Patent number: 10951498Abstract: A method for analyzing traffic in a communications network includes sampling data packets at a plurality of network interconnection points, wherein sampling the data packets includes generating a plurality of sampled packet data in one or more standardized formats, converting the sampled packet data from the one or more standardized formats into a neutral format, and aggregating the sampled packet data in the neutral format from the plurality of network interconnection points. A system includes a communications node operable to sample data packets flowing through and generate sample packet data in a specified format, a collector node operable to convert the sampled packet data into a neutral format, the collector node further operable to map IP addresses of the sampled packet data to corresponding prefixes in a routing table; and an aggregator node operable to aggregate neutrally formatted sampled packet data from a plurality of collector nodes.Type: GrantFiled: October 16, 2017Date of Patent: March 16, 2021Assignee: Level 3 Communications, LLCInventors: Raoul Alcala, Niclas Comstedt, Jeff Whitaker
