Abstract: A method includes forming a logical group of network devices from a plurality of network devices based on at least one attribute of the network devices. The method further includes selecting at least one similarity metric for the logical group of network devices. The method also includes determining a value of the similarity metric for each of the network devices of the logical group. The method further includes comparing values of the similarity metric corresponding to each of the network devices of the logical group against a threshold value. The method also includes determining an action to be taken at one or more of the network devices based on the comparison between the values of the similarity metric and the threshold. There may also be multiple interconnected groups, each performing these actions independently and conveying the computed information between each other.
