Publication number: 20200244553Abstract: Internet data such as Border Gateway Protocol routing information and traceroute measurements are processed to create realistic predictive models of the paths IP traffic is likely to take between any two points on the Internet, even when direct measurements of the paths is not feasible. The prediction includes three categories: topology (what paths may exist), weighting (which paths are more or less likely to be taken under varying operational circumstances), and performance (latency, loss, jitter, etc. across the predicted paths).Type: ApplicationFiled: April 10, 2020Publication date: July 30, 2020Applicant: Oracle International CorporationInventor: James H.

Patent number: 9838279Abstract: The disclosed methods and systems include collecting routing data from a plurality of network routers, and correlating the routing data across routers and across time to obtain network data. The network data can be streamed to a user in real-time and the user can interactively query the data. In one embodiment, interactive routing analyzes, drill-down, and forensics can be performed using a repository of Border Gateway Protocol (BGP) update traffic. Alarms can be set to detect selected routing problems. In setting the alarms, the message data for each router can be processed in timestamp order. Current message data from each router can be compared with previous message data to determine a condition status. An alarm can be provided when the condition status meets a temporal correlation criterion and/or a spatial correlation criterion.Type: GrantFiled: March 10, 2017Date of Patent: December 5, 2017Assignee: Dynamic Network Services, Inc.Inventors: Andrew T. Ogielski, James H. Cowie, Alin Popescu
