A high performance long-reach passive optical network with a novel excess bandwidth distribution scheme
We propose new cycle-control slot structures and a distributed MAC over LR-PON. The control slot is routed through an (N+1)(N+1) SC to resolve the long propagation problem. The decentralized MAC shows a three-order-of-magnitude improvement in delay performance. The previous Q-DBA (queue-weight-based-DBA) distributes most excess bandwidth to the malicious ONU. The proposed P-DBA (profit-weight-based-DBA) guarantees very low delay performance even when under attack.
