OG exemplary drawing
 
1. A system, comprising a plurality of hardware network nodes, including a processor with non-transitory computer readable media, for managing network alarms generated by element manager modules in response to corresponding faults/malfunctioning affecting network nodes or links of a telecommunication network, wherein the system stores software that, when executed by the system, causes the system to:
gather network alarms and generate a first set of network alarms comprising at least a subset of the gathered network alarms;
arrange the network alarms of the first set into a network alarm table providing, for each network alarm listed in the network alarm table, data describing the network alarm, wherein the system manages faults/malfunctioning affecting network nodes or links corresponding to the network alarms based on the network alarm table; and
receive an alarm duration prediction request about a predicted duration of a selected network alarm and alarm data regarding the selected network alarm and to generate an alarm duration prediction about a predicted duration of the selected network alarm by processing the alarm data regarding the selected network alarm through a first machine learning algorithm trained with alarm data regarding past network alarms gathered by the system, wherein:
the system generates the at least a subset of the gathered network alarms for generating the first set of network alarms based on the alarm duration predictions,
the selected network alarm is generated in response to faults/malfunctioning affecting a first network node of the telecommunication network, and
the alarm duration prediction is generated by processing, in addition to the alarm data regarding the selected network alarm, alarm data regarding prior network alarms generated in response to foregoing faults/malfunctioning affecting at least one among:
the first network node,
network nodes or links that are logically connected to the first network node, or
network nodes or links that are geographically located close to the first network node.
