Abstract

Included are methods for facilitating routing of control data associated with a communication to a plurality of recorders. One such method, among others, includes receiving control data related to a communication and routing the received control data to at least one recorder via a layer 3 protocol.

Claims

1. An Internet protocol (IP) analyzer configured to facilitate recording of at least one communication, the IP analyzer comprising:

a processor; and

a volatile and nonvolatile memory, in which the processor executes;

logic configured to receive control data related to a communication;

logic configured to select at least one recorder that is configured to receive communication data related to the communication, wherein communication data related to the communication is sent to the selected at least one recorder via a layer 2 protocol; and

logic configured to route, via a layer 3 protocol, the received control data to the selected at least one recorder.

2. The IP analyzer of claim 1, wherein the communication traverses at least one of the following:

a wide area network (WAN) and an Asynchronous Transfer Mode (ATM) network.

3. The IP analyzer of claim 1, wherein the logic configured to receive the control data is further configured to passively receive mirrored control data.

4. The IP analyzer of claim 3, further comprising logic configured to passively receive the mirrored control data from the call control engine.

5. The IP analyzer of claim 1, further comprising logic configured to send control data to all recorders communicatively coupled to the IP analyzer.

6. The IP analyzer of claim 1, further comprising logic configured to determine an address associated with the at least one recorder that is configured to receive the communication data.

7. The IP analyzer of claim 1, further comprising logic configured to send data to a load balancer via a TCP/IP connection.

8. A method for facilitating routing of control data associated with a communication to a plurality of recorders, the method comprising:

receiving control data related to a communication at an Internet Protocol (IP) analyzer, wherein the communication is configured for transmission across a Wide Area Network (WAN) via a layer 3 protocol; and

routing the received control data by the IP analyzer to at least one recorder via a layer 2 protocol.

9. The method of claim 8, wherein routing the received control data to at least one recorder includes routing the received control data to at least one load balancer, the at least one load balancer being configured to distribute received data among a plurality of recorders.

10. The method of claim 8, further comprising selecting at least one load balancer for receiving communication data related to the communication.

11. The method of claim 8, further comprising routing the received control data to all recorders that are communicatively coupled to the WAN.

12. The method of claim 8, wherein sending control data to at least one recorder includes sending control data across a TCP/IP connection.

13. The method of claim 12, wherein the received control data includes passively received mirrored data.

14. The method of claim 8, wherein the received control data is received from a call control engine.

15. A system for routing communication data to a plurality of recorders, comprising:

at least one recorder configured to receive communications data via a layer 2 protocol and interpret at least a portion of the data received via the layer 2 protocol; and

an Internet Protocol (IP) analyzer coupled to the at least one recorder, the IP analyzer configured to;

receive control data related to the communication via the layer 2 protocol;

select at least one recorder that is configured to receive communication data related to the communication; and

route control data to the selected at least one recorder via a layer 2 protocol.

16. The system of claim 15, wherein the communication traverses at least one of the following:

a wide area network (WAN) and an Asynchronous Transfer Mode (ATM) network.

17. The system of claim 15, wherein the IP analyzer is further configured to passively receive mirrored control data.

18. The system of claim 17, wherein the IP analyzer is configured to passively receive the mirrored control data from the call control engine.

19. The system of claim 15, further comprising a plurality of recorders, at least one of the plurality of recorders being configured to receive data related to the communication.

20. The system of claim 15, wherein the IP analyzer is further configured to interpret the received data and issue at least one record command to at least one recorder.
