CME LNet is a client-managed connectivity solution providing access to the CME Globex Platform in Aurora from 350 East Cermak, Chicago, IL. CME LNet service also offers clients connectivity to BrokerTec and EBS US and EU markets located in Secaucus, NJ, and Slough, UK. LNet customers are required to have separate connectivity to access CME Group Futures and Options, BrokerTec, and EBS.   

Customers can connect via CME Group-approved 3rd party vendors who provide a proximity hosting service to all market participants.

There are three CME Group-approved 3rd party vendors. Customers select their vendor based on their individual needs and criteria. Vendors may offer self-managed solutions which allow customers to secure data center space and connectivity with the customer performing maintenance and daily support of the technical environment or fully-managed solutions which include vendor-provided space, connectivity, technical maintenance, and daily services. The customer owns the relationship with the 3rd party vendor and negotiates terms and conditions with the vendor as needed.
