Patent number: 11206203Abstract: Embodiments generally disclosed herein include a computer-implemented method for monitoring and correlating network traffic data associated with a primary network that is in communication with a plurality of secondary networks. The method generates a network traffic data set by monitoring network traffic between the primary network and the plurality of secondary networks. The method also determines a mapping of network connectivity by monitoring inter-network routing information between the primary network and the plurality of secondary networks. In addition, the method generates a traffic measurement data set by monitoring network utilization statistics between the primary network and the plurality of secondary networks. With the collected data sets, the method then calculates a relational network mapping between the primary network and the plurality of secondary networks by correlating the network traffic data set, the mapping of network connectivity, and the traffic measurement data set.Type: GrantFiled: March 1, 2021Date of Patent: December 21, 2021Assignee: Level 3 Communications, LLCInventors: John Kane, Joseph Lawrence, Maria Farnon, Rick Nooner, Raoul Alcala, Mark Taylor
