摘要： Disclosed is a method, system, and OLTs for OLT state transition in a dual-parented PON protection system. The dual-parented PON protection system includes a primary OLT and a secondary OLT, configuration information of an ONU having been synchronized on both OLTs, wherein when the secondary OLT fails to detect its communication with the primary OLT and an optical signal from the ONU in the second given time window, the secondary OLT switches to active. Examples of the disclosure render the PON system highly serviceable, more robust, more reliable, and more resilient; besides, the service interruption time may be stabilized to 50 milliseconds or below.

摘要： Disclosed is a mechanism for implementing link state flooding reduction (LSFR) in an Interior Gateway Protocol (IGP) network. The mechanism includes receiving data indicating connectivity of a plurality of nodes in the network. A flooding topology is built based on the connectivity. This includes selecting one of the nodes as a root node, and building a tree of links connecting the root node to the nodes in the network. The flooding topology is stored in a memory. The flooding topology may not be to the remaining nodes in the network. Link state messages may then be flooded over the flooding topology.

摘要： Embodiments of this application provide an optical line terminal, an optical network unit, and an optical communications system, to support an operator to reuse an FTTH ODN to quickly expand and deploy a new service, thereby implementing full-service access on an access network. The optical communications system includes a first optical line terminal OLT, a plurality of first optical network units ONUs, and an ODN connecting the first OLT and the first ONUs. In a downlink direction, the first OLT is configured to convert received downlink data packets of M1 paths into one downlink optical signal whose wavelength is λ0, and the first ONU is configured to receive the downlink optical signal, and output a target user data packet after processing the downlink optical signal. In an uplink direction, the first ONU is configured to convert received uplink data packets into an uplink optical signal whose wavelength is λi, and the first OLT is configured to receive a plurality of uplink optical signals of different wavelengths, and output user data packets of a corresponding quantity of paths after processing.

摘要： This application provides a port detection method, an optical network device, and a passive optical network system, to quickly and accurately detect a port connected to an ONU, and improve efficiency of determining the port connected to the ONU. The method includes: an optical line terminal (OLT) sends optical signals corresponding to all of N wavelengths to at least one optical network unit (ONU), where the N wavelengths are different from each other, and N is a positive integer; the OLT receives optical power values that are of the optical signals corresponding to all of the N wavelengths and that are sent by a first ONU, where the first ONU is any one of the at least one ONU; and the OLT determines, bases on the optical power values of the optical signals corresponding to all of the N wavelengths, information about an optical splitter port corresponding to the first ONU.
