Abstract: The present invention discloses a dynamic bandwidth assignment method and apparatus on a PON, where the method includes: determining length information of at least one data packet in a cache queue of a T-CONT; determining, according to the length information of the at least one data packet, a total length of at least one GEM frame that is corresponding to the at least one data packet and is obtained when the at least one data packet is separately encapsulated into a GEM frame; and sending a DBRu to an OLT according to the total length of the at least one GEM frame, so that the OLT assigns bandwidth to the T-CONT according to the DBRu. According to the dynamic bandwidth assignment method and apparatus in the embodiments of the present invention, bandwidth of a system can be saved, and overall performance of the system can be improved.

Abstract: Embodiments of the present invention provide an optical network unit ONU registration method, apparatus, and system, to resolve a problem in the prior art that a registration process is cumbersome. The method includes: receiving an uplink optical signal, where the uplink optical signal carries ONU authentication information; sending the optical signal to a corresponding MAC module separately according to a wavelength of uplink light; extracting, by the MAC module, the ONU authentication information, and sending the extracted ONU authentication information to a processor; and receiving, by the processor, the ONU authentication information, and determining whether the ONU authentication information is consistent with ONU authentication information configured by an OLT, where if the ONU authentication information is consistent with the ONU authentication information configured by the OLT, an ONU is registered successfully.
