It's action time for the EU!
While its stand on Net Neutrality is not clear (see "EU: Traffic Management, Pay for QoS - are all fine!" - here Vs. "What does the EU Want to Know about Traffic Management?" - here) it decided not to wait any more and look for the use of DPI by leading carriers as a mean to discriminate services.
Jennifer Baker reports to Computerworld that the "The European Union's top antitrust watchdog has carried out unannounced raids on Telefonica, Deutsche Telecom and Orange. The European Commission is concerned that the three companies may have violated E.U. competition rules prohibiting the abuse of a dominant market position, it said Thursday .. The Commission is understood to be looking into network operators' use of deep packet inspection, a technique that allows them to identify the type of content that runs through their networks and allows them to throttle traffic from particularly demanding applications such as video streaming or VoIP calls".
An EU memo explains that "The European Commission can confirm that on 9 July 2013 Commission officials initiated unannounced inspections at the premises of a number of telecommunications companies active in the provision of Internet connectivity in several Member States" (here).
