一种长距离混合WDM/TDM-PON系统中基于多线程的具有优先权的动态带宽分配算法
ynamic Wavelength, Priority and Bandwidth Assignment (DWPBA) for Long-Reach Hybrid WDM/TDM-PON Based on Multi-thread Scheduling
随着光纤通信技术的发展，光网络的传输距离从标准的20km增加到了100km. 波分复用技术被视为下一代高灵活性、可扩容的光网络的关键技术。其中WDM/TDM-PON是下一代光网络的最佳选择之一。在这篇论文中，基于长距离混合WDM/TDM-PON系统，我们提出了一种有效的基于多线程的动态波长带宽分配算法（DWPBA）。它需要在分开的波长信道上传输控制信息和数据信息。我们对比了传统的DBA算法和DWPBA算法。通过仿真进行了论证，在光纤长度达到100km的时候，可以获得很高的信道利用率和很低的分组延迟。
With the advances in optical technology, the span of the Passive Optical Network (PON) has been increased from the standard 20km to 100km. Wavelength-division multiplexing (WDM) has been recognized as the key technology in the next generation flexible and scalable passive optical network. WDM/time-division multiplexing (TDM)-PON is one of the candidates, which combine the WDM and TDM technology. In this paper, we propose an efficient DWPBA for Long-Reach hybrid WDM/TDM-PON by separating the Data and REPORT messages under multi-thread scheduling. We compare our proposed algorithm with the traditional algorithm, and show its advantages on packet delay. The results demonstrate that the DWPBA algorithm achieves high channel utilization and low packet delay when fiber length increased to 100 km.
