Abstract

A system and method of calculating a metric for a sub-transaction that is included in a transaction on an IP network.

Claims

1. A method comprising:

accepting an indication of a transaction on an IP network, said transaction comprising a sub-transaction; and

calculating a metric of said sub-transaction.

2. The method as in claim 1, wherein said transaction comprises a transaction on a first hierarchical level, and wherein said sub-transaction comprises a sub-transaction on a second hierarchical level, and wherein said calculating comprises calculating said metric for said second hierarchical level and comparing said metric for said second hierarchical level with said metric for said transaction on said first hierarchical level.

3. The method as in claim 2, wherein sub-transaction comprises a sub-sub-transaction, and wherein said calculating comprises calculating said metric for said sub-sub-transaction.

4. The method as in claim 1, comprising presenting an indication of said sub-transaction and an indication of said metric in a hierarchical format.

5. The method as in claim 4, comprising presenting said indication in a tree format.

6. The method as in claim 4, comprising ordering said indication of a plurality of said sub-transactions by a result of said calculating of said metric.

7. The method as in claim 1, comprising:

plotting said metric for a plurality of said sub-transactions; and

displaying a graph of said plotting.

8. The method as in claim 1, wherein said metric is selected from the group consisting of:

a response time of said sub-transaction;

a network time of said sub-transaction;

a server time of said sub-transaction;

a client time of said sub-transaction;

errors in said sub-transaction;

a size in bytes of said sub-transaction;

a number of downloaded bytes in said sub-transaction;

a number of uploaded bytes in said sub-transaction;

a number of packet in flight of said sub-transaction;

an average TCP window size in said sub-transaction

a number of retransmissions of said sub-transaction; and

an average packet size in said sub-transaction.

9. The method as in claim 1, comprising:

altering a condition of said IP network from a first condition to a second condition; and

comparing said metric for said sub-transaction upon said IP network under said first condition to said metric for said sub-transaction upon said IP network under said second condition.

10. The method as in claim 1, wherein said metric is calculated for a plurality of elements of said IP network.

11. The method as in claim 1, comprising:

altering a parameter of said sub-transaction;

calculating said metric for said sub-transaction having said altered parameter; and

comparing said metric for said sub-transaction to said metric for said sub-transaction having said altered parameter.

12. A system comprising a processor, said processor to:

accept an indication of a transaction on an IP network, said transaction comprising a sub-transaction; and

calculate a metric of said sub-transaction.

13. The system as in claim 12, wherein said transaction comprises a transaction on a first hierarchical level, and wherein said sub-transaction comprises a sub-transaction on a second hierarchical level, and wherein said processor is to calculate said metric for said second hierarchical level and compare said metric for said second hierarchical level with said metric for said transaction on said first hierarchical level.

14. The system as in claim 13, wherein said sub-transaction comprises a sub-sub-transaction, and wherein said processor is to calculate said metric for said sub-sub-transaction.

15. The system as in claim 12, wherein said processor is to present an indication of said sub-transaction and an indication of said metric in a hierarchical format.

16. The system as in claim 15, wherein said processor is to present said indication in a tree format.

17. An article having stored thereon instructions that when executed by a processor result in

accepting an indication of a transaction on an IP network, said transaction comprising a sub-transaction;

and

calculating a metric of said sub-transaction.

18. The article as in claim 17, wherein said instructions further result in:

plotting said metric for a plurality of said sub-transactions; and

displaying a graph of said plotting.

19. The article as in claim 17, wherein said instructions further result in:

calculating said metric, said metric selected from the group consisting of;

a response time of said sub-transaction;

a network time of said sub-transaction;

a server time of said sub-transaction;

a client time of said sub-transaction;

errors in said sub-transaction;

a size in bytes of said sub-transaction;

a number of downloaded bytes in said sub-transaction;

a number of uploaded bytes in said sub-transaction;

a number of packet in flight of said sub-transaction;

an average TCP window size in said sub-transaction

a number of retransmissions of said sub-transaction; and

an average packet size in said sub-transaction.

20. The article as in claim 17, wherein said instructions further result in:

altering a condition of said IP network from a first condition to a second condition; and

comparing said metric for said sub-transaction upon said IP network under said first condition to said metric for said sub-transaction upon said IP network under said second condition.

21. The article as in claim 17, wherein said instructions further result in calculating said metric for a plurality of elements of said IP network.
