Abstract
Remediation of network devices that are failing is accomplished using a Shared Failure Domain (SFD) database that provides neighboring device/link information to remediation tools. SFD refers to a group of objects (links/devices) that share a same failure model. A state change of one or multiple of the objects results in a corresponding action on other devices linked together through the SFD. Moreover, the SFD data is available in a central repository and software tools consult the central repository for failure domain data before taking remedial actions. SFD data is generated using configuration generation and device state. Software tools lookup SFD data during operational events (device/link down) and take appropriate actions on the neighboring devices.
