Abstract

System and methods for a connection proxy server are described. According to an example method described herein, a connection proxy server stores subscription, product tables as well as other downloads that are provided to a client terminal during initialization stage as well as later during a trading session. Upon detecting that a connection between the client terminal and a gateway is lost, the connection proxy maintains a communication session created for the client terminal at the gateway and receives data intended for the client terminal. If the connection is re-established between the client terminal and the gateway during a predetermined period of time, the connection proxy provides the stored data to the client terminal thus avoiding a surge in processing resources at the gateway due to the necessary downloads.

Claims

1. A method for an improved communication in an electronic trading environment, comprising:

receiving initial download data at a connection proxy, wherein the initial download data enables a client terminal to connect to an electronic exchange through an intermediary device, wherein the client terminal communicates with the electronic exchange using a communication session established for the client terminal at the intermediary device;

detecting that a network communication link between the client terminal and the intermediary device has been terminated;

providing, by the connection proxy, a signal to the intermediary device to maintain the communication session at the intermediary device for a predetermined period of time;

providing, by the connection proxy, the initial download data to the client terminal if the network communication link between the client terminal and the intermediary device is restored during the predetermined period of time; and

terminating the signal being provided by the connection proxy if the network communication link between the client terminal and the intermediary device is not restored during the predetermined period of time.

2. The method of claim 1, wherein the initial download data comprises initialization data.

3. The method of claim 1, wherein the initial download data comprises subscription data.

4. The method of claim 1, wherein the initial download data comprises data related to at least one tradable object being traded at the electronic exchange.

5. The method of claim 1, further comprising:

updating the initial download data at the connection proxy during a trading day.

6. The method of claim 1, further comprising:

receiving trade order data at the connection proxy during the predetermined period of time; and

sending the trade order data from the connection proxy to the client terminal upon detecting that the network communication link between the client terminal and the intermediary device is restored during the predetermined period of time.

7. The method of claim 6, wherein the trade order data comprises fill order data.

8. The method of claim 6, wherein the trade order data comprises order confirmation data.

9. The method of claim 1, further comprising:

storing the initial download data at the connection proxy.

10. The method of claim 1, further comprising:

receiving market data related to a tradable object at the connection proxy during the predetermined period of time; and

providing the market data related to the tradable object to the client terminal upon detecting that the network communication link between the client terminal and the intermediary device is restored during the predetermined period of time.

11. The method of claim 10, wherein the tradable object was subscribed to by the client terminal prior to detecting that the network communication link has been terminated.

12. The method of claim 1, where providing, by the connection proxy, a signal to the intermediary device comprises:

generating a heartbeat message at the connection proxy on behalf of the client terminal; and

providing the heartbeat message from the connection proxy to the intermediary device at predefined time intervals during the predefined period of time.

13. The method of claim 12, further comprising providing a signal, by the connection proxy, to terminate the communication session at the intermediary device.

14. The method of claim 1, wherein the connection proxy is located at the intermediary device.

15. The method of claim 1, wherein the connection proxy is in communication with the intermediary device.

16. The method of claim 1, further comprising:

detecting that the network communication link has been restored during the predetermined period of time.

17. The method of claim 1, further comprising:

detecting that the network communication link has not been restored during the predetermined period of time.

18. The method of claim 1, wherein the intermediary device comprises a gateway.

19. A computer readable medium having stored therein instructions executable by a processor, wherein the instructions are executable to:

receive initial download data at a connection proxy, wherein the initial download data enables a client terminal to connect to an electronic exchange through an intermediary device, wherein the client terminal communicates with the electronic exchange using a communication session established for the client terminal at the intermediary device;

detect that a network communication link between the client terminal and the intermediary device has been terminated;

provide, by the connection proxy, a signal to the intermediary device to maintain the communication session at the intermediary device for a predetermined period of time;

provide, by the connection proxy, the initial download data to the client terminal if the network communication link between the client terminal and the intermediary device is restored during the predetermined period of time; and

terminate the signal being provided by the connection proxy if the network communication link between the client terminal and the intermediary device is not restored during the predetermined period of time.
