Abstract

A network diagnostic system may include a network diagnostic module. The network diagnostic module may be configured to generate one or more network diagnostic statistics. The network diagnostic module may be configured to automatically handle multiple data transmission rates.

Claims

1. A network diagnostic system comprising:

a first tier that includes;

a network diagnostic module configured to generate one or more network diagnostic statistics;

the network diagnostic module being configured to, when connected to a first link transmitting data at a first data transmission rate, automatically apply the first data transmission rate to receive first data from the first link and generate one or more first network diagnostic statistics using at least a portion of the first data when the network diagnostic module is in sync with the first link and to generate one or more second network diagnostic statistics when the diagnostic module is not in sync with the first link;

the network diagnostic module being configured to, when disconnected from the first link and connected to a second link transmitting data at a second data transmission rate that is different from the first data transmission rate, automatically apply the second data transmission rate to receive second data from the second link and generate one or more third network diagnostic statistics using at least a portion of the second data when the network diagnostic module is in sync with the second link and to generate one or more fourth network diagnostic statistics when the diagnostic module is not in sync with the second link;

a second tier configured to collect statistics generated by the diagnostic module; and

a third tier configured to provide visualizations of the collected statistics.

2. The network diagnostic system of claim 1, further comprising a printed circuit board that includes the network diagnostic module.

3. The network diagnostic system of claim 1, further comprising a chassis computing system that includes at least one blade that includes the network diagnostic module.

4. The network diagnostic system of claim 1, further comprising an appliance that includes the network diagnostic module and a storage device.

5. The network diagnostic system of claim 1, wherein the first data transmission rate is approximately x;

wherein x=((1.0625 Gigabits/second)*a); and

wherein a is an integer greater than 0.

6. The network diagnostic system of claim 5, wherein the second data transmission rate is approximately y;

wherein y=((1.0625 Gigabits/second)*b) or ((1.25 Gigabits/second)*b) or ((1.5 Gigabits/second)*b); and

wherein b is an integer greater than 0.

7. The network diagnostic system of claim 1, wherein the first data transmission rate is approximately x;

wherein x=((1.25 Gigabits/second)*a); and

wherein a is an integer greater than 0.

8. The network diagnostic system of claim 7, wherein the second data transmission rate is approximately y;

wherein y=((1.0625 Gigabits/second)*b) or ((1.25 Gigabits/second)*b) or ((1.5 Gigabits/second)*b); and

wherein b is an integer greater than 0.

9. The network diagnostic system of claim 1, wherein the first data transmission rate is approximately x;

wherein x=((1.5 Gigabits/second)*a); and

wherein a is an integer greater than 0.

10. The network diagnostic system of claim 9, wherein the second data transmission rate is approximately y;

wherein y=((1.0625 Gigabits/second)*b) or ((1.25 Gigabits/second)*b) or ((1.5 Gigabits/second)*b); and

wherein b is an integer greater than 0.

11. A network diagnostic system comprising:

a first tier that includes;

a network diagnostic module comprising;

a message receiving module configured to, when disconnected from a first link transmitting data at a first data transmission rate and connected to a second link transmitting data at a second data transmission rate that is different from the first data transmission rate, automatically apply the second data transmission rate to receive first data from the second link; and

a statistics module configured to generate one or more first network diagnostic statistics using at least a portion of the first data from the second link when the network diagnostic module is in sync with the second link and to generate one or more second network diagnostic statistics when the diagnostic module is not in sync with the second link;

a second tier configured to collect statistics generated by the diagnostic module; and

a third tier configured to provide visualizations of the collected statistics.

12. The network diagnostic system of claim 11, wherein the first data from the second link comprises a plurality of network messages;

wherein the message receiving module is configured to process the plurality of network messages into at least one message having an alternate structure; and

wherein the statistics module configured to generate one or more network diagnostic statistics using the at least one message having an alternate structure.

13. The network diagnostic system of claim 11, further comprising a printed circuit board that includes the network diagnostic module.

14. The network diagnostic system of claim 11, further comprising a chassis computing system that includes at least one blade that includes the network diagnostic module.

15. The network diagnostic system of claim 11, further comprising an appliance that includes the network diagnostic module and a storage device.
