摘要
无源光网络(PON)作为智能光网络(ASON)主流组网技术在融合网络中的应用倍受欢迎。PON组网的关键技术指标在于带宽灵活分配和时延性能。论文借助OPNET仿真平台搭建以太网无源光网络(EPON)模型,在分析、比较传统带宽动态分配算法局限性的基础上提出一种基于多阵列大数据的带宽动态分配优化机制。最后通过仿真数据的比较来验证优化机制下的算法在信道利用率和时延方面的优越性。
As the mainstream network technology of ASON,PON has been widely used in converged networks.The key standards of PON are the bandwidth allocation and flexible delay performance.Based on the OPNET simulation platform to build EPON model,this paper proposes a multi array data of the dynamic bandwidth allocation mechanism,which is through analysis and compared to the limitation of the traditional dynamic bandwidth allocation algorithm.Finally,it is verified that the superiority of the algorithm in the optimization mechanism of channel utilization and delay through the comparison of simulation data.
