Abstract
According to one method for identifying and resolving a silent failure in a telecommunications network, performance data associated with data traffic passing through a network element in the telecommunications network is collected. A determination is made whether the performance data has fallen below a threshold to identify the silent failure at the network element. The silent failure fails to trigger an alarm included on the network element. Responsive to determining that the performance data is below the threshold and thereby identifying the silent failure at the network element, troubleshooting rules may be retrieved. The silent failure is resolved based on the performance data and the troubleshooting rules.
