Abstract

Methods and systems for coordinated monitoring of network transmission events. Predetermined information for the network transmission event is obtained at a first network location and the network transmission event predetermined information is provided to a predetermined monitoring location (or server). From the predetermined monitoring location, the predetermined information is provided to other network monitoring devices at one or more other network locations. At the one or more other network locations, the network transmission event, corresponding to the predetermined information obtained at the first location, is monitored. Network transmission event information, corresponding to the predetermined information obtained at the first location, is provided to the predetermined monitoring location from the first location and the other network locations. The monitoring of network transmission can be thereby coordinated.

Claims

1. A method for coordinated monitoring of network transmission events, the method comprising:

monitoring a network transmission event at a network location using a first network monitoring device;

detecting a predetermined condition in the network transmission event at the network location;

obtaining, at the network location, predetermined information relating to the network transmission event;

providing the predetermined information from the first network monitoring device to a predetermined monitoring location;

providing, from the predetermined monitoring location, the predetermined information to at least one second network monitoring device at an at least one other network location;

monitoring, at the at least one other network location, the network transmission event corresponding to the predetermined information; and

providing, to the predetermined monitoring location, information relating to the network transmission event, the information being obtained at the network location and the at least one other network location.

2. The method of claim 1 further comprising

determining a location and nature of a root cause of the predetermined condition.

3. The method of claim 1 wherein the network transmission comprises a network transmission utilizing an Internet Protocol.

4. The method of claim 3 wherein the network transmission event is a voice over Internet Protocol (IP) transmission.

5. The method of claim 3 where in the predetermined condition is obtained from data according to a real time protocol.

6. A system for coordinated monitoring of network transmission events, the system comprising:

a network monitoring subsystem capable of monitoring a network transmission event at a network location, said network monitoring subsystem having processing capabilities;

means for detecting a predetermined condition in the network transmission event at the network location;

means for obtaining, at the network location, predetermined information relating to the network transmission event;

a predetermined monitoring subsystem having processing capabilities;

means for providing the predetermined information from the network monitoring subsystem to said predetermined monitoring subsystem;

another network monitoring subsystem at another network location, said another network monitoring subsystem having processing capabilities;

means for providing, from said predetermined monitoring subsystem, the predetermined information to said another network monitoring subsystem at the another network location;

means for monitoring, at the another network location, the network transmission event corresponding to the predetermined information; and

means for providing from said network monitoring subsystem and said another network monitoring subsystem, to the predetermined monitoring subsystem, information related to the network transmission event.

7. The system of claim 6 wherein the network transmission comprises a network transmission utilizing an Internet Protocol.

8. The system of claim 7 wherein the network transmission event is a voice over Internet Protocol (IP) transmission.

9. The system of claim 7 wherein the predetermined condition and the information related to the network transmission event are obtained from data according to a real time protocol.

10. A computer program product comprising:

at least one non-transitory computer usable medium having computer readable code embodied therein, the computer readable code capable of causing at least one processor to;

monitor a network transmission event at a network location using a first network monitoring device;

detect a predetermined condition in the Network transmission event at the network location;

obtain, at the network location, predetermined information for the network transmission event;

provide the predetermined information from the first network monitoring device to a predetermined monitoring location;

provide, from the predetermined monitoring location, the predetermined information to at least one second network monitoring device located at an at least one other network location;

monitor, at the at least one other network location, the network transmission event corresponding to the predetermined information using the second network monitoring device; and

provide, to the predetermined monitoring location, information relating to the network transmission event, the information being obtained at the network location and the at least one other network location.

11. The computer program product of claim 10 wherein the computer readable code is also capable of causing at least one processor to:

determine a location and nature of a root cause of the predetermined condition.

12. The computer program product of claim 10 wherein the network transmission comprises a network transmission utilizing an Internet Protocol.

13. The computer program product of claim 12 wherein the network transmission event is a voice over Internet Protocol (IP) transmission.

14. The computer program product of claim 10 wherein the predetermined condition and the information relating to the network transmission event are obtained from data according to a real time protocol.
