针对正交频分多址无源光网络(OFDMA-PON),提出了一种基于最小成本最大流(MCMF)的上行带宽分配算法,该算法支持区分QoS。我们定义了一个效用函数作为度量来表征ONU对所获得的带宽的满意度。带宽分配问题,然后制定为最大化的加权总效用函数的总和的所有ONU。通过构造流网络图,利用MCMF算法得到最优带宽分配。仿真结果表明,该方案在平均分组延迟、分组丢失率和吞吐量方面都有一定的改善。
This paper presents a minimum cost maximum flow (MCMF) based upstream bandwidth allocation algorithm, which supports differentiated QoS for orthogonal frequency division multiple access passive optical networks (OFDMA-PONs). We define a utility function as the metric to characterize the satisfaction degree of an ONU on the obtained bandwidth. The bandwidth allocation problem is then formulated as maximizing the sum of the weighted total utility functions of all ONUs. By constructing a flow network graph, we obtain the optimized bandwidth allocation using the MCMF algorithm. Simulation results show that the proposed scheme improves the performance in terms of mean packet delay, packet loss ratio and throughput.
