Abstract:

Out-of-profile rate-limited traffic is sampled to provide data for analysis, such as for, but not limited to, identifying a threat condition such as a denial-of-service or other malicious attack, or a non-malicious attack such as an error in configuration. A rate limiter including at least three states is typically used, with one of these states being an out-of-profile sampling state wherein the packet traffic is sampled to identify one or more sampled packets on which analysis can be performed, with defensive action possibly taken in response to the analysis.

Abstract:

Embodiments of the present invention provide improved methods, techniques, and systems to compute relevant and useful information that may be presented to users in an understandable, intuitive, and actionable platform. The interactive platform includes a format and visualization that is capable of presenting data for a wide range of protocols and topologies at various functional layers of the network. The interactive platform provides selectable categories of filters which update the network data and views displayed to the users to aid in the analysis and investigation of potential root causes of problems, rather than merely presenting examples of symptoms. The interactive platform includes a method and visualization that is capable of presenting differences in network behavior at various functional layers of the network.
