Abstract

The disclosed embodiments include a system and method for monitoring performance of a packet network. In one embodiment, a method includes collecting network performance information from a plurality of network nodes of a packet network, the network performance information being indicative of a health of the network packet network. The method includes storing the network performance information collected from the plurality of network nodes and generating a graphical user interface including a graphical representation of the network performance information, wherein the graphical representation of a network segment is indicated as a line, and wherein a width of the line widens and narrows in accordance with an amount of traffic flow over the network segment.

Claims

1. A call control manager for monitoring performance of a packet network for carrying voice over Internet Protocol (“

VoIP”

) calls, said call control manager comprising;

memory operable to store data and executable instructions; and

a processing unit configured to execute instructions to;

determine network performance information of a packet network by monitoring performance information packets that are communicated along network paths of the packet network;

append the network performance information gathered at a network node along the network paths to data stored in the performance information packets;

store the network performance information in memory;

analyze the stored network performance information to generate historical network performance information; and

automatically alter network operation of the packet network to provide improved performance for a VoIP call, in response to current network performance information indicating that the packet network is not operating properly based on the historical network performance information; and

determine inter-network network performance information associated with the communication of data packets between the packet network and a second packet network owned by another network service provider by monitoring a second set of performance information packets communicated between the packet network and the second packet network;

wherein the performance information packets include information indicative of time sent and counter value indicative of number of data packets sent between a previous performance information packet and a current performance information packet.

2. The call control manager according to claim 1, wherein the network performance information includes determining jitter, packet loss, and delay associated with a transmission of the performance information packets.

3. The call control manager according to claim 1, wherein the call control manager automatically alters network operation by sending a performance information packet to a network node along a network path to cause the network node to alter the network operation of the network node, append additional network performance information to the performance information packet, and transmit the performance information packet to a subsequent network node along the network path.

4. The call control manager according to claim 1, wherein the call control manager automatically alters network operation by establishing a different virtual path through a network node that would otherwise not have been established for the VoIP call, and wherein the call control manager issues a command to the same node to execute one or more self-tests associated with data packet communications at the network node, results of the one or more self-tests being communicated back to the call control manager.

5. The call control manager according to claim 1, wherein the call control manager issues a command to the network node to execute one or more self-tests associated with data packet communications at the network node, results of the one or more self-tests being communicated back to the call control manager.

6. The call control manager according to claim 1, wherein the processing unit is further configured to execute instructions to provide at least a portion of the network performance information associated with the packet network to a second network service provider, the packet network operated by a different network service provider than that of the second network service provider.

7. The call control manager according to claim 1, wherein the processing unit is further configured to execute instructions to establish one or more threshold values for use in determining a performance of the packet network including establishing an upper and lower transmission rate threshold of data packets that include real-time content, and establishing a second upper and second lower transmission rate threshold of data packets that do not include real-time content.

8. The call control manager according to claim 1, wherein the inter-network network performance information is limited to a subset of the network performance information.

9. A method for monitoring performance of a packet network for carrying voice over Internet Protocol (“

VoIP”

) calls, said method comprising;

determining, by a call control manager, network performance information of a packet network by monitoring performance information packets that are communicated along network paths of the packet network;

appending, by the call control manager, the network performance information gathered at a network node along the network paths to data stored in the performance information packets;

storing, by the call control manager, the network performance information in memory;

analyzing, by the call control manager, the stored network performance information to generate historical network performance information;

automatically altering network operation of the packet network to provide improved performance for a VoIP call, in response to current network performance information indicating that the packet network is not operating properly based on the historical network performance information; and

determining inter-network network performance information associated with the communication of data packets between the packet network and a second packet network owned by another network service provider;

wherein the performance information packets include information indicative of time sent and counter value indicative of number of data packets sent between a previous performance information packet and a current performance information packet.

10. The method according to claim 9, wherein the network performance information includes determining jitter, packet loss, and delay associated with a transmission of the performance information packets.

11. The method according to claim 9, wherein automatically altering network operation is performed by a network node along a network path, the network node receiving the performance information packet, altering the network operation of the network node, appending additional network performance information to the performance information packet, and transmitting the performance information packet to a subsequent network node along the network path.

12. The method according to claim 9, wherein automatically altering network operation comprises establishing a different virtual path through a network node than would otherwise not have been established, and wherein the call control manager issues a command to the same node to execute one or more self-tests associated with data packet communications at the network node, results of the one or more self-tests being communicated back to the call control manager.

13. The method according to claim 9, further comprising issuing a command to the network node to execute one or more self-tests associated with data packet communications at the network node, results of the one or more self-tests being communicated back to the call control manager.

14. The method according to claim 9, wherein at least a portion of the network performance information associated with the packet network is provided to a second network service provider, the packet network operated by a first network service provider.

15. The method according to claim 9, further comprising establishing one or more threshold values for use in determining a performance of the packet network including establishing an upper and lower transmission rate threshold of data packets that include real-time content, and establishing a second upper and second lower transmission rate threshold of data packets that do not include real-time content.

16. The method according to claim 9, wherein the inter-network network performance information is limited to a subset of the network performance information.
