Abstract: In various embodiments, techniques are provided for creating visualizations of network traffic. Such disclosed techniques may be incorporated by or implemented by one or more computing devices, computer systems, embedded systems, application-specific circuitry, or the like, that generate visualizations of network traffic. Network traffic information may be obtained in response to monitoring network traffic associated with a communications network. The network traffic information may include a variety of detailed or summary analysis of network traffic. In general, network traffic may summarized according to applications associated with network traffic. Hierarchies developed based on relationships between application categories, the applications themselves, and users or groups associated with the applications may be used to develop one or more of a variety of visual representations of the network traffic information.
