Internet exchange points (IXPs) are a key part of the Internet ecosystem and represent a vital way to increase the affordability and quality of connectivity in local communities.
What Are IXPs?
An Internet Exchange Point (IXP) is simply a physical location where different IP networks meet to exchange local traffic with each other via a switch. They are integral part of the Internet ecosystem.
IXP Models
IXPs fall roughly into five categories: non-profit organization, an association of ISPs, operator-neutral for-profit company, univeristy or gov agency, or an informal association of networks
Physical Infrastructure
IXPs can be located in a number of different locations. Once determined, it is crucial to then identify appropriate power sources , cooling, security, and technical experts to run and manage the IXP.
Business Case
IXPs provide a competitive alternative to routing domestically destined traffic abroad. IXP viability can be calculated for interested ISPs by comparing the cost of IP transit to the cost of domestic peering.
