Embodiment Construction
[0016] Embodiments of an ONU registration method based on an inquiry mechanism in an Ethernet passive optical network according to the present invention will be described in detail below with reference to the accompanying drawings.
[0017] figure 1 It represents the handshake process of the discovery message defined in the IEEE 802.3ah standard in the prior art. Such as figure 1 As shown, the discovery process is initiated by the OLT, which periodically generates a legal discovery time window to detect offline ONUs. The OLT notifies the ONU of the period of the discovery window by broadcasting a discovery gate message (Discovery GATE). After receiving the discovery strobe message, the off-line ONU waits for the start of the discovery window period, and then sends a registration request message REGISTER_REQ to the OLT during the discovery window period. After receiving the valid REGISTER_REQ, the OLT registers the ONU, allocates and specifies the logical link identifier (LL...
