针对基于波长变换型远端节点（RN）的环树型时分波分复用无源光网络（TWDM PON）接入网方案，提出了最大带宽利用率算法和最小切换次数算法等两种波长与时隙联合带宽分配算法。仿真结果显示了两种算法的有效性，最大带宽利用率算法可有效提高系统带宽利用率；最小切换次数算法可有效延长系统运行寿命，在现有光开关运行次数条件下系统可保证10年以上的有效运行时间。

In this paper, we introduce a wavelength conversion RN-based ring-tree time and wavelength division multiplexing (TWDM) optical access network (OAN). We also propose a maximum bandwidth utilization rate algorithm and minimum tuning time algorithm. The simulation results show the effectiveness of the two algorithms. The maximum bandwidth utilization rate algorithm improves system bandwidth utilization. The minimum tuning time algorithm prolongs the life of the system, ensuring an effective running time of more than 10 years under existing optical switch running times condition.
