Abstract

See full text

In an embodiment, a method monitors a plurality of data streams passing through a router in the connectivity service provider environment, and for each of the data streams, periodically samples packets at the router. The method further generates a stream signature based at least on the payload of the sampled packets. The method further includes, for each generated stream signature, attaching information to the stream signature. Such information may, for example, include time-stamp information for the stream signature, or an identification of the router. The method may further comprise storing the stream signatures corresponding to the data streams in a database. The stored stream signatures may be compared to determine matching stream signatures. Matching signatures may identify data streams that carry identical or similar content.
