Abstract

Claims (30)

1. A system for processing a plurality of data packets from a plurality of financial market data feeds, wherein each of a plurality of the data packets comprises (1) a destination address that identifies a destination for the data packet, (2) a source address that identifies a source for the data packet, (3) a protocol identifier that identifies a protocol for the data packet, and (4) a packet payload, the packet payload comprising plurality of financial market data messages, the financial market data messages comprising a plurality of fields of financial market data pertaining to a plurality of financial instruments, the system comprising:

a network element of a data distribution network through which data packets are communicated to an electronic trading platform, wherein the network element comprises a packet switch, a repeater, a router, or a firewall, the network element comprising a processor, the processor configured to:

receive the data packets; and

for each of a plurality of the received data packets, (1) map the received data packet to parsing metadata applicable to the received data packet based on the received data packet's destination address, source address, and protocol identifier and (2) append a field to the received data packet, wherein the appended field comprises the parsing metadata; and

wherein the network element is configured to communicate the data packets to the destinations corresponding to the destination addresses of the data packets, wherein the communicated data packets include the appended fields, the network element thereby being configured to offload tasks for mapping parsing metadata to data packets from the electronic trading platform.

2. The system of claim 1 wherein the parsing metadata includes an identifier for the financial market data feed for the data packet to which the parsing metadata is applicable.

3. The system of claim 2 wherein the parsing metadata further includes an identifier for a line within the financial market data feed for the data packet to which the parsing metadata is applicable.

4. The system of claim 1 wherein the parsing metadata includes an identifier for an exchange that pertains to the data packet to which the parsing metadata is applicable.

5. The system of claim 1 wherein the parsing metadata includes a packet parsing template that identifies how the data packet is to be parsed.

6. The system of claim 1 wherein the parsing metadata includes a message parsing template that identifies how the financial market data messages of the data packet are to be parsed into their constituent fields of financial market data.

7. The system of claim 1 wherein the processor is further configured to, for each of a plurality of the received data packets, map the received data packet to its corresponding parsing template using a hash key and a hash table, wherein the hash key is based on the destination address, the source address, and the protocol identifier of the received data packet.

8. The system of claim 1 wherein the processor comprises a field programmable gate array (FPGA).

9. The system of claim 1 wherein the processor comprises an application-specific integrated circuit (ASIC).

10. The system of claim 1 wherein the processor comprises a graphics processing unit (GPU).

11. The system of claim 1 wherein the processor comprises a chip multi-processor (CMP).

12. The system of claim 1 wherein the network element comprises the packet switch, wherein the packet switch comprises (1) a plurality of ports for receiving and communicating the data packets, (2) a switching fabric, and (3) the processor.

13. The system of claim 12 wherein the packet switch provides 10 Gigabit Ethernet connectivity for receiving and communicating the data packets via a plurality of the ports.

14. The system of claim 1 further comprising:

a ticker plant configured to receive the communicated data packets and parse the received communicated data packets into a plurality of parsed fields based on the parsing metadata included in the appended fields, wherein the ticker plant comprises a field programmable gate array (FPGA), the FPGA configured to generate composite views of a plurality of financial instruments based on a plurality of the parsed fields.

15. The system of claim 1 further comprising:

a ticker plant configured to receive the communicated data packets and parse the received communicated data packets into a plurality of parsed fields based on the parsing metadata included in the appended fields, wherein the ticker plant comprises a field programmable gate array (FPGA), the FPGA configured to perform last value cache (LVC) updates for a plurality of financial instruments based on a plurality of the parsed fields.

16. A method for processing a plurality of data packets from a plurality of financial market data feeds, the method comprising:

receiving a data packet by a processor within a network element of a data distribution network through which data packets are communicated to an electronic trading platform, wherein the network element comprises a packet switch, a repeater, a router, or a firewall, wherein the received data packet comprises (1) a destination address that identifies a destination for the data packet, (2) a source address that identifies a source for the data packet, (3) a protocol identifier that identifies a protocol for the data packet, and (4) a packet payload, the packet payload comprising plurality of financial market data messages, the financial market data messages comprising a plurality of fields of financial market data pertaining to a plurality of financial instruments;

the processor mapping the data packet to parsing metadata applicable to the data packet based on the data packet's destination address, source address, and protocol identifier;

the processor appending a field to the data packet, wherein the appended field comprises the parsing metadata; and

the network element communicating the data packet to the destination corresponding to the destination address of the data packet, wherein the communicated data packet includes the appended field, the network element thereby offloading tasks for mapping parsing metadata to data packets from the electronic trading platform; and

performing the (1) receiving step, (2) the mapping step, (3) the appending step, and (4) and communicating step for a plurality of data packets from a plurality of financial market data feeds.

17. The system of claim 1 wherein the network element comprises the repeater.

18. The system of claim 1 wherein the network element comprises the router.

19. The system of claim 1 wherein the network element comprises the firewall.
