Streaming content can be distributed over a network from sources, e.g., auditoriums, conference rooms, etc., to destinations, e.g., offices, other conference rooms, etc. There is a need to ensure that such a network, e.g., a corporate network, transport a content stream originating from a certain source provides it to the intended destination and only that destination. This verification needs to be performed without accessing the content of the stream itself. This disclosure describes techniques that form a signature of a content stream based on variations in its time series, e.g., by measuring bandwidth values of a certain number of frames. Signatures are obtained at source and destination. If the signatures match, connectivity is confirmed.
