Abstract: Disclosed is method for scheduling a data message in a Passive Optical Network (PON) and Ethernet Over Cable (EOC) networking, which may include: an Optical Coax Unit (OCU) allocating a coaxial side Logical Link Identifier (LLID) for a Coaxial Network Unit (CNU) which accessed the OCU, and acquiring an optical network side LLID allocated for the OCU by an Optical Line Terminal (OLT); and establishing a mapping relationship between the coaxial side LLID and the optical network side LLID, and scheduling a data message of the CNU according to the mapping relationship. Also disclosed are a system for scheduling a data message in a PON and EOC networking and a related device.

Abstract: Techniques for updating configuration of an Optical Network Unit (ONU) in an Ethernet Passive Optical Network (EPON) include receiving a notification that an updated configuration file is available for the ONU, obtaining the updated configuration file, performing a first validation of the updated configuration file for structural errors, determining changes between a current configuration of the ONU and the updated configuration file to identify ONU resources to implement to the changes, performing a second validation about whether the ONU resources to implement the changes are available or not at the ONU and applying the changes to the ONU when it is determined that the ONU resources to implement the changes are available at the ONU.

Abstract: Systems, devices and techniques for automatically configuring a Demarcation device in a communication network based on DOCSIS provisioning over EPON.

Abstract: A DPOE system and a service auto-configuration method and network based on that system are provided, wherein, the DPOE system includes an acquisition unit, an analyzing unit and a configuration unit; the service auto-configuration network includes a DPOE system, a back-office management system and an ONU; the service auto-configuration method based on that system includes: the DPOE system acquiring a configuration file from the back-office management system, wherein the configuration file includes configuration information of the ONU and configuration information of an OLT in the DPOE system; the DPOE system analyzing the configuration file and obtaining the configuration information of the ONU and the configuration information of the OLT; configuring the OLT locally and configuring the ONU via a management channel between the OLT and the ONU. Thus the service can be opened without performing further configuration to the OLT individually after the process of the ONU initialization is completed.

Abstract: A method and system for managing resources in a photoelectric hybrid system are disclosed. The method includes: for a Coaxial Network Unit (CNU) operating in a half-duplex operating mode, an Optical Line Terminal (OLT) managing uplink bandwidth resources of the CNU according to uplink bandwidth information of the CNU and an ONU; and the OLT and an OCU together managing downlink bandwidth resources of the CNU.

Abstract: The disclosure provides a method and system for realizing power saving mechanism management between an Optical Network Unit (ONU) and an Optical Line Terminal (OLT). The method includes: passing power saving information between the ONU and the OLT through an extended Operation Administration and Maintenance (OAM) frame; closing/opening an optical module of the ONU based on the obtained power saving information. With the method of the disclosure, the optical module is closed in time when the optical module of the ONU is not needed, thus reducing power consumption of the ONU, and enabling interaction between the ONU and the OLT to meet the requirement for power saving and emission reduction.

Abstract: Disclosed in the present invention are an alarm processing method and device for a PON system in power-saving mode, for solving the technical problem that the PON system cannot process the alarm or exception message after the ONU enters power-saving state and the management server is misled to deem that the system is abnormal. In the present invention, when the OLT detects the alarm generated for a certain ONU, it acquires the current power-saving working state of the ONU, and if the ONU is currently in power-saving state (such as doze state, i.e. Tx mode), the OLT suppresses, discards or shields the relevant alarm by the ONU currently in power-saving state. By way of the present invention, the alarm processing pressure can be alleviated and the real state of the ONU can be reflected.
