Abstract

A network diagnostic system may include a statistics module. The statistics module may include a plurality of stages and may include stage-transition code. The stage-transition code may be used to help maintain one or more network diagnostic statistics. The statistics module may be implemented using a network processor unit, and the network processor unit may include a plurality of stages and may include stage-transition code. To help maintain one or more network diagnostic statistics, the statistics module may add and remove entries to a data structure.

Claims

1. A network diagnostic system comprising:

a network processor unit including;

a first stage;

a second stage; and

stage transition code configured to update at least one network diagnostic statistic associated with a network message received from the first stage.

2. The network diagnostic system as in claim 1, wherein the at least one network diagnostic statistic comprises a count.

3. The network diagnostic system as in claim 2, wherein the count indicates a number of open transactions.

4. The network diagnostic system as in claim 2, wherein the count indicates the highest number of transactions open during a time period.

5. The network diagnostic system as in claim 2, wherein the count indicates the lowest number of transactions open during a time period.

6. The network diagnostic system as in claim 1, wherein the network processor unit further includes a queue via which the stage transition code receives network messages from the first stage.

7. The network diagnostic system as in claim 1, wherein the network message is a packet.

8. A network diagnostic system comprising:

a statistics module for maintaining a set of one or more network diagnostic statistics including a first network diagnostic statistic, the statistics module including a data structure;

the statistics module configured to receive a network message associated with the first network diagnostic statistic;

to, when the received network message is a first type of network message, add an entry associated with the first network diagnostic statistic to the data structure;

to, when the received network message is a second type of network message and the data structure includes one or more entries associated with the first network diagnostic statistic, remove at least one of the entries; and

to, when the received network message is a second type of network message and the data structure does not include any entries associated with the first network diagnostic statistic, alter the first network diagnostic statistic.

9. The network diagnostic system as in claim 8, wherein the first type of network message is a close-transaction network message;

and wherein the second type of network message is an open-transaction network message.

10. The network diagnostic system as in claim 8, wherein the first network diagnostic statistic is a count indicating a number of open transactions.

11. The network diagnostic system as in claim 10, wherein the statistics module is configured to alter the first network diagnostic statistic by incrementing the count.

12. The network diagnostic system as in claim 8, wherein the first network diagnostic statistic is a count indicating the highest number of transactions open during a time period.

13. The network diagnostic system as in claim 12, wherein the statistics module is configured to alter the first network diagnostic statistic by incrementing the count.

14. The network diagnostic system as in claim 8, wherein the network message is a packet.

15. A method for using stage transition code of a network processor unit, the network processor unit including a plurality of stages, the method comprising:

using the stage transition code of the network processor to update at least one network diagnostic statistic associated with a network message received from one of the plurality of stages.

16. The method as in claim 15, wherein the at least one network diagnostic statistic comprises a count.

17. The method as in claim 16, wherein the count indicates a number of open transactions.

18. The method as in claim 16, wherein the count indicates the highest number of transactions open during a time period.

19. The method as in claim 16, wherein the count indicates the lowest number of transactions open during a time period.

20. The method as in claim 15, wherein the network processor unit further includes a queue via which the stage transition code receives network messages from the first stage.

21. The method as in claim 15, wherein the network message is a packet.
