Method for automatic synchronization of user device version in Ethernet passive optical network system

Abstract

The invention proposes a method for automatically synchronizing version of an optic network unit in an Ethernet passive optical network. The method comes out to solve a problem that the optic network unit can not be automatically updated in the prior art and includes the following steps: 1. upgrading files required for the optic network unit are stored in an optic line terminal; 2. after the optic network unit is started up, current version information is reported; and 3. the optic line terminal compares the version information of the optic network unit with the version information of the upgrade files corresponding to the optic network unit in the step 1 after receiving the version information of the optic network unit; and if the version information of the optic network unit is the same with the version information of the upgrade files, the steps are terminated, otherwise, the optic network unit executes operation of version update. The invention is mainly applied in the Ethernet passive optical network and can realize automatic update of the ONU, thus lowering maintenance cost.

Description

technical field [0001] The present invention relates to an Ethernet passive optical network system (Ethernet Passive Optical Network, hereinafter referred to as EPON), in particular to a method for automatically synchronizing versions of user end equipment (Optic Network Unit, hereinafter referred to as ONU) in an Ethernet passive optical network system. Background technique [0002] In the EPON system, at least 16 ONUs can be connected to one port of the OLT, and there will be a large number of different types of ONUs in an EPON system at the same time, so the version management, maintenance and control of ONUs is a very important requirement. For EPON systems The scale of application is also a very important function. Although three basic OAM functions are defined in IEEE 802.3-2005, there are no specific regulations for ONU version maintenance and management, online upgrade and other version management functions in a specific network. [0003] Currently, there are two me...

Problems solved by technology

[0016] This method is a step further than the upgrade method of a single ONU, but it also cannot upgrade offline ONUs, so that there will be inconsistent versions of ONUs of the same model in the system, and the problem of version confusion is still faced; and each upgrade Both need to be operated manually, the efficiency is not high, and the upgrade is not complete, especially when the types of ONUs are not completely the same, different types of ONUs also need to be upgraded differently.
