2.18 Internet exchange point / IXP

Physical infrastructure through which Internet service providers (ISP) exchange Internet traffic between their networks (autonomous systems).

Note:

Internet exchange points (IXP) reduce the traffic portion of an Internet service providers’ (ISP) which must be delivered via their upstream transit providers, thereby reducing the average per-bit delivery cost of their service. Furthermore, the increased number of paths learned through the IXP improves routing efficiency and fault-tolerance.
