Internet exchange point

  • an internet exchange point (ix or ixp) is the physical infrastructure through which internet service providers (isps) and content delivery networks (cdns) exchange internet traffic between their networks (autonomous systems).[1]

    ixps reduce the portion of an isp's traffic that 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 available through the ixp improves routing efficiency and fault-tolerance. in addition, ixps exhibit the characteristics of what economists call the network effect.[2]
