文摘
- •
An OFDMA-PON DBA scheme based on staged optimization algorithms is proposed.
- •
Processes of data mapping and bandwidth arbitration are optimized in this scheme.
- •
A physical layer mapping based dynamic bandwidth allocation algorithm is proposed.
- •
An ONUs requesting based dynamic bandwidth allocation algorithm is proposed.
- •
These two algorithms ensure high network throughput and global quality of service.
