Description
Technical field
The present invention relates to networking technology area, particularly relate to the alert processing method of the optical network unit (OpticalNetworkUnit, ONU) being applied to passive optical-fiber network (PassiveOpticalNetwork, PON) system.
Background technology
Passive optical fiber network system mainly comprises optical line terminal (opticallineterminal, OLT) and ONU.ONU only have through registration, authorize after can normally use.In passive optical fiber network system, after ONU reaches the standard grade, OLT system automatically performs discovery registration process.If find, registration process runs succeeded, and the login state of the upper ONU of OLT is shown as online state, otherwise is shown as offline state.After ONU has registered, can according to the mandate of configuration automatic or manual, licensing process runs succeeded, and the licensing status of the upper ONU of OLT is shown as authorized state, otherwise is shown as unauthorized state.If the ONU off-line of having authorized, then on OLT, the login state of ONU is shown as offline state, and licensing status is still shown as authorized state.
In existing PON system ONU alarm control method, during ONU off-line, the warning information such as communication, equipment of ONU in current alarm information table cannot be removed when receiving the information such as off-line or power down of ONU by warning system, cause the warning information that there is off-line ONU in current alarm information table, and these warning information are insecure.When a certain performance index of ONU exceed set threshold value, ONU produces warning information, and this warning information is reported to optical line terminal (opticallineterminal, OLT).Because the equipment alarm information of some ONU only can report once when this alarm event produces, if before certain warning information of ONU results from certain mandate of ONU, after then this time authorizing, OLT will can not receive this time alarm of this ONU, thus cause imperfect, inaccurate, the insecure problem of the warning information in current alarm information table.
