AMS-IX Chicago is a neutral and independent Internet Exchange, distributed across three data centers in Chicago, IL, U.S. This platform is modeled after AMS-IX in Amsterdam, providing a professional, high-quality, non-blocking peering service for all types of IP traffic, from regular IP data to Voice over IP, mobile Internet traffic and video. AMS-IX Chicago is the third deployment of AMS-IX USA Inc., following on from AMS-IX New York and AMS-IX Bay Area. 

AMS-IX USA Inc. is a subsidiary of AMS-IX in Amsterdam. Founded in 1997, AMS-IX is the world’s leading Internet Exchange interconnecting over 700 unique IP networks from around the globe. Additionally, AMS-IX hosts the first mobile peering points worldwide: the Global GPRS Roaming Exchange (GRX), the Mobile Data Exchange (MDX) and the first interconnection of IPX networks (Inter-IPX).

Open-IX initiative 

AMS-IX Chicago is a response to the endorsement process by the Open-IX community. Open-IX is an initiative of a group of Internet networks, content companies and other market parties, such as data centers, that encourages the development of neutral and distributed Internet exchanges and reduce IP interconnect complexity and the associated costs in the US. 

Structure AMS-IX Chicago
To enable the deployment of Internet exchanges in the US, a separate entity in this country was set up. The entity (from here 'USA Inc') is a Delaware incorporated company, very similar to a Dutch BV. The USA Inc. is a wholly-owned subsidiary of AMS-IX BV, whereby the two companies act independently from each other. AMS-IX BV acts solely as a shareholder. No employees or executives working in the Netherlands are placed in the USA Inc. or vice versa. Furthermore, the AMS-IX BV has several operating agreements with the US Inc. that define the operational framework within which the entity can act, as well as license the applicable intellectual property.
