Shielding alarm method and shielding alarm device of OLT (Optical Line Terminal) system

Abstract

The invention discloses a shielding alarm method of an OLT (Optical Line Terminal) system. The shielding alarm method comprises the following steps: receiving alarm information of a resource object; extracting an alarm source from the alarm information and converting the alarm source into a four-byte integer variable vif; calculating the number Count in the integer variable vif of the alarm source, which is not 0xff from the beginning of the fourth byte; extracting an alarm shielding entry from an alarm shielding table; extracting the alarm source in the alarm shielding entry and converting the alarm source into a four-byte integer variable vif; comparing the first Count bytes of the alarm source vif of the alarm information with the first Count bytes of the alarm source vif of the alarm shielding entry; and shielding the alarm information if the first Count bytes of the alarm source vif of the alarm information are the same to the first Count bytes of the alarm source vif of the alarm shielding entry. By means of the technical scheme provided by the invention, the alarm information satisfying a pre-set alarm shielding rule can be precisely shielded; the technical problem that the alarm shielding stability is influenced due to the fact that the current OLT system is incapable of judging whether to shield the alarm information generated by resource objects having an inclusion relationship can be solved; and the alarm information processing burden of the system is lightened.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a method and device for shielding an alarm in an OLT system. Background technique [0002] The OLT (Optical Line Terminal, Optical Line Terminal) system feeds back system failures or abnormalities to the system administrator in a timely manner through alarms, and the system administrator can control the operating status of the system hardware and software through the alarm information. However, in practical applications, there will be a large amount of alarm information, some of which are repeated frequently or can be ignored, resulting in the truly important alarm information being overwhelmed and ignored, and the massive alarm information also causes great damage to the system. The pressure affects the stability of the normal operation of the system. For these invalid or negligible alarm information, the system administrator selectively filters the alarm informat...

Problems solved by technology

For example, when the configuration shielding rule is set to shield all business boards and shield a certain business board at the same time, it is difficult for the existing OLT system to judge that there is an inclusion relationship or even a mutual exclusion relationship between resource objects. Whether to shield the generated alarm information will affect the stability of alarm shielding
