    Abstract: A dynamic bandwidth allocation apparatus of a passive optical network detects guarantee agreement information of each transmission container (T-CONT) queue of at least one optical network unit (ONU) that is connected to the dynamic bandwidth allocation apparatus in order to dynamically allocate a bandwidth is provided. The dynamic bandwidth allocation apparatus sets a queue threshold according to a buffer size of each T-CONT queue of at least one ONU, and calculates a service level agreement (SLA) parameter of at least one ONU using guarantee agreement information and a queue threshold. The dynamic bandwidth allocation apparatus allocates a bandwidth for every frame of each ONU using each SLA parameter of at least one ONU.

    Abstract: A method and apparatus of detecting a rogue optical network unit (ONU) is provided. An optical line terminal (OLT) detects an abnormal upstream transmission to determine a plurality of rogue ONU candidates, and transmits a sleep allow message instructing a transition to a sleep mode to each of the plurality of rogue ONU candidates. The OLT detects the rogue ONU among the plurality of rogue ONU candidates based on upstream transmissions from the plurality of rogue ONU candidates in the sleep mode. Since the detection of the rogue ONU is performed in the sleep mode, the remaining ONUs can transition from the sleep mode to the normal mode after the detection of the rogue ONU is completed, thereby making it possible to rapidly resume upstream communication.

    Abstract translation: 提供了一种检测流氓光网络单元（ONU）的方法和装置。 光线路终端（OLT）检测异常上行传输以确定多个流氓ONU候选，并且向多个流氓ONU候选中的每一个发送指示向休眠模式转换的睡眠允许消息。 OLT根据睡眠模式下来自多个流氓ONU候选的上行传输，在多个流氓ONU候选中检测不流氓ONU。 由于在睡眠模式下执行了流氓ONU的检测，所以在完成了恶意ONU的检测之后，剩余的ONU可以从睡眠模式转换到正常模式，从而可以快速恢复上游通信。
