3 What is an IXP ? What is an IXP ? An Internet Exchange Point (IXP) is a network facility that enables the interconnection and exchange of Internet traffic between more than two independent Autonomous Systems. INTERNET International Direct benefit : network International transit Lower Latency IX Domestic Reduce transit cost networks Domestic ISP-A ISP-B peering Increase security ISP-A Customers ISP-B Customers
