Abstract

A method for capturing data packets sent on a network for evaluating response time performance, the network including a financial institution and a partner bank. The method includes associating a captured data packet sent to the partner bank with a captured data packet received from the partner bank, by comparing at least one coded field of a data portion of the captured data packet sent to the partner bank with at least one coded field of a captured data portion of the data packet received from the partner bank. The method also includes measuring a response time of the associated data packet received from the partner bank, relative to a transmission time of the captured data packet sent to the partner bank. The method further includes transmitting an alert message upon determining that the response time is not within an adjustable predetermined threshold, wherein the alert message includes data from a data portion of the associated data packets.

Claims

1. A non-transitory computer-readable medium having stored thereon a plurality of instructions, in response to execution by a computer-based system for capturing data packets on a network for evaluating response time performance, performs operations comprising:

capturing, by the computer-based system, a first data packet, the first data packet including an authorization request for a transaction;

capturing, by the computer-based system, a second data packet;

determining, by the computer-based system, that a response time of the second data packet relative to a transmission time of the first data packet has exceeded a predetermined threshold; and

transmitting, by the computer-based system, an alert message in response to the determination that the response time of the second data packet relative to the transmission time of the first data packet has exceeded the predetermined threshold.

2. The computer-readable medium according to claim 1, wherein the alert message includes data from a data portion of the first and second packets, the data including at least one coded field, the authorization request, and the response time.

3. The computer-readable medium according to claim 1, wherein the predetermined threshold is adjustable.

4. The computer-readable medium according to claim 3, wherein the adjustable predetermined threshold is about 2 seconds.

5. The computer-readable medium according to claim 3, wherein the adjustable predetermined threshold is adjustable to millisecond intervals.

6. The computer-readable medium according to claim 1, further comprising transmitting a warning message in response to determining that no second data packet is captured having a second pattern within a predetermined time period.

7. The computer-readable medium according to claim 6, wherein the predetermined time period is 7 seconds.

8. The computer-readable medium according to claim 6, wherein the predetermined time period is adjustable to millisecond intervals.

9. The computer-readable medium according to claim 1, wherein the alert message includes at least one of a date, a time, a credit card number, a transaction amount, a reconciliation amount, a position in the data packet, a length of the field, and the response time.

10. The computer-readable medium according to claim 1, wherein the data packets are ISO 8583 messages.

11. The computer-readable medium according to claim 1, further comprising transmitting a warning message in response to determining that a match has not occurred.

12. The computer-readable medium according to claim 1, wherein a determination is automatically made on the origin of a delay based upon a transmitted coded field data within the alert message.

13. The computer-readable medium according to claim 12, wherein a penalty for the delay is validated based upon the determination of the origin of the delay.

14. The computer-readable medium according to claim 1, further comprising determining that the first data packet includes a first pattern in a coded field and determining that the second data packet includes a second pattern in the coded field that corresponds to a first pattern of the first data packet, and wherein the first packet and the second packet each contain a header portion and a data portion distinct from the header portion, and wherein the coded field and the at least one additional coded field of the first packet are contained within the data portion of the first packet, and wherein the coded field and the at least one additional coded field of the second packet are contained within the data portion of the second packet.

15. The computer-readable medium according to claim 1, wherein each additional coded field is one of a date, a time, a credit card number, a transaction amount, a reconciliation amount, a position in the data packet, and a length of the field.

16. The computer-readable medium according to claim 1, further comprising determining a match between an additional coded field of the second data packet and an additional coded field of the first packet.

17. The computer-readable medium according to claim 1, wherein the alert message includes coded field data from a portion of at least the first data packet or second data packet.

18. The computer-readable medium according to claim 1, wherein the determining that the response time of the second data packet relative to the transmission time of the first data packet has exceeded a predetermined threshold, is in response to a determination that a match has occurred between an additional coded field of the second data packet and an additional coded field of the first data packet.

19. A computer based system, comprising:

a computer network communicating with a memory;

the memory communicating with a processor for capturing data packets on a network for evaluating response time performance; and

the processor, when executing a computer program, performs operations comprising;

capturing, by the processor, a first data packet, the first data packet including an authorization request for a transaction;

capturing, by the processor, a second data packet;

determining, by the processor, that a response time of the second data packet relative to a transmission time of the first data packet has exceeded a predetermined threshold; and

transmitting, by the processor, an alert message in response to the determination that the response time of the second data packet relative to the transmission time of the first data packet has exceeded the predetermined threshold.

20. A method comprising:

capturing, by a computer-based system for capturing data packets on a network for evaluating response time performance, a first data packet, the first data packet including an authorization request for a transaction;

capturing, by the computer-based system, a second data packet;

determining, by the computer-based system, that a response time of the second data packet relative to a transmission time of the first data packet has exceeded a predetermined threshold; and

transmitting, by the computer-based system, an alert message in response to the determination that the response time of the second data packet relative to the transmission time of the first data packet has exceeded the predetermined threshold.
