Embodiment Construction

[0040] Aiming at the problems of complicated ONU remote management process, poor compatibility, and inapplicability to large-scale management scenarios in the related art, the present invention proposes: use the ONU as a private network, use the optical network unit management platform as a public network, and use the OLT as a private network connection The intermediate point of the public network and the address translation and forwarding of the management message based on NAT technology can easily make the remote management of the ONU compatible with various network protocols such as SNMP, HTTP, TELNET, FTP, etc. Management objects are added or deleted; and, with the help of the public network and private network architecture proposed by the present invention, the use of management object address resources can be optimized, a large amount of consumption of address resources can be avoided, and it can be applied to large-scale ONU management, and It is also possible to improve...

Abstract

A management method, apparatus and system of Optical Network Unit(ONU) are disclosed. This method includes that: Optical Line Terminal(OLT) translates the public network address of a management packet transmitted by ONU management platform via a public network connection channel into its corresponding private network address by means of Network Address Translation(NAT) according to the mapping relationship between the public network address and the private network address; OLT transmits the management packet to ONU corresponding to the private network address via a private network connection channel. The usage of the invention can effectively implement the remote management to ONU, avoid transmitting the management packets in a single Operation, Administration and Management(OAM) manner, enable the management packets to utilize multiple protocol formats, effectively improve the extensibility and compatibility of ONU management, save the address resources of the public network and guarantee the security of ONU management within the private network.

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 "fiber to copper retreat", that is, to shorten the length of copper cables in the network, to further extend optical fiber to users, and to build fiber to somewhere (Fiber To Thex) , referred to as FTTx) project gradually uses optical cables to replace the trunk line section, feeder line section, sub-line section, and household line section in the traditional copper cable access network, and evolves the traditional access network with copper cable as the main transmission medium at present. The broadband optical access network with optical fiber as the main transmission medium can finally realize Fiber To The Home (FTTH for short) for users. [0003] During the implementat...
