System and method for improved distribution of market information
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 including:
monitoring, by a first computing device, bandwidth usage of a communication link between the first computing device and a second computing device;
transmitting, by the first computing device, streaming market data for a tradeable object to the second computing device via the communication link, wherein the streaming market data is transmitted according to a selected mode of transmission; and
dynamically selecting, by the first computing device, the selected mode of transmission from a plurality of modes based on the monitored bandwidth usage of the communication link, wherein the selected mode of transmission is selected from a plurality of transmission modes, wherein the plurality of transmission modes includes a first mode of transmission transmitting consolidated market data for the tradeable object at a first time interval when the monitored bandwidth usage does not exceed a bandwidth threshold and a second mode of transmission transmitting consolidated market data for the tradeable object at a second time interval when the monitored bandwidth usage exceeds the bandwidth threshold.
2. The method of claim 1 , further including:
receiving, by the first computing device, market information for the tradeable object;
storing, by the first computing device, the market information in a storage buffer; and
generating, by the first computing device, the consolidated market data for the tradeable object based on the market information stored in the storage buffer.
3. The method of claim 1 , wherein the communication link includes a network connection.
4. The method of claim 1 , wherein the bandwidth threshold is predetermined.
5. The method of claim 1 , wherein the bandwidth threshold is determined dynamically.
6. The method of claim 1 , wherein the second time interval is longer than the first time interval.
7. The method of claim 1 , wherein at least one of the first time interval and the second time interval is predetermined.
8. The method of claim 1 , wherein at least one of the first time interval and the second time interval is dynamically determined.
9. The method of claim 1 , wherein the plurality of transmission modes includes a third mode of transmission transmitting unconsolidated market data for the tradeable object.
10. The method of claim 1 , wherein the plurality of transmission modes includes a third mode of transmission transmitting a market data snapshot for the tradeable object.
11. The method of claim 1 , wherein the first computing device is a market information source.
12. The method of claim 1 , wherein the first computing device is an electronic exchange.
13. The method of claim 1 , wherein the first computing device is a gateway.
14. The method of claim 1 , wherein the second computing device is a gateway.
15. The method of claim 1 , wherein the second computing device is a client device.
