CME NYDC VPN

To align CME Group regulatory compliance and business continuity planning strategies, CME Group provides a redundant, Out of Region Disaster Recovery (DR) facility for production failover in the event of a large-scale disruption to CME Group Production and DR data centers.

In the event that connectivity to both Chicago area datacenters is lost due to a catastrophic event, customers who subscribe to CME NYDR VPN, can access CME Globex via a CME NYDR VPN connection.

CME NYDR VPN is implemented using a virtual private network (VPN) connection. A VPN is a secure, point-to-point connection between a client and the CME Group out of Region data center. Unlike a direct Wide Area Network (WAN) connection over a costly, leased facility, VPN traffic is carried over the Internet using tunneling technology.  A single router is used to establish connectivity between the client-managed router and the CME Group out of Region Data Center.

Technical Overview

Requirements

Please review the prerequisites below to determine any services, addressing tasks, software, or hardware that customers must have available or complete prior to enabling connectivity for CME NYDR VPN access to the CME production environment.

CME Group does not require customers to use specific consultant vendors. If internal resources are not available, customers are responsible for engaging resources to establish and support connectivity to CME Group.

Internet Requirements

Customers must provide a high-speed connection to the Internet. The connection must meet the following requirements:

  • Internet connection with static public IP address routable on the internet

  • Internet service provider that supports VPN protocols

Software Requirements

The VPN software on your device or service must support the following encryption requirements:

  • PSK for Internet Security Association and Key Management Protocol (ISAKMP)/IKE

  • 3DES/SHA1 encryption or stronger for phase 1

  • AES256/SHA1 encryption or stronger phase 2

Device Requirements

The device prerequisites vary slightly depending on whether existing devices will be leveraged. The following sections describe the three tunneling configuration options that can be used to create the VPN. 

  • Option 1 uses separate units for VPN and GRE tunneling

  • Option 2 uses a single unit for VPN and GRE tunneling

  • Option 3 uses a single unit for VPN tunneling

Option 1: Separate Units for VPN IPSEC and GRE Tunneling

Customers wishing to subscribe to market data that choose to utilize a device or service that does not support GRE tunnel encapsulation, will have to separate the IPsec and GRE termination between 2 endpoints.

Option 2: Combined Units for VPN IPSEC and GRE Tunneling

Customers wishing to subscribe to market data may choose to combine IPSEC and GRE termination into a single device or service.

Option 3: Single Unit for VPN IPSEC only

Customers not wishing to subscribe to market data do not require GRE capability.



CME NYDR VPN Connectivity Procedures

For CME NYDR VPN connectivity, a Cisco IOS configuration is presented as a guide only and must be adapted to other situations as required. There are two options available: With Market Data and Without Market Data.

Testing CME NYDR VPN

Customers will be provided an address to ping in order to verify and validate the health of their VPN IPSEC connectivity when CME Group is not in a DR scenario.
