CME, the world's largest and most diverse financial exchange, announced today that it will begin offering customer firms the opportunity to connect their colocated trading servers to the CME over high-speed fiber optic connections in the fourth quarter of 2006.

The new connection option is called CME Local Network (CME LNet).

"By offering this colocation alternative in response to customers' requests, CME continues its legacy of offering the most innovative technology solutions available. Speed and reliability are two of the most critical components of electronic trading in our business and our technology investments continue to focus on these core components," said CME Managing Director of Products and Services Rick Redding. "We offer electronic trading access to every major asset class. Customers around the globe who are trading electronically depend on the reliability of our platform and access to our products virtually around the clock."

( http://www.digitalrealtytrust.com ), a leading owner and manager of corporate data centers and Internet gateways, will enable customers to directly connect to CME Globex through high performance, high availability fiber links.
