roadband is used (e.g. in many national broad- band strategies for 2020 and beyond) to point to higher bitrates than the existing broad- band worldwide. While existing broadband access (on average) is in the range of Mbit/s per user to tens of Mbit/s per user, ultra-broadband access is targeted at bitrates in the range of several hundreds of Mbit/s per user to Gbit/s per user. However, the defined QoS and QoE refer to current and future broadband and ultra-broadband speeds. The principles of QoS and QoE as well as the QoS framework will not change significantly in the near future; however, they will evolve together with the appearance of new inno- vative services/applications in the global telecommunications/ICT world.
