Embodiment 1

[0082] The traditional single ONU registration mainly uses the random competition mechanism to conduct random competition with other ONUs with the OLT, and complete window ranging and registration in sequence according to the competition results. For multiple ONUs in the same optical network terminal, MAC and How to implement ranging and registration between OLTs, there is no relatively clear implementation method at present.

[0083] This embodiment provides a method for registering an optical network unit, which is implemented based on an optical network unit. The optical network unit includes a processing module and several virtual optical network units VONU, and the several virtual optical network units are connected to several users respectively. There is one-to-one correspondence between physical ports and / or user logical ports; the method includes: controlling the registration process of each virtual optical network unit through the coordination of the processing module....

Embodiment 2

[0129] Traditionally, the online and offline trigger mechanism process of SFU and MDU equipment is mainly triggered based on the SFU and MDU switch points, while the online and offline trigger mechanism of multiple ONU MACs in the same optical network terminal device is triggered according to the physical or logical UNI port status , there is currently no clear implementation method.

[0130] The second embodiment of the present embodiment provides a method for managing online and offline of an optical network unit. The method is implemented based on an optical network unit. One-to-one correspondence between physical ports and / or user logical ports; Figure 11 As shown, the method includes:

[0131] Step 1101: Each VONU detects the power supply status of the corresponding user physical port or the activation or deactivation status of the user logical port;

[0132] Step 1102: The VONU triggers the online and offline process of the corresponding VONU according to the detectio...

Embodiment 3

[0144] Traditionally, the power supply methods of SFU and MDU equipment are local power supply, and the ONU MAC, control system, user network interface and other functional modules of the equipment are supplied with power regardless of whether they are in the working state or not. Causes waste of equipment power supply resources. At the same time, there is currently no clear implementation method for the device power supply mechanism that virtualizes multiple ONU MACs in the same optical network terminal device.

[0145] The present application also provides an embodiment of an optical network unit power supply management method, the method is implemented based on an optical network unit, the optical network unit includes a power management module and several virtual optical network units VONU, and the several virtual optical network units One-to-one correspondence with several user physical ports and / or user logical ports; Figure 13 As shown, the method includes:

Abstract

The invention relates to an optical network unit management method and an optical network unit. The optical network unit management method includes the steps of registration, online and offline management, power supply management, multicast, version upgrading and the like. The optical network unit registration method is achieved based on the optical network unit. The optical network unit comprises processing modules and multiple VONUs. The multiple VONUs correspond to multiple user physical ports or user logical ports one to one respectively. The registration process of all the VONUs is controlled through the processing modules in a coordination mode. The multiple VONUs are virtualized in the optical network unit, the VONUs correspond to the user physical ports and / or the user logical ports one to one respectively, and then the problem that the operation, maintenance and power consumption cost pressure of existing optical network unit equipment is large is solved.

Description

technical field [0001] The present invention relates to the communication field, in particular to an optical network unit management method (including registration, online and offline management, power supply management, multicast, version upgrade, etc.) and an optical network unit. Background technique [0002] With the gradual deepening of the current FTTH (Fiber to the Home, fiber-to-the-home) technology, the ability of domestic and foreign telecom operators to provide users with home bandwidth is also gradually improving. direction of development. However, due to the relatively high cost of FTTH access to the home, and the fact that fiber-to-the-home involves drilling holes through the wall, this has led to difficulties in the construction of fiber-to-the-home. At the same time, the return on investment is low and the investment recovery period is too long. Therefore, operators have The old existing copper cables are used, and various more economical copper wires are us...
