In-line FIX packet translator
Certain embodiments provide systems and methods to perform in-line translation of message content according to FIX protocol variants in a trading system. An example method includes receiving, at a computing device, a message formatted according to a FIX protocol, the message including message content and a message wrapper, the message wrapper providing session and delivery information for the message to a target. The example method includes performing in-line translation of the message content of the received message to adjust the message content according to a predefined set of rules without affecting the message wrapper (with the possible exception of the message size) and message routing session. The example method includes facilitating routing of the message to the target based on the message wrapper.
1. A system including:
a computing device,
wherein the computing device is configured to receive a message from a sender device to be sent to a target device, wherein the sender device and the target device communicate using a communication session established directly between the sender device and the target device, wherein the message is formatted according to a first FIX protocol and includes application level trade order related data in a message body and session level data in a message wrapper;
wherein the computing device is configured to perform in-line translation of the application level trade order related data formatted according to the first FIX protocol in the received message to generate application level trade order data formatted according to a second FIX protocol being used at the target device, wherein the in-line translation does not modify content of the session level data in the message wrapper; and
wherein the computing device is configured to route the message including the message body including the application level trade order related data formatted according to the second FIX protocol and the message wrapper including the session level data to the target device.
2. The system of claim 1 , wherein the session level data comprises a sequence number of a packet, wherein the sequence number remains unchanged after the in-line translation is performed.
3. The system of claim 1 , wherein the session level data comprises a packet identifier, wherein the packet identifier remains unchanged after the in-line translation is performed.
4. The system of claim 1 , wherein the first FIX protocol is associated with the sender device comprising a client device, and wherein the second FIX protocol is associated with the target device comprising an electronic exchange.
5. The system of claim 1 , wherein the computing device is implemented as an integrated circuit.
6. The system of claim 5 , wherein the integrated circuit comprises a field programmable gate array.
7. The system of claim 1 , wherein the computing device is at a gateway.
8. The system of claim 1 , wherein the computing device is at a network transmission switch associated with a gateway.
9. The system of claim 1 , wherein the computing device comprises a predefined set of rules to map data from the first FIX protocol to the second FIX protocol.
10. The system of claim 9 , wherein the predefined set of rules comprises mapping of terms between the first FIX protocol to the second FIX protocol.
11. The system of claim 1 , wherein the computing device is at an electronic exchange.
12. The system of claim 1 , wherein the session level data comprises routing data.
13. The system of claim 1 , wherein the session level data comprises message identification data.
14. The system of claim 1 , wherein the message wrapper is a FIX message envelope.
15. The system of claim 1 , wherein the sender device is a client device.
