VoIP and Streaming are protocols/applications more and more used on the Internet in the terrestrial network. Indeed 40% of the Internet’s traffic in the USA corresponds to the giant of the legal streaming Netflix. In addition to that, according to an OECD’s report, the streaming represents 90% of the Internet’s traffic in 2014.
