Abstract: A device may receive network data associated with a network, and may calculate, based on the network data, key performance indicators (KPIs) for the network. The device may generate a first user interface that depicts one or more of the KPIs, and may receive a selection of a particular KPI from the one or more KPIs displayed by the first user interface. The device may parse a set of rules, utilized to calculate the particular KPI, to generate a parsed set of rules, and may analyze the parsed set of rules to identify particular metrics utilized to calculate the particular KPI. The device may generate a second user interface that depicts one or more timeline views of the particular metrics correlated with the particular KPI, and may provide the second user interface for display.

Abstract: A secure IGP topology or other link state topology can be implemented by a network security unit that runs in a centralized environment on servers separate from a network associated with the IGP topology. The network security unit acquires the topology information, such as by participating in IGP or through border gateway protocol with link state (BGP-LS). The network security unit detects possible network problems, such as indicators of potential network attacks. Once an indicator of a potential network attack is detected, the network security unit identifies the node that is compromised. Once the compromised node is identified, the network security unit can report the node for manual or automated intervention. In some aspects, the network security unit can isolate the compromised node by shutting down links connected to the compromised node.
