Embodiment Construction

[0035] In order to make the object, technical solution and advantages of the present invention clearer, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0036] The embodiment of the present invention separates the configuration of the ONU from the physical application of the configuration on the real ONU on the OLT, and separates the existence of the ONU from the activation of the ONU to realize the pre-configuration management of the ONU by the OLT.

[0037] Among them, separating the configuration of the ONU from the physical application of the configuration on the real ONU means that the user can simulate a virtual ONU that is consistent with the physical identity and type of the real ONU through the OLT when the real ON...

Abstract

The invention discloses a method for pre-configuration management of an ONU (optical network unit) by an OLT (optical line terminal). The method includes establishing a virtual ONU, and loading management data structure of the virtual ONU; pre-configuring the virtual ONU and storing pre-configuration information of the virtual ONU; and when a real ONU goes online, issuing the pre-configuration information in batch for the real ONU. The invention further discloses a device for pre-configuration management of the ONU by the OLT. The device comprises an ONU virtual configuration module, an ONU virtual configuration storage module and an ONU remote communication module. Inconvenience in management and maintenance caused by configuration differentiation due to a large number of ONUs in a PON (passive optical network) is overcome by a pre-configuration method. The method and the device are simple to implement and efficient and can be used for all OLT devices.

Description

technical field [0001] The invention relates to the field of optical communication, in particular to a method and a device for configuring and managing a user optical metering network unit by an optical line terminal in an Ethernet passive optical network environment. Background technique [0002] With the continuous development of PON (Passive Optical Network) access technology, higher requirements are placed on the integration and manageability of broadband access equipment. Passive optical network is generally composed of OLT (Optical Line Terminal) on the office side, ONU (Optical Network Unit) on the user side and ODN (Optical Distribution Network) on the user side. It is a single-fiber bidirectional system. Its typical The topology is tree-shaped. In the downstream direction (OLT to ONU), the signal sent by the OLT reaches each ONU through the ODN. In the upstream direction (ONU to OLT), the signal sent by the ONU will only reach the OLT, but will not reach other ONU...
