Method, device and system for managing optical network unit

Abstract

The invention discloses a method, a device and a system for managing an optical network unit. The method comprises the following steps that: an optical line terminal performs network address translation on a public network address of a management message transmitted by an optical network unit management platform through a public network connection channel to acquire a corresponding private network address according to a mapping relation between the public network address and the private network address; and the optical line terminal transmits the management message to the optical network unit corresponding to the private network address through a private network connection channel. Through the invention, remote management of the optical network unit can be effectively realized, and the transmission of the management message in a single operation, administration and management (OAM) mode is avoided, so various protocol formats can be adopted by the management message, the extensibility and the compatibility of management of the optical network unit are effectively improved, the address resource of a public network is saved, and the safety of the management of the optical network unit in a private network can also be guaranteed.

Description

technical field [0001] The present invention relates to the communication field, in particular to a management method, device and system of an optical network unit. Background technique [0002] In recent years, major fixed network operators have announced the implementation of the development strategy of "optical into the copper out", that is, to shorten the length of copper cables in the network, to further extend the optical fiber to users, through the construction of fiber to the somewhere x, referred to as FTTx) project gradually uses optical cables to replace the trunk line segment, feeder line segment, sub-line segment, and household line segment in the traditional copper cable access network, and evolves the traditional access network that currently uses copper cables as the main transmission medium It is a broadband optical access network with optical fiber as the main transmission medium, and finally can realize Fiber To The Home (FTTH for short) for users.
