Method and apparatus for monitoring data routing over a network
First Claim
1. A method for auditing how a network routes a data packet, comprising identifying a data packet of interest, obtaining an expected path that the data packet of interest is expected to follow through the network, using information recorded by devices in the network to observe the path the data packet of interest actually takes through the network, and comparing the observed path to the expected path.

Abstract
Systems and methods, inter alia, verify traffic flow consistency and audit compliance and adherence to routing protocols employed for carrying data over a computer network. To this end, the systems and methods include, in certain embodiments, devices and methods that monitor data flow across a network and select a data packet moving across the network. The devices and methods observe the route of the data packet as it travels across the network and determine from the observed route whether the data packet traversed the network according to an expected route. Deviations from the expected route are flagged and optionally corrective action is taken to remove from the network a device that is failing to comply with the routing protocol.

17. In a network comprising a plurality of devices for facilitating the transmission of data packets, a system for auditing data packet routing processes to identify a non-compliant device, comprising
an auditing system using information recorded by devices in the network for observing a route of a data packet of interest carried over the network, and an isolation system responsive to the auditing system for comparing an observed route of the data packet of interest with an expected route and identifying whether a non-compliant device has passed the data packet of interest in violation of protocol.
