Internet Exchange Point• An Internet exchange point (IX or IXP) is a
physical infrastructure through which Internet service providers (ISPs) exchange Internet traffic between their networks.
• A typical IXP consists of one or more network switches, to which each of the participating ISPs connect.
• The primary purpose of an IXP is to allow networks to interconnect directly, via the exchange, rather than through one or more 3rd party networks.
• The advantages of the direct interconnection are numerous, but the primary reasons are cost, latency, and bandwidth. Traffic passing through an exchange is typically not billed by any party, whereas traffic to an ISP's upstream provider is.
• In many cases, an ISP will both have a direct link to another ISP and accept a route (normally ignored) to the other ISP through the IXP; if the direct link fails, traffic will then start flowing over the IXP. In this way, the IXP acts as a backup link.
National Internet Exchange of India • NIXI is a non-profit Company established in 2003 to
provide neutral Internet Exchange Point services in the country.
• It was established with the Internet Service Providers Association of India (ISPAI) to become the operational meeting point of Internet service providers (ISPs) in India.
• Its main purpose is to facilitate exchange of domestic Internet traffic between the peering ISP members, rather than using servers in the US or elsewhere. This enables more efficient use of international bandwidth, saving foreign exchange. It also improves the Quality of Services for the customers of member ISPs, by avoiding multiple international hops and thus reducing latency.
• NIXI currently has seven operational nodes at the centers in Delhi (Noida), Mumbai (Vashi), Chennai, Kolkata, Bangalore, Hyderabad and Ahmedabad.
