Embodiment Construction

[0032] The present invention provides a method and system for automatic upgrading of various ONUs in a GPON access system. First, the upgrading files are sorted to form an upgrading file list, and then the main control disk downloads an upgrading file each time according to the order of the upgrading file list. In the internal memory, issue batch upgrade commands and upgrade files to the corresponding line cards, and the line cards complete the upgrade of the corresponding ONUs. After all the line cards receive the upgrade files, the main control disk clears the memory and downloads the next upgrade file. Until the upgrade of all ONUs is completed. Since the main control panel only downloads one upgrade file to the memory at a time, on the basis of limited storage capacity, make full use of the existing ONU manual batch upgrade function, and use the distributed computing capability of the line card to trade time for space. Realize the ONU automatic upgrade method that is not l...

Abstract

The invention discloses a method and a system for multi-ONU (optical network unit) automatic upgrading in a GPON (gigabit-capable passive optical network) access system. The method comprises the following steps: A10, a plurality of upgraded files are sorted to form an upgraded file list; A20, after a master control panel receives an automatic upgrade enabling instruction which is sent by a web master, the master control panel inquires in turn authorized and on-line OUN on each line card, and all on-line ONU hardware and software inversions are obtained; A30, the master control panel downloads a corresponding upgraded file into a memory according to the sequence of the upgraded file list, and sends batch upgrading orders and sends the upgraded files to a or a plurality of corresponding line cards according to the type of the ONU corresponding by the upgraded files, and the corresponding line cards control all ONU which take down from the line cards and are corresponding with the upgrading files to realize upgrading; A40, the master control plane releases the space which stores the upgraded files in the memory. According to the invention, the master control plane only downloads one upgraded file into the memory each time, and the pressure of the system memory is relieved greatly.

Description

technical field [0001] The invention relates to a method for managing ONUs in a PON access network system, in particular to a method and system for automatic upgrading of various ONUs in a GPON access system. Background technique [0002] GPON (Gigabit-Capable Passive Optical Network, GPON) technology is the latest generation broadband passive optical integrated access standard based on the ITU-TG.984.x standard, which has high transmission rate, long transmission distance, high efficiency and scalability Strong, support services with different QOS requirements, strong OAM capability and robustness, high security and other characteristics, it is regarded by most operators as an ideal technology for realizing broadband and comprehensive transformation of access network services. [0003] Similar to the existing PON system, the GPON system is also composed of OLT, ONU, and ODN. ODN (Optical Distributed Network) is composed of optical fiber and passive optical splitter. It con...
