CME Market Data Platform Channel Changes In response to reported customer VPN performance issues in the CME New Release and Certification environments, CME is making the following changes to the CME Market Data Platform. These changes will be effective end of day June 19 in Certification and end of day June 20 in New Release. Customers may require network configuration changes. The new multicast addresses are available online in the Certification Channel Definitions and New Release Channel Definitions. The ITC2.1 format channels on the CME Market Data Platform (3, 4, 5 and 6) will each have a new, dedicated multicast address. These channels are currently unavailable until end of day June 19 in Certification and June 20 in New Release. Please note: CME strongly recommends customers connected to the Certification and New Release environments via VPN join only one ITC2.1 channel at a time to avoid exceeding their VPN bandwidth. The RLC production feeds in the Certification environment will be unavailable for VPN customers since they exceed VPN bandwidth. The Instrument Creation (MO (m-oh)) Replay channels (1 and 16) will each be assigned a new, dedicated multicast address. Currently both channels are on the same multicast. With this change, customers can join each channel separately via their network configuration. If you have any questions, please contact CSET at 312.930.2322. CME now also offers higher-bandwidth connectivity options. Please contact your CME Globex Account Manager at 312.634.8700, or in Europe at 44.207.796.7100 to establish certification connectivity. ©2007 Chicago Mercantile Exchange Inc (CME).
