Claim:
1. A method for analyzing a content delivery network, comprising: obtaining a plurality of network traffic flows corresponding to a plurality of user nodes accessing contents from a plurality of servers of the content delivery network, wherein the content delivery network comprises a plurality of server groups each comprising a portion of the plurality of servers; extracting, by a computer processor and from the plurality of network traffic flows, a timing attribute from each network traffic flow associated with a server of the plurality of servers, wherein the timing attribute is aggregated into a timing attribute dataset of the server based on all network traffic flows associated with the server in the plurality of network traffic flows; generating, by the computer processor and based on a pre-determined statistical algorithm, a statistical measure of the timing attribute dataset as a portion of a feature vector representing the server, wherein the feature vector is aggregated into a plurality of feature vectors representing the plurality of servers; analyzing, by the computer processor and based on a pre-determined clustering algorithm, the plurality of feature vectors to generate a plurality of clusters; and generating, based on the plurality of clusters, a representation of the plurality of server groups.
