bandwidth:1G, OLT-ONU distance: 20 km

The OLT allocate bandwidth for Inter & Intra ONU

Good performance, but it does not support QoS and its centralized

EDDBA

ONUs: 8, total bandwidth: 1G, OLT-ONU distance: 20 km

Each ONU allocate bandwidth for its own through the OLT broadcasted information

Support QoS, but the decision not optimal efficient. Decentralized, but still need the OLT arbitration

IDDBA

ONUs: 8, total bandwidth: 1G, OLT-ONU distance: 20 km

The intelligent agent’s communication system provides efficient sharing information protocol between the ONUs

Support QoS, but the decision is rational using agents and the allocation impact is efficiently optimal. Fully decentralized based on decentralized agent’s machinery. Shows good fairness due to collaborative behavior
