Deep Packet Inspection
With all the fuss about Hadopi and controling illicit usage of the broadband connection, this was bound to happen, where there is a new regulation, companies build tools to enforce it. So did Detica with their CView deep packet inspection appliances to measure the level of illegal file-sharing on the network.
The solution yet does not enable tracking of a specific user’s usage an only give metrics on a network-wide level, yet I don’t see why this could not be applied to a specific user.
Virgin Media in UK is the first tester of the solution allegedly to get a measure rather than to act on illegal file-sharing.
