Abstract

Claims (64)

1. A method for adjusting results during network analysis, comprising:

receiving network communications, wherein the network communications include packets;

processing the network communications utilizing first hardware to generate first results;

processing the network communications utilizing second hardware to generate second results;

identifying a number of packets processed by the first hardware;

identifying a number of packets dropped by the second hardware; and

adjusting at least one of the first results and the second results for conforming with the other;

wherein the adjusting is carried out based on the number of packets processed by the first hardware and the number of packets dropped by the second hardware.

2. The method as recited in claim 1 , wherein the first hardware includes network interface card (NIC) hardware.

3. The method as recited in claim 1 , wherein the second hardware includes a network analyzer processor.

4. The method as recited in claim 1 , wherein the first hardware and the second hardware are situated on separate network cards.

5. The method as recited in claim 1 , wherein the first hardware and the second hardware are situated on a single common network card.

6. The method as recited in claim 1 , wherein the results include statistics, at least in part.

7. The method as recited in claim 1 , wherein the results include statistics.

8. The method as recited in claim 1 , wherein the adjusting is conditionally carried out.

9. The method as recited i claim 8 , wherein the adjusting is conditionally carried out based on a threshold.

10. The method as recited in claim 9 , wherein the threshold is based on the number of packets dropped by the second hardware.

11. The method as recited in claim 1 , wherein the results include remote monitoring (RMON) statistics.

12. The method as recited in claim 11 , wherein the results include a RMON statistics group.

13. A method for adjusting results during network analysis, comprising:

receiving network communications;

processing the network communications utilizing first hardware to generate first results;

processing the network communications utilizing second hardware to generate second results; and

adjusting at least one of the first results and the second results for conforming with the other;

wherein the adjusting is carried out on a statistic using the formula

S′=S− (S* P dropbyhw2 /P prxbyhw1 ),

where S′ is an adjusted statistic, S is an original statistic, P dropbyhw2 is a number of packets dropped by the second hardware, and P prxbyhw1 is a number of packets processed by the first hardware.

14. A computer readable medium having stored thereon a computer program product encoded with instructions being executed by a computer for adjusting results during network analysis, comprising:

computer code for receiving network communications, wherein the network communications include packets;

computer code for processing the network communications utilizing first hardware to generate first results;

computer code for processing the network communications utilizing second hardware to generate second results;

computer code for identifying a number of packets processed by the first hardware;

computer code for identifying a number of packets dropped by the second hardware; and

computer code for adjusting at least one of the first results and the second results for conforming with the other,

wherein the adjusting is carried out based on the number of packets processed by the first hardware and the number of packets dropped by the second hardware.

15. A system for adjusting results during network analysis, comprising:

means for receiving network communications, wherein the network communications include packets;

means for processing the network communications utilizing first hardware to generate first results;

means for processing the network communications utilizing second hardware to generate second results;

means for identifying a number of packets processed by the first hardware;

means for identifying a number of packets dropped by the second hardware; and

means for adjusting at least one of the first results and the second results for conforming with the other,

wherein the adjusting is carried out based on the number of packets processed by the first hardware and the number of packets dropped by the second hardware.

16. A system for adjusting results during network analysis, comprising:

first hardware for receiving network communications and processing the network communications to generate first results; and

second hardware for processing the network communications to generate second results;

wherein at least one of the first results and the second results is adjusted for conforming with the other,

wherein the adjusting is carried out based on a number of packets processed by the first hardware and a number of packets dropped by the second hardware.

17. A method for adjusting results during network analysis, comprising:

receiving network communications;

processing the network communications utilizing first hardware including network interface card (NIC) hardware to generate first results;

identifying a number of packets processed by the first hardware;

processing the network communications utilizing second hardware including a network analyzer processor to generate second results;

identifying a number of packets dropped by the second hardware;

determining whether the number of packets dropped by the second hardware exceeds a predetermined threshold; and

adjusting at least one of the first results and the second results based on the number of packets processed by the first hardware and the number of packets dropped by the second hardware, if it is determined that the number of packets dropped by the second hardware exceeds a predetermined threshold.

18. A method for adjusting results during network analysis, comprising:

receiving network communications, wherein the network communications include packets;

processing the network communications to generate first results;

processing the network communications to generate second results;

identifying a number of packets processed by a first hardware;

identifying a number of packets dropped by a second hardware; and

adjusting at least one of the first results and the second results for conforming with the other;

wherein the adjusting is carried out based on the number of packets processed and the number of packets dropped.
