System and method for improved distribution of market information
View Patent ↗A data distribution system and method are described herein to improve the distribution of market information to subscribing client devices. Market information updates are provided to subscribing devices over a communication link every time a change in the market occurs. If a bandwidth limitation is reached on the communication link, the preferred embodiments switch to a second mode of transmission such that the market information updates are provided only at predetermined intervals. The preferred embodiment monitors the bandwidth consumption to determine what mode of transmission to apply, and in response, it can dynamically change between modes of transmission. By dynamically adjusting the mode of transmission to comport with the current network bandwidth, the preferred embodiments may provide a network friendly, data intensive, and fast response market information feed.
1. A method for distributing market information, comprising:
distributing market information from an electronic exchange via a communication link according to a mode of communication being dynamically selected between a plurality of modes of transmission for a communication link according to a determined bandwidth usage for the communication link, where the plurality of modes of transmission includes a first mode of transmission including transmitting new market information snapshots for bid orders and ask orders for a tradeable object, and a second mode of transmission for sending market update messages including data retrieved from a data structure having consolidated market data corresponding to the tradeable object.
2. The method of claim 1 where the communication link comprises a network connection.
3. The method of claim 2 , where the network connection comprises an electronic market information source.
4. The method of claim 1 where the first mode of transmission is selected according to high bandwidth usage and the second mode of transmission is selected according to lower bandwidth usage.
5. The method of claim 1 further comprising measuring bandwidth usage, where the selected mode or communication is selected according to the measured bandwidth usage.
6. A system for distributing market information, comprising:
a market information transmitter having a processor, where the market information transmitter transmits market information according to a mode of communication dynamically selected from a plurality of modes of communication according to bandwidth usage of the communication link, the plurality of modes or communication including at least a first mode and a second mode, where the first mode includes transmitting new market information snapshots including a highest bid price for a tradeable object and a lowest ask price for the tradeable object, and the second mode includes sending market update messages including data retrieved from a data structure having consolidated market data corresponding to the tradeable object.
7. The system of claim 6 where the communication link comprises a network connection.
8. The system of claim 7 , where the network connection comprises an electronic market information source.
9. The system of claim 6 further comprising a bandwidth usage monitor configured to measure the bandwidth usage.
10. A system for distribution of market information, comprising:
a market information transmitter having a processor dynamically select a mode of transmitting market information from a plurality of modes according to a bandwidth usage for a communication link for the market information, where the plurality of modes includes a first mode for transmitting market update messages and a second mode for transmitting new market information snapshots having a best bid price and a best ask price, where the first mode is selected according to the bandwidth usage being below a first bandwidth limit, and the second mode of transmission is selected according to the bandwidth usage being above a second bandwidth limit.
11. The system of claim 10 further comprising a bandwidth limit monitor configured to indicate a maximum allowable bandwidth limit for the communication link.
12. The system of claim 11 where the first bandwidth limit is substantially the same as the second bandwidth limit.
13. The system of claim 10 where the first bandwidth limit and the second bandwidth limit are dynamically adjustable.
14. The system of claim 10 further comprising a market information storage buffer for buffering market information.
15. The system of claim 10 where the communication link comprises a network connection.
16. The system of claim 15 , where the network connection comprises an electronic market information source.
17. The system of claim 10 where the communication link comprises a network connection from an electronic market information source to any of a gateway and a client device.
18. The system of claim 10 where the communication link comprises a network connection from a gateway to a client device.
19. The system of claim 10 where the first bandwidth limit and the second bandwidth limit are manually set.
20. The system of claim 10 where the first bandwidth limit and the second bandwidth limit are measured electronically.
