Critical System Updates

CME Globex Performance Enhancements

Starting Sunday, May 3, CME Group implemented an enhancement to futures and options markets on the CME Globex platform. In internal testing, these enhancements reduced latency on CME Globex 5% for futures markets and 10% for options on futures.

There will be no changes to functionality or messaging format with these performance improvements. Good 'Till Cancelled and Good 'Till Date (GTC/GTD) orders will not be impacted.

Removal of RC4 Cipher Suites

CME Group is committed to information security. To deliver the best security and customer experience, we are eliminating support of the RC4-based cipher suites for CME Group web-based applications, APIs, and service in Certification, New Release, and Production environments.

As of this change, customers relying on RC4 cipher suites will no longer have access to these web-based applications, APIs, and services.

Please note: CME Group strongly encourages customers to verify connections so those environments continue to function properly.

RC4 cipher suites support will be removed as follows:

• Production: Saturday, June 6, 2015 at 6:00 a.m. (CT)

Removal of RC4 Cipher Suites
CME Account Manager AutoCert+ Broker to Broker Broker Payment System (BPS) CME Cleared Trades API CME ClearPort API & GUI CME ConfirmHub CME Core CME STP CoLo Portal CME Positions Systems CME DataPoint Deliveries Plus System CME E-Bill Enterprise Reporting Portal (EREP) Exchange Fee System (EFS) FEC, FEC+ and FEC for OTC IRS Firm Admin Dashboard (FADB)	Firm Regulatory Portal FirmSoft Galax-C Admin Give-Up Payment System (GPS) Global Repository Services Membership Portal OR Web Report CME Group Risk Management Tools – Globex Credit Controls (GC2), Risk Management Interface (RMI) Settlements Firm SMART Click EOS Trader Galax-C CME Direct Member Reporting System IRS DMS Registrar Reporting

Customers following CME Group Web Browser Standards should not be impacted by this change. However, if customers connect through a proxy, they should ensure their proxy utilizes one or more of these CME Group supported ciphers:

• TLS_RSA_WITH_AES_256_CBC_SHA256
• TLS_RSA_WITH_AES_256_CBC_SHA
• TLS_RSA_WITH_AES_128_CBC_SHA256
• TLS_RSA_WITH_AES_128_CBC_SHA

The change in Certification and New Release environments is complete.

Leap Second Impact

CME Group uses Network Time Protocol (NTP) to synchronize time for CME Globex systems to maintain effective time accuracy. On Tuesday, June 30 (trade date Wednesday, July 1), a positive leap second will be added after 18:59:59 Central Time (CT).  A leap second is a one-second adjustment that is added to Coordinated Universal Time (UTC) to account for variability of the earth’s rotation.

To facilitate the Leap Second change and prevent any issues on CME Globex systems, all CME Globex products will have a delayed open at 19:45 Central Time (CT), 19:30 CT Pre-open, on Tuesday, June 30 ( trade date Wednesday, July 1). If a CME Globex product’s regularly scheduled open is post 19:45 CT, then that product will open regularly as scheduled.

During a leap second insertion, a UTC timestamp field will read:

20150630-23:59:59 (18:59:59 CT)
*20150630-23:59:59 (18:59:59 CT)
20150701-00:00:00 (19:00:00 CT)

CME Group systems will not send 23:59:60 timestamp, but will repeat the 23:59:59 timestamps twice.

*Please note: A timestamp of 00:00:00 will be disseminated before reverting back to 23:59:59 timestamp.

If the client's system submits an iLink message to CME Globex with the 23:59:60 timestamp, the message will be rejected with Session Level Reject message (tag 35-MSGType=3) with tag 58-Text= SendingTime(52) tag is not formatted properly: 20150630-23:59:60.000.

For more information, a Frequently Asked Questions (FAQ) guide is now available.

MDP 3.0 Migration Schedule

On Sunday, December 7, 2014, CME Group completed the launch of Market Data Platform (MDP) 3.0, a low latency and direct data access solution designed to improve customers' ability to process and act on real-time price information.

Currently, both FIX/FAST and MDP 3.0 are considered to be "Feeds of Record." In case of market data failures, markets may be halted for either FIX/FAST or MDP 3.0 issues. CME Group will review each event individually to determine the best response.

In September 2015, MDP 3.0 will become the sole "Feed of Record" and markets will be halted for MDP 3.0 issues only. After this date, markets will not be halted for only FIX/FAST issues.

CME Group recommends all customers certify for and migrate to MDP 3.0 by September 2015 as the legacy FIX FAST feed will be eliminated in October 2015.

Important Dates
MDP 3.0 Sole Feed of Record – All Channels	September 2015
All FIX/FAST Channels Decommissioned	October 2015

Please Note: There will be no surcharges assessed to customers due to the extended decommission window.

The schedule for implementation of the MDP 3.0 format for the Order Routing Partner Exchanges, BM&FBOVESPA and MexDer (Mercado Mexicano de Derivados) is as follows:

Environment	BVMF	MexDer
New Release	July 2015	August 2015
AutoCert+ Test Suite Available	August 2015	September 2015
Production Parallel	August 2015	September 2015

Please Note: AutoCert+ Certification of the MDP 3.0 and Order Routing Partner Exchange (BVMF and MexDer) Test Suites are mandatory prior to receiving Market Data for each Order Routing Partner Exchange.

TAS Pre-Validation

Currently, order entry will be permitted in TAS (Trade at Settlement) markets as soon as the Pre-Open state message is published, regardless of whether it is received first via the FIX/FAST or MDP 3.0 feeds. As of the MDP 3.0 Feed of Record date, only the publishing of the MDP 3.0 Pre-Open state message will be valid for the start of the TAS market and TAS orders can be entered. The CME Group Market Regulation rules for TAS Transactions can be found here.

Customer systems receiving market data via CME Globex must complete mandatory certification via AutoCert+. The functional and message specifications provide detailed information.

Please contact your Global Account Manager with any questions or concerns in the U.S. at +1 312 634 8700, in Europe at +44 203 379 3754 or in Asia at +65 6593 5505 for additional information.

Drop Copy 4.0 Implementation

In Q3 2015, CME Group will introduce a new Drop Copy implementation to provide further consistency across iLink and Drop Copy. The new Drop Copy 4.0 implementation will have both functional and messaging changes.

The new Drop Copy 4.0 implementation will include:

• Harmonized customer experience between iLink and Drop Copy
• New message format with encapsulated message type.
• New supported FIX tags on Drop Copy messages - inbound and outbound
• Harmonized resend behavior (elimination of Application Resend functionality)
• Sequencing by market segment (see: New iLink Architecture client impact assessment)
• Robust fault tolerance

An updated version of the client impact assessment is now available. The updates include additional details regarding functionality and messaging in the Drop Copy 4.0 Overview section.

The existing implementation of Drop Copy will be phased out on a date to be published in the CME Globex Notices. All customers leveraging the Drop Copy service must be certified for Drop Copy 4.0 by that date.

With the new implementation, the Drop Copy service will have a new session model where customers will have access to two types of target sessions:

• Drop Copy Convenience Gateway (CGW) target session - consumers manage sequence streams from Convenience Gateway iLink source sessions across all market segments.
• Drop Copy Market Segment Gateway target session - consumers manage sequence streams from Market Segment Gateway iLink source sessions per unique market segment; with the possibility of having the same sequence numbers from multiple market segments.

To facilitate migration to the new Drop Copy service, CME Group will support a parallel feed. Traffic from Convenience Gateway source sessions will be available via their current Drop Copy IPs and ports and via the new Drop Copy 4.0 IPs and ports. Certification is required for production access to Drop Copy 4.0. Please coordinate your migration with your CME Group Account Manager.

Upon completion of the Drop Copy 4.0 certification, customers can request Drop Copy CGW and/or Drop Copy MSGW target sessions.

Certification and New Release Drop Copy sessions will be re-issued by your to Global Account Manager upon customer request.

Drop Copy 4.0 is available in New Release for customer testing. A new Drop Copy 4.0 certification suite is available in AutoCert+. Customer systems leveraging the Drop Copy service must complete this mandatory certification.

For more information, a Frequently Asked Questions (FAQ) guide is now available.

Please contact your Global Account Manager with any questions or concerns in the U.S. at +1 312 634 8700, in Europe at +44 203 379 3754 or in Asia at +65 6593 5505 for additional information.

New iLink Architecture

In Q4 2015, CME Group will launch Phase 2 of the new iLink Architecture, which will implement Market Segment Gateways throughout the iLink infrastructure, to provide:

• FIFO ordered message handling per market segment, and
• Elimination of variability associated with multiple sessions across multiple gateways.

All customers are encouraged to review the new iLink Architecture Client Impact Assessment.

The Phase 2 launch will allow customers to access the Market Segment Gateways directly and introduce a new session ID model, messaging and functionality changes. Customers may choose to access CME Globex markets through the MSGWs or the current Convenience Gateways (CGWs), which will continue to be supported and will route through the MSGWs.

Phase 2 will be launched over several weekends. Prior to each launch weekend, CME Group will conduct a mock trading session. MSGWs is available in New Release for customer testing. A new MSGW certification suite will be available in AutoCert+ in Summer 2015. More specific information about the MSGW certification suite and production launch schedules will be published in the CME Globex Notices. Customer systems who want to connect directly to the MSGW must complete this mandatory certification.

Details on the new iLink Architecture roadmap can be found online. For an overview of the new iLink architecture, please review the iLink Architecture webinar.

Please contact your Global Account Manager with any questions or concerns in the U.S. at +1 312 634 8700, in Europe at +44 203 379 3754 or in Asia at +65 6593 5505 for additional information.

New iLink Failover Process

In Q3 2015, CME Group will introduce a new iLink failover process to improve customers’ ability to recover from a CME Globex component failure.

When a CME Globex component fails over from the primary to backup instance, customer iLink messages will be rejected with Session Level Reject (tag 35=3) messages including tag 58=Technical Error - Market Segment: <MarketSegmentID> is not available at this time. After the backup instance is up, order entry will be allowed again.

Currently, messages sent during failover are not guaranteed to be acknowledged by CME Globex. This new iLink Failover Process change will affect all iLink sessions.

Detailed information including this failover behavior change is now available online.

The new iLink failover process currently available for customer testing in New Release.

Further details on the launch schedule will be published in future CME Globex Notices.

iLink Session ID Policy and Operational Guidelines

As a result of the upcoming iLink Architecture with Market Segment Gateways, CME Group plans to introduce a new policy for the distribution and management of iLink session IDs as explained in the iLink Session ID Policy and Operational Guidelines.

Please refer to the CME Globex Notices for more information about MSGW functionality and when the new policy for iLink session IDs will take effect.

To ease and ensure a successful migration to the revised iLink Session Policy, clearing and executing firms are encouraged to contact their Global Account Manager with any questions.
