Abstract
An alarm generation tool that operates within a Voice over IP (VoIP) network environment to generate alarms based on ISDN disconnect cause codes. The tool examines call-specific usage records associated with VoIP traffic to detect ISDN disconnect cause codes and determines failure rate information from failure-type disconnect cause codes among the ISDN disconnect cause codes on a per-gateway basis. The tool generates alarms when the failure rate information, such as failure rates and/or counts, exceeds defined thresholds.
Claims20
A method of detecting network failures in a packet-based voice network, the method comprising:
- evaluating call usage records associated with traffic on the packet-based voice network to identify failure rate information from the call usage records, wherein the failure rate information represents disconnect activities resulting from a malfunction associated the packet-based voice network;
- analyzing the failure rate information against a defined failure rate threshold;
- and
- generating an alarm if the failure rate information exceeds the defined failure rate threshold.
A computer readable medium having computer-executable instructions for performing a method for detecting network failures in a packet-based voice network, the method comprising:
- evaluating call usage records associated with traffic on the packet-based voice network to identify failure rate information from the call usage records, wherein the failure rate information represents disconnect activities resulting from a malfunction associated the packet-based voice network;
- analyzing the failure rate information against a defined failure rate threshold;
- and
- generating an alarm if the failure rate information exceeds the defined failure rate threshold.
A computer-implemented method of detecting network failures in a Voice over IP (VoIP) network, the method comprising:
- producing a failure rate based on disconnect cause codes of VoIP call usage records associated with VoIP call traffic handled by a particular VoIP network element for a given time interval;
- determining if the failure rate exceeds a defined threshold;
- and
- generating an alarm if it is determined that the failure rate exceeds the defined threshold.
