Abstract

A system, method, and apparatus are directed towards managing a Voice over IP (VOIP) message over a network. A computing device may be configured to select a network connection for which to send the message to a destination based on a variety of factors. Duplicate message packets may be communicated to the destination device through multiple network connections. The multiple network connections may include a peer-to-peer network connection, a peer network connection, an ad-hoc network connection, or the like. Metrics may be collected about the multiple network connections. A determination may be made based, in part, on the metrics whether one network connection is optimal over another network connection. If so, that network connection may be selected to continue to provide the message packets, and the communication of the duplicate packets is ceased.

Claims

1. A method for use in managing a message over a network, comprising:

duplicating each packet in a plurality of packets;

sending the duplicate packets to a destination device over multiple network connections;

gathering metrics associated with each of the multiple network connections; and

if the metrics indicate one network connection within the multiple network connections is optimal, selecting the optimal network connection to send another plurality of packets, and discontinuing the sending of the duplicate packets over the multiple network connections.

2. The method of claim 1, wherein the message is a Voice over Internet Protocol (VOIP) message.

3. The method of claim 1, wherein the message is at least one of an audio message, or a video message.

4. The method of claim 1, further comprising:

if the metrics indicate an absence of one network connection as being optimal within the multiple network connections, selecting a default network connection to send the other plurality of packets, and discontinue the sending of duplicate packets over the multiple network connections.

5. The method of claim 4, wherein the multiple network connections include a peer network connection and a peer-to-peer network connection, and the default network connection is the peer-to-peer network connection.

6. The method of claim 1, further comprising:

if a network connection between the source device and its associated Internet Service Provider (ISP) or a network connection between the destination device and its respective ISP is determined to be of an insufficient bandwidth to manage duplicate packet flows, selecting a network connection from the multiple network connections based on historical metrics, and employing the selected network connection to send the plurality of packets to the destination device.

7. The method of claim 1, wherein the multiple network connections further comprise at least one of a peer network connection and a peer-to-peer network connection.

8. The method of claim 1, further comprising:

storing the metrics.

9. The method of claim 1, wherein the method is implemented within a mobile device.

10. The method of claim 1, wherein the method is implemented as computer-readable instructions within an IM client application.

11. A method for use in managing a Voice over IP (VOIP) message over a network, comprising:

sending duplicate VOIP packets to a destination device over multiple network connections for a predetermined time;

gathering metrics associated with each of the multiple network connections for the predetermined time; and

if the metrics indicate one network connection within the multiple network connections is optimal, selecting the optimal network connection to send additional VOIP packets, and discontinue sending of duplicate VOIP packets over the multiple network connections.

12. The method of claim 11, wherein the multiple network connections further comprise at least a peer network connection and a peer-to-peer network connection.

13. A client device for use in managing a Voice over IP (VOIP) message over a network, comprising:

a transceiver for receiving and sending information to another computing device;

a processor in communication with the transceiver; and

a memory in communication with the processor and for use in storing data and machine instructions that causes the processor to perform a plurality of operations, including;

duplicating each VOIP packet in a plurality of VOIP packets;

providing the duplicate VOIP packets to a destination device over multiple network connections;

gathering metrics associated with each of the multiple network connections; and

if the metrics indicate one network connection within the multiple network connections is optimal, selecting the optimal network connection to send another plurality of VOIP packets, and discontinuing the sending of duplicate VOIP packets over multiple network connections.

14. The client device of claim 13, wherein the VOIP message further comprises at least one of a Session Initiation Protocol (SIP) packet, a Real-time Transport Protocol (RTP) packet, or a Real-time Transport Control Protocol (RTCP) packet.

15. The client device of claim 13, wherein the processor performs a plurality of operations, further comprising:

if the metrics indicate an absence of one network connection as being optimal, selecting a default network connection to send the other plurality of VOIP packets, and discontinuing the sending of duplicate VOIP packets over multiple network connections.

16. The client device of claim 13, wherein the processor performs a plurality of operations, further comprising:

if a network connection between the source device and its associated Internet Service Provider (ISP) or a network connection between the destination device and its respective ISP is determined to be of an insufficient bandwidth to manage duplicate VOIP packet flows, selecting a network connection from the multiple network connections based on historical metrics, and sending the plurality of VOIP packets to the destination device over the selected network connection.

17. The client device of claim 13, wherein the multiple network connections further comprise at least one of a peer network connection, and a peer-to-peer network connection.
