Embodiment Construction

[0038] The present invention regularly polls the ONU parameter configuration list, adopts a multi-configuration mechanism for individual parameters that fail to be configured, and configures at most 4 times at intervals, which can basically ensure successful parameter configuration. For extreme cases of individual configuration failures, according to the failure handling decision-making mechanism, use methods such as "ignore", "prompt the user to handle manually", and "automatically restart". At the same time, on the network management interface, the present invention adopts eye-catching alarm icons to warn network management personnel to pay attention to configuration failure events. In addition, in the present invention, detailed log records are made for configuration failure events, which is convenient for subsequent analysis.

[0039] The present invention is further described in detail below with specific embodiments and accompanying drawings.

Abstract

The invention provides a reconfiguration processing method for the OLT (optical line terminal) end to ONU (optical network unit) end parameter configuration failure. The method comprises the following steps of: firstly planning the parameter configuration of ONUs; then polling the parameter configuration states of all ONUs once at fixed time intervals; if a parameter of configuration failure exists in one or more ONUs, reconfiguring the parameter of the corresponding ONU; if the reconfiguration is successful, ending the flow; and if the reconfiguration still fails after multiple times, turning to a parameter configuration failure processing flow. The method can solve the problem of individual parameter configuration failure in OLT end to ONU end parameter configuration in time.

Description

technical field [0001] The invention belongs to the field of EPON (Ethernet Passive Optical Network) and relates to the processing technology of parameter configuration between the OLT (Optical Line Terminal) equipment at the local end and the ONU (Optical Network Unit) equipment at the remote end. Background technique [0002] In the EPON system, the OLT end configures and manages the remote ONU through OAM (Operation Administration and Maintenance) frames. In engineering practice, configuration failures often occur due to OAM frame loss or ONU response timeout. [0003] (1) OAM frame loss: [0004] Due to the optical link, the downlink configuration OAM frame or uplink response OAM frame is lost, resulting in configuration failure or configuration process failure; [0005] (2) ONU response timeout: [0006] Due to ONUCPU processing delay or network congestion, the upstream response OAM frame is not returned in time. However, the uplink OAM frame should be returned with...
