Patent abstract

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 analyses, 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.
