Customers are responsible for establishing connections from their site to each of the CME Globex Hub - Aurora sites.

    • All IP packets destined for CME Group must be sourced from the CME Group-assigned private address space.
    • Should customers decide to place the server behind another network device, they will be responsible for network address translation.

CME Globex Hub Connectivity Procedures

Upon successful validation and site acceptance by CME Group, the customer is responsible for the following procedures:

  • Activating the multicast stream
  • Configuring the customer application on the arbitration server
  • Configuring routers
  • Configuring the rendezvous point’s IP address
  • Configuring a fixed path between each router and corresponding CME data center
  • Validating that the listener server is receiving data from the correct source

Routing Requirements

Customer routers must be capable of using advanced TCP/IP Protocols including BGP and multicast, specifically PIM Sparse Mode.

  • BGP routing must be used on the routers terminating CME Group connections.
  • It is recommended that customers use a routing protocol between their routers to provide automatic failover.
  • All IP packets destined for CME Group must be sourced from CME Group-assigned private address space.
  • Multicast PIM Sparse Mode must be used.


The following restrictions apply to connectivity:

  • No site-to-site connectivity.
  • No direct server connectivity into CME Globex.
  • Terminating the circuit on a Layer 2 device is not allowed.
  • CME Group will not accept traffic sourced from any customer’s public IP space.
