Problems solved by technology

[0004] In the above method, when the network management system software implements monitoring, the OLT device is required to actively send an acquisition request to the ONU device, and then obtain the forwarding performance parameters and configuration information of the ONU device. When the number of ONU devices in the EPON network reaches a certain number, the network management software system It is necessary to obtain the forwarding performance parameters and configuration information of each ONU in real time, so that a large number of query messages are generated for each ONU device in a short period of time, which affects the efficiency of the ONU device, and a large number of query messages need to occupy the EPON chain The transmission bandwidth of the road affects the user experience

Embodiment 1

[0043] The method of the present application is mainly applied to the Ethernet passive optical network EPON system. The Ethernet passive optical network is a passive optical network (Passive Optical Network, PON) technology based on Ethernet, and adopts a point-to-multipoint network topology structure. Through passive optical fiber transmission, various services are provided on Ethernet.

[0044] The Ethernet passive optical network EPON system mainly includes: optical line terminal, network management system and optical network unit. The configuration information and status information between OLT equipment and ONU equipment are realized through the extended Ethernet OAM protocol.

[0045] refer to figure 1 , which shows a flow chart of a method for managing an optical network unit ONU according to Embodiment 1 of the present application. Wherein, the method is applied to an Ethernet passive optical network EPON system, and the method specifically includes:

[0046] Step 10...

Embodiment 2

[0061] refer to figure 2 , which shows a flowchart of a method for managing an optical network unit ONU according to Embodiment 2 of the present application, specifically including:

[0062] Step 201: The optical network unit ONU receives the event customization message of the Ethernet OAM extension protocol sent by the optical line terminal OLT.

[0063] The event customization message is a message customized by the optical line terminal based on user requirements.

[0064] In order to allow the OLT to send event customization messages to the ONU, it is necessary to further optimize the existing Ethernet OAM extension protocol, that is, to add a new field to represent user customization items in the Ethernet OAM extension protocol.

[0065] The user's customization items include: the event notification information (Notify message) initiated by the OLT and the message type actively reported by the ONU. The ONU parses the event notification information and obtains the configu...

Embodiment 3

[0084] refer to Figure 5 , which shows a structural diagram of a device managed by an optical network unit ONU described in Embodiment 3 of the present application, the device is applied to an optical network unit ONU of an Ethernet passive optical network EPON system, and may specifically include:

[0085] The receiving module 501 is configured to receive the event customization message sent by the optical line terminal OLT.

[0086] The monitoring module 502 is configured to perform local monitoring according to the custom message of the event.

[0087] The reporting module 503 is configured to, when it is monitored that the information related to the event customization message has changed, the ONU actively reports the changed information to the OLT, so that the OLT can manage the ONU.

[0088] In the embodiment of the present invention, the OLT sends an event customization message to the ONU, so that the optical network unit performs local monitoring according to the eve...

Abstract

The invention provides an optical network unit ONU management method and an optical network unit ONU management device, which are applied to an Ethernet passive optical network EPON system. The optical network unit ONU management method comprises the steps that: an optical network unit ONU receives an event customization message sent by an optical line terminal OLT; the optical network unit ONU performs local monitoring according to the event customization message; and the optical network unit ONU reports changed information to the OLT when the optical network unit ONU monitors that the information relevant to the event customization message has changed, so that the OLT manages the optical network unit ONU.

Description

technical field [0001] The present application relates to communication technology, in particular to a method, device and system for managing an optical network unit (ONU). Background technique [0002] Ethernet Passive Optical Network (EPON) mainly includes optical line terminal (optical line terminal, OLT) and optical network unit (Optical Network Unit, ONU), configuration information and The status information is realized by extending the Ethernet OAM protocol. [0003] In an EPON network, the network management software system needs to monitor each ONU in real time and read the forwarding performance parameters and configuration information of each ONU in a timely manner. Therefore, it is necessary to periodically trigger query messages to obtain the forwarding performance parameters and configuration information of the ONUs, and query messages Realized by Ethernet OAM extended protocol message, wherein, the extended Ethernet OAM protocol message includes read operation...
