Embodiment Construction

[0043] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0044] The ONU remote upgrade self-protection method described in the present invention, when the network management needs to perform remote version upgrade of the ONU, the version upgrade of the ONU is carried out through a number of tags stored in the ONU non-volatile storage device self-protection;

[0045] The mark stored in the ONU non-volatile storage device includes: ONU boot partition mark, ONU has a new upgrade version mark, ONU version upgrade completion mark and ONU upgrade version verification situation mark, these four marks are all stored in the ONU non-volatile memory device. In the volatile storage device, use these four flags to control the ONU remote upgrade and startup process,

[0046] In the non-volatile storage device of the ONU, there are also two partitions for storing the ONU software version. One is the partition where the program i...

Abstract

The invention relates to a self-protecting method for long-distance upgrading of an optical network unit. When a network administrator needs to carry out long-distance edition upgrading on an optical network unit (ONU), the self-protecting of the edition upgrading of the ONU is realized by a plurality of markers stored in non-volatile storage equipment of the ONU, wherein the markers comprise an ONU start-up subarea marker, an ONU new upgrading edition marker, an ONU edition upgrading completion marker and an ONU upgrading edition verification condition marker, and the non-volatile storage equipment of the ONU is divided into two subareas for storing ONU software edition. According to the invention, the reliability of the current operation edition and the upgrading edition of the ONU is effectively guaranteed, the phenomena of random switching of the ONU start-up edition and uncontrollability of ONU engineering application edition caused by misoperation of the network administrator when the ONU is applied to different local equipment are reduced, the ONU upgrading failure problem is repaired remotely, the engineering problem solving timeliness is improved and the robustness of the ONU equipment is enhanced.

Description

technical field [0001] The invention relates to the field of EPON (Ethernet Passive Optical Network, Ethernet Passive Optical Network), in particular to a method for remote upgrading and self-protection of an optical network unit. The optical network unit especially refers to an ONU (Optical Network Unit, optical network unit) on the user side in a 10G EPON system. Background technique [0002] In the context of global informatization, broadband access is developing rapidly. 10G EPON technology has become the most representative and widely applicable next-generation optical access technology in the industry. With the increase of access network users, the switching equipment continues to expand, the access network system is getting larger and larger, and the cost of network operation, maintenance and management is also gradually increasing. higher requirements have been put forward. [0003] At present, there are two main methods for ONU remote upgrade: manual upgrade and ...
