Dynamic bandwidth management based on classification of traffic in software-defined WDM-TDM PON architecture

摘要

Passive Optical Network (PON) is the most promising technology in optical access network, and the effective and reasonable upstream dynamic bandwidth allocation (DBA) is the key. This paper proposes a new software defined WDM-TDM PON frame that enable more users to share a single high-capacity fiber access as well as introduce a flexible DBA module to replace the hardware-configured DBA module. The simulation result shows that the delay is reduced up to 23% and the software-defined PON can meet the different priority traffic of QoS in comparison with traditional PON.
