Abstract: Novel solutions for monitoring and analyzing networks in terms of the volatility of various devices. Some solutions consider a weighted set of metrics in determining such volatility. Evaluation of devices against peers in view of these factors can produce insight about network conditions.

Abstract: Methods, systems, and computer-readable storage mediums for policy-based testing of computer networks may involve identifying a set of network nodes within a network, and iteratively filtering the set of network nodes in accordance with a testing policy comprising at least one policy rule. Iteratively filtering may include, in an initial iteration, filtering out network nodes that are endpoints of the network from the set of network nodes. Iteratively filtering may further include, for each subsequent iteration, determining a filter criteria from one or more of the policy rules, and filtering out network nodes from the set of network nodes produced by the immediately previous iteration based on the filter criteria. The policy-based testing further comprises invoking a network test scheme that is compliant with the testing policy and is limited to execution against the set of network nodes produced by the iterative filtering.
