GLink Network Infrastructure Upgrade in Aurora - Q1 2024

The GLink Network Infrastructure Upgrade in Aurora will take place in Q1 2024. This network upgrade consists of:

  • Replacement of the existing end of life (EOL) Juniper switches with new Arista switches which will utilize new customer ports and new CME Group IP addresses
  • Assignment of new GLink SiteIDs and Point-to-Point IPs by CME Group
  • Customers are required to reuse their original Juniper customer source IP addresses
  • Introduction of a new GLink Demarc Cable providing customers with equidistant connectivity to any rack unit (RU) in their cabinet

To ensure stability for our customers prior to launch, CME Group instituted a provisioning freeze for GLinks on the Juniper network effective August 30, 2023. Customers will be able to place orders for new GLinks on the Arista network during the freeze, however these will be provisioned and activated after launch. Juniper GLinks can no longer be ordered.

The expanded Arista network will provide additional capacity to support future growth.  

In addition, the new GLink Demarc Cable will allow customers to optimize their CME Co-Location Licensed Space.

An updated Pending Client System Impact, with general dates and updated technical specifications, is now available. For questions or to discuss available migration options, please contact Global Account Management.

Mandatory Migration - iLink 3 Binary Order Entry Protocol for CGW - January 28, 2024

  • A simple, lightweight, point-to-point session layer protocol using FIX Performance (FIXP)
  • More efficient iLink FIX messaging
  • Standard message size, fixed positions, and fixed length fields
  • A consistent encoding method for order entry and market data

The Client Impact Assessment is available and provides detailed functionality and messaging information.

Based on customer feedback and to better align with iLink 2 CGW, Cancel on Disconnect (COD) will be optional functionality for all iLink 3 CGW sessions. Customers will be able to request COD functionality to be disabled or enabled in:

  • New Release – Now available
  • Production – Now available

Please note that all iLink 3 CGW sessions will be created with COD enabled. Clearing Firm Administrators can disable COD functionality by entering the change request via Firm Admin Dashboard (FADB).

iLink 3 on CGW is currently available in New Release for customer testing.

AutoCert+ certification is required for all client systems using CGWs.

  • Now Available – iLink 3 CGW functionality available in New Release and AutoCert+ certification  
  • January 28, 2024 –  Production launch of iLink 3 on CGW
  • December 31, 2024 – Deadline for customer migration

Drop Copy Impacts - Mandatory iLink 3 Binary Order Entry Protocol for Convenience Gateway - January 28, 2024

On SundayJanuary 28, 2024 (trade date Monday, January 29), CME Group will launch the iLink 3 protocol on existing Convenience Gateways (CGW) for trading futures and options on CME Globex.

Impacts of mandatory iLink 3 Binary Order Entry protocol for Convenience Gateway on Drop Copy Convenience Gateway target sessions.

  • Message encoding: The Drop Copy encapsulated XML Non-Fix (tag 35-MsgType=n) Message payload sent from iLink 3 source sessions will be in ASCII format.
    • Message payload mapping conforming to the iLink 3 formats and encoding will feature deprecated message tags, additional tags and enumerations for order entry, clearing and regulatory compliance messaging specifications.
    • A summary of ASCII encoded tags with their equivalent values in Simple Binary Encoding tags and enumerations is available.
  • Target Session: Current Drop Copy CGW target session users do not need to request new target sessions although upon requesting the mandatory iLink 3 source session, a new target session may be automatically created to accommodate iLink order entry infrastructure load balancing and optimization considerations. Customers are requested to check for new automatically generated Drop Copy CGW target sessions.
  • Parallel period: During the parallel period which runs until December 31, 2024, CME Globex will support Drop Copy target sessions connected to both iLink 2 and iLink 3 CGW sessions. When iLink 2 is decommissioned on December 31, 2024, any Drop Copy target sessions with iLink 2 sessions only will be removed from the platform.
  • AutoCert+ Certification: Certification is not required for existing Drop Copy CGW session users.

Please review Mandatory iLink 3 Binary Order Entry Protocol for CGW for additional details.
