Abstract

A method of monitoring quality of a telephone call transmitted over a network includes obtaining a metric associated with the telephone call, where the metric is based on data packets that are transmitted during the telephone call, and determining whether the metric exceeds a threshold. Plural metrics may be obtained and the method may determine whether the plural metrics exceed corresponding thresholds.

Claims (31)

1. A method of monitoring quality of a telephone call transmitted over a network, the method comprising:

performing a traceroute through the network;

obtaining a plurality of metrics associated with the telephone call, the plurality of metrics being obtained via the traceroute, and the plurality of metrics being based on data packets that are transmitted during the telephone call;

determining whether the plurality of metrics exceeds a corresponding plurality of thresholds;

increasing a frequency of the traceroute when at least one of the plurality of metrics exceeds its corresponding threshold;

after increasing the frequency of the traceroute, re-obtaining the plurality of metrics;

determining whether the re-obtained plurality of metrics exceeds the corresponding plurality of thresholds;

decreasing the frequency of the traceroute when the re-obtained plurality of metrics is determined to be below the corresponding plurality of thresholds;

receiving information from nodes of the network using the trace route, the information based on the metric exceeding the threshold;

using the information and other information relating to routing of other telephone calls through the network to locate a problem on the network, the problem comprising at least one of a bottleneck, a failed node, or a node not functioning properly; and

routing subsequent telephone calls based on the information to avoid the problem.

2. The method of claim 1 , wherein the metric comprises at least one of data packet loss and jitter of the data packets.

3. The method of claim 1 , wherein the information comprises records associated with telephone calls routed through different paths of the network.

4. The method 1 , wherein the metric relates to a degradation in call quality, the degradation represented by the metric not being detectable by a human ear.

5. The method of claim 1 , wherein the metric is weighted, the weight corresponding to a system that initiates the telephone call.

6. One or more non-transitory machine-readable media for storing instructions that are executable to monitor quality of a telephone call transmitted over a network, the instructions for causing one of more processing devices to:

perform a traceroute through the network;

obtain a plurality of metrics associated with the telephone call, the plurality of metrics being obtained via the traceroute, and the plurality of metrics being based on data packets that are transmitted during the telephone call;

determine whether the plurality of metrics exceeds a corresponding plurality of thresholds;

increase a frequency of the traceroute when at least one of the plurality of metrics exceeds its corresponding threshold;

after increasing the frequency of the traceroute, re-obtaining the plurality of metrics;

determining whether the re-obtained plurality of metrics exceeds the corresponding plurality of thresholds;

decrease the frequency of the traceroute when the re-obtained plurality of metrics is determined to be below the corresponding plurality of thresholds;

receive information from nodes of the network using the trace route, the information based on the metric exceeding the threshold;

use the information and other information relating to routing of other telephone calls through the network to locate a problem on the network, the problem comprising at least one of a bottleneck, a failed node, or a node not functioning properly; and

route subsequent telephone calls based on the information to avoid the problem.

7. The one or more non-transitory machine-readable media of claim 6 , wherein the metric comprises at least one of data packet loss and jitter of the data packets.

8. The one or more non-transitory machine-readable media of claim 6 , wherein the information comprises records associated with telephone calls routed through different paths of the network.

9. The one or more non-transitory machine-readable media of claim 6 , wherein the information is limited to records associated with telephone calls routed through different paths of the network.

10. The one or more machine-readable media 6 , wherein the metric relates to a degradation in call quality, the degradation represented by the metric not being detectable by a human ear.

11. The one or more machine-readable media of claim 6 , wherein the metric is weighted, the weight corresponding to a system that initiates the telephone call.
