An IXP (Internet Exchange Point) is an interchange point, a physical infrastructure that allows the various Internet Providers to be connected to each other to exchange the traffic generated by their users and thus create a fundamental part of the Internet.

Internet is a network of networks: each provider needs to be connected to other networks in order to reach all destinations. By connecting to an IXP, it is possible to interconnect with many other networks more reliably, quickly and economically.

In addition, connections are made to ISPs through links to the Internet Exchange of Milan MIX and Rome NaMeX, for an aggregate of 200 Gbit/sec, and links to the Internet Exchange of Turin TOP-IX, Florence TIX and Padua VSIX, for an aggregate of 12 Gbit/sec.

The GARR network interconnects with other networks at the local, national and international level, to facilitate data exchange between the research and education community and its partners. In addition to the usual connections with international research and education networks, it is worth mentioning several peerings with major commercial networks and with the networks managed by local public administrations such as Regions and Municipalities.
