Upgraded Reuters Market Data System Offers Flexibility and Openness with Enhanced Performance.

LONDON -- Reuters (Nasdaq:RTRSY)(LSE:RTR) today announced the release of version six of its widely used Reuters Market Data System (RMDS). The new version of this low-latency market data platform has been comprehensively enhanced to give better performance and increased flexibility.

A key feature of RMDS 6.0 is a new binary message format, which substantially reduces the size of the market data updates. This increased efficiency will allow RMDS 6.0 to support higher update rates and comfortably manage the rapid growth in real-time update rates in the market.

Reuters has also introduced the Open Message Model (OMM) in this release - a new and open set of data modelling tools, which deals with complex data types. This new message model gives Reuters customers and partners the ability to publish data across their enterprise in a wide variety of formats via the RMDS platform. It is being used by Reuters to build the Reuters Data Feed Direct managed direct exchange feed service with full order book support.

Reuters dedication to backward compatibility will allow customers wanting to take advantage of the new components the ability to roll them out gradually with continued support for legacy applications.

Michael Parlapiano, Global head of Reuters Information Management Solutions, said: "This is a true innovation for Reuters Market Data System. Version six supports lower latency, higher update rates, and new message formats, without sacrificing backward compatibility. The new Open Message Model is a key extension of our commitment to the openness of RMDS and we hope it will generate innovative uses for the platform by the entire community of customers, and partners."
