Abstract: A method for allocating uplink and downlink bandwidth, includes: receiving, by a primary ONU, a primary PON downlink frame sent by a nested OLT, where the primary PON downlink frame carries a primary ONU uplink bandwidth grant and a secondary ONU uplink bandwidth grant; parsing, by the primary ONU, the primary PON downlink frame to acquire the primary ONU uplink bandwidth grant and the secondary ONU uplink bandwidth grant; and sending, by the primary ONU, a secondary PON downlink frame to a secondary ONU, where the secondary PON downlink frame carries the acquired secondary ONU uplink bandwidth grant. The present disclosure achieves an optimal overall performance for the two stages of PONs by considering general conditions of the two stages of PONs, and meanwhile ensures a maximum available bandwidth for the two stages of PONs during formulation of bandwidth grants.
Abstract translation: 一种用于分配上行链路和下行链路带宽的方法包括：由主ONU接收由嵌套OLT发送的主PON下行链路帧，其中主PON下行链路帧携带主ONU上行链路带宽许可和辅助ONU上行链路带宽授权; 由主ONU解析主PON下行链路帧以获取主ONU上行链路带宽授权和辅助ONU上行链路带宽授权; 并且由主ONU发送次要PON下行链路帧到辅助ONU，其中辅助PON下行链路帧携带获取的辅助ONU上行链路带宽授权。 本公开通过考虑PON的两个阶段的一般条件来实现两个阶段的PON的最佳整体性能，同时在带宽准许期间确保两个阶段的PON的最大可用带宽。
