摘要
文章提出了一种基于业务等级协议(SLA)的动态带宽分配算法,该算法根据SLA为光网络单元(ONU)分配带宽权重和相应的优先权,确保了ONU的带宽分配和服务质量,改善了网络的性能,满足了网络业务的QoS要求。最后,通过仿真证明了这种算法的正确性。
This paper proposes a dynamic bandwidth allocation based on SLA in WDM-PON. By allocating bandwidth weight and corresponding priority for ONU, the algorithm insures the bandwidth allocation of ONU and the efficiency of system. It also improves the performance of network and satisfies its QoS demand. Finally, the simulation result shows that the presented algorithm is correct for diverse service level.
