The growth of the internet economy is driven by the innovations in information and communication technology (ICT) sector, and ICT companies play a leading role among research and development running companies (R & D). In the private sphere, the interactive Web 2.0 services, social networks and streaming technology (eg radio streams, video streams, such as YouTube, video on demand, or other data streams such as online games, etc.) are particularly growing in popularity. The annual report on "Cisco Visual Networking Index (VNI) Forecast and Methodology, 2008 - 2013" [3] predicts an increase in global IP data traffic by five times up to 56 exabytes of bandwidth a month. This growth represents a continuing increase in demand for bandwidth equivalent of 40 % annually starting in 2008, about nine exabytes/month (an Exabyte/EB are 1,000 petabytes/PB 1 PB are 1,000 terabytes/GB). For Germany, the Cisco VNI Forecast predicts a rise of about 0.5 exabytes/month in 2008 (home users : 0.35 exabytes) to over 2.5 exabytes/month in 2013 (home users : 1.5 exabytes). In Western Europe, the IP traffic in four years will generally rise up to 12.5 exabytes/month, which is just behind North America with 13 exabytes.
