摘要
动态带宽分配是以太网无源光网络(EPON)系统的一个重要研究领域,文章提出一种在EPON系统中保证动态带宽分配公平性的新型算法。该算法计算量适中,同时兼顾了动态带宽分配的效率和公平性。文中通过推导给出了最优算法,并在模拟流量下进行了仿真,通过与已有算法的对比,证明其有很好的性能。
Dynamic Bandwidth Allocation (DBA) is crucial in EPON systems. In this paper, a fairness-guaranteed scheme is introduced for DBA in EPON, which is of moderate computational complexity and guarantees both the efficiency and fairness of DBA. The optimum algorithm is given through deduction and the simulation results from using synthetic traffic confirm its good performance against the existing bandwidth allocation schemes.
