Abstract

The invention is suitable for any kind of distributed networks having different data rates on different connections and a centralized computer system wherein the data to distribute is created. The central system comprises one or more supersets of data that is to be distributed to client computers by extracting subsets of data from the superset / s of data. Thereafter the subsets of data are distributed to selected groups of clients based on information about the network architecture. In this way an efficient way of distributing data is executed and no duplicated data is distributed. Preferably the subsets are distributed to clients based on a counter performance or a data rate of a client's connection to the central computer system.

Description

FIELD OF THE INVENTION

[0001] The present invention relates to distribution of data in computer systems. In particular it relates to information dissemination in high performance trading systems.BACKGROUND OF THE INVENTION

[0002] Today it is very common that information is sent over computer networks. The amount of information being sent is rapidly increasing due to the advances in technology, making it possible to send and handle more information at higher speed compared to before. Furthermore, new applications demands a higher amount of information compared to before. Even further, the importance of information has open up a new field of business wherein information is sold.

[0003] An example of computer systems wherein information dissemination is one of the most essential parts are electronic trading systems.

[0004] Electronic trading of securities, derivatives, commodities and other financial instruments results in large amount of information which has to be distributed to users that n...

Examples

Embodiment Construction

[0132]In this application some specific terms are used, below follows a description of these.

[0133]MBO—Market By Order—In FIG. 3 this type of message 13 is picturized. This type of message flow contains the order book changes that occur in the order depth for an instrument. Each change will be represented in a message by a delta change. The external applications can use this information to build up their order depth for this order book and maintain a shadow of the real order book. It is possible to say that only order changes that occurs on the top X levels shall be distributed and by doing so the external application will have a copy of the order depth for those levels.

[0134]MBP—Market By Price—This type of message 11 contains information on the price levels that exists in the market with a summary of the total volume on each level. It is possible to say that only the top Y price levels will be distributed.

[0135]A MBO example will be used as support for the description, in order to...
