Abstract: A method for identifying VLANs associated with a network includes gathering actual network element configuration data from a plurality of network elements in the network, wherein the actual network element configuration data identifies one or more VLANs that at least some of the plurality of network elements are actually allocated to; correlating the actual network element configuration data with administrative VLAN data; and determining one or more VLANs that are not commonly identified in both the actual network element configuration data and the administrative VLAN data. A system includes a network monitoring system operable to gather actual network element configuration data from a plurality of network elements at one or more logical network sites, wherein the actual network element configuration data identifies one or more VLANs that at least some of the plurality of network elements are actually allocated to; and a VLAN services module operable to correlate the actual network element configuration data with administrative VLAN data, and further operable to determine one or more VLANs that are not commonly identified in both the actual network element configuration data and the administrative VLAN data.

Abstract: 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.

Abstract: 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.
