Abstract

A system and method for diagnosing a problem on a packet network. Network performance information associated with data packet communications over a packet network may be collected. A network performance information parameter may be monitored and a determination that the network performance information parameter crosses a threshold value may be made. In response to determining that the network performance information parameter crossed the threshold value, diagnostics may be initiated to determine a cause of the network performance information parameter crossing the threshold value.

First claim

We claim:

1. A method for diagnosing a problem on a packet network of a first communications carrier, the method comprising:
collecting network performance information at a network device, the network performance information being associated with data packet communications over the packet network and a second packet network of a second communications carrier;
monitoring a network performance information parameter within the network performance information using the network device;
avoiding sharing of confidential information by limiting result information returned by monitoring the second packet network;
determining whether the network performance information parameter crosses a threshold value;
in response to determining that the network performance information parameter crossed the threshold value, the network device initiating near-real-time diagnostics for implementation by one or more network nodes to determine a cause of the network performance information parameter crossing the threshold value;
determining a route for a voice over Internet Protocol (VoIP) call between at least two parties, based on the near-real-time diagnostics, which continues to be performed during the VoIP call; and
re-routing the VoIP call between the at least two parties, based on the near-real-time diagnostics that is performed during the VoIP call.

2. The method according to claim 1 , wherein initiating includes communicating a command to a network node to cause the network node to execute a diagnostics routine and report results thereof.

3. The method according to claim 1 , wherein initiating includes initiating a loop-back test.

4. The method according to claim 1 , wherein initiating includes initiating a trace route.

5. The method according to claim 1 , wherein monitoring the network performance information parameter includes monitoring a transmission quality parameter, wherein the second packet network in communication with the packet network initiates the collecting, monitoring, determining, and initiating for the packet network.

6. The method according to claim 5 , wherein monitoring the transmission quality parameter includes monitoring a transmission quality parameter associated with communications of data packets including real-time content.

7. The method according to claim 5 , wherein monitoring the transmission quality parameter includes monitoring a transmission quality parameter associated with communications of data packets including non-real-time content, and wherein diagnostics for real-time packet communications and non-real-time packet communications are enabled to be performed independently or jointly.

8. The method according to claim 1 , wherein monitoring the network performance information parameter includes monitoring transmission bandwidth.

9. The method according to claim 8 , wherein monitoring transmission bandwidth includes monitoring transmission bandwidth of data packets including real-time content and non-real time content.

10. The method according to claim 1 , wherein collecting the network performance information includes collecting the network performance information at a central location.

11. The method according to claim 1 , wherein the threshold value includes an upper threshold and a lower threshold.

12. The method according to claim 1 , further comprising generating a message to notify an operator of the network performance information parameter crossing the threshold and results of the diagnostics.

13. A system for diagnosing a problem on a packet network, said system comprising:
memory configured to store a database containing network performance information, the network performance information being associated with data packet communications over the packet network and a second packet network of a second communications carrier; and
a processing unit in communication with said memory, said processing unit includes at least one processor that executes instructions to:
monitor a network performance information parameter for one or more network segments between network nodes;
avoid sharing of confidential information by limiting result information returned by monitoring the second packet network;
determine whether the network performance information parameter crosses a threshold value;
in response to determining that the network performance information parameter crossed the threshold value, initiate near-real-time diagnostics to determine a cause of the network performance information parameter crossing the threshold value;
determine a route for a voice over Internet Protocol (VoIP) call between at least two parties, based on the near-real-time diagnostics, which continues to be performed during the VoIP call; and
re-routing the VoIP call between the at least two parties, based on the near-real-time diagnostics that is performed during the VoIP call.

14. The system according to claim 13 , wherein the diagnostics include communication of a command to a network node to cause the network node to execute a diagnostics routine and report results thereof.

15. The system according to claim 13 , wherein the diagnostics include a loop-back test.

16. The system according to claim 15 , wherein the diagnostics include a trace route.

17. The system according to claim 13 , wherein said at least one processor is further configured to execute instructions to monitor a transmission quality parameter, wherein the second packet network in communication with the packet network initiates the collecting, monitoring, determining, and initiating.

18. The system according to claim 17 , wherein said at least one processor is further configured to execute instructions to monitor a transmission quality parameter associated with communications of data packets including real-time content.

19. The system according to claim 17 , wherein said at least one processor is further configured to execute instructions to monitor a transmission quality parameter associated with communications of data packets including non-real-time content.

20. The system according to claim 13 , wherein said at least one processor is further configured to execute instructions to monitor the network performance information parameter by monitoring transmission bandwidth.

21. The system according to claim 20 , wherein said at least one processor is further configured to execute instructions to monitor transmission bandwidth by monitoring transmission bandwidth of data packets including real-time content and non-real time content.

22. The system according to claim 13 , wherein said at least one processor is further configured to execute instructions to collect the network performance information at a central location.

23. The system according to claim 13 , wherein said at least one processor is further configured to execute instructions to collect the network performance information at a network node, wherein the threshold value includes an upper threshold and a lower threshold, and wherein the diagnostics for the real-time and non-real-time packet communications are enabled to be performed independently or jointly.

24. The system according to claim 13 , wherein said at least one processor is further configured to execute instructions to generate a message to notify an operator of the network performance information parameter crossing the threshold and results of the diagnostics.
