Due to the vast traffic exchange that MIX handles, it is the biggest Internet Exchange in Italy and one of the first in Europe. Internet is a distributed network in which every ISP interconnects its backbone to every other ISP. This distribution is also reflected in Italy, where several networks, differentiated for services offered and for geographic coverage, coexist. This efficient and effective interconnection between different networks is crucial; it impacts both individual backbones and the global network. Here Mix comes into play: born to promote the development of Internet in Italy, and to improve the interconnection between different ISPs operating in our country. Mix is a point of “multiple interconnection” in which the networks of each player (ISP, carrier, content provider, hoster etc…) interconnect themselves to exchange IP traffic (peering) efficiently and with advantageous costs compared to the transit.
