A Decentralized Bandwidth Allocation Scheme for Long-Reach Passive Optical Network


Article Preview

This paper proposes an alternative solution for Long-Reach Ethernet passive optical networks. The proposed scheme enables directly communication between ONUs for the transmission of local traffic and control messages, and each ONU calculates bandwidth allocation independently without participation of OLT to remedy the long propagation delay of LR-PON. This scheme also supports centralized control by OLT to change ONUs’ parameters synchronously. Simulation results show that this scheme can effectively reduce the end-to-end packet delay, while maintaining high throughput in uplink channel.
