摘要
文章提出了一种新的保证服务质量(QoS)的EPON上行动态带宽分配算法,该算法根据区分服务(Diffserv)模型和服务等级协定(SLA)确定光网络单元(ONU)的带宽分配权重,根据数据QoS的不同分配不同的优先权,这样不但确保了各个ONU的带宽分配和QoS,而且可以满足一些高优先级业务的要求。同时,文章还提出了相应的多点控制协议(MPCP)控制消息格式。
A novel QoS-ensured dynamic EPON uplink bandwidth allocation algorithm is proposed, which determines the bandwidth allocation weight among the ONUs according to Diff-serv model and the Service Level Agreement （SLA） and assigns different priorities according to different QoS of the data, thus both ensuring bandwidth allocation to and QoS of each ONU and satisfying the requirements of the high-priority services. In addition, appropriate control message formats in Multi-Point Control Protocol （MPCP） for EPON are presented.
