Preparing to Run the Demo

Quality of Service

The application can set threshold values to monitor the quality of service during calls. A fault occurs when the result of a measurement of a QoS parameter crossed a predefined threshold. A success occurs when the result of a measurement of a QoS parameter did not cross a predefined threshold. The QoS parameters are measured during time intervals, starting when a call is established. The following parameters are supported:

MediaAlarmLostPackets – monitors the number of lost IP packets during a call

MediaAlarmJitter – monitors the jitter (as defined in RFC 1889) during IP transmission

QoS Attributes

The threshold for each QoS parameter is measured with the following six attributes:

Threshold – defines when a QoS parameter is in a fault condition. A fault occurs when the result of a measurement of a QoS parameter crossed the Threshold value.

DebounceOn – the time during which faults are measured (in msec., must be multiple of Interval)

DebounceOff – the time during which successes are measured (in msec., must be multiple of Interval)

Interval – the amount of time between two QoS parameter measurements (in multiples of 100 msec)

Percent_Fail – used to detect failure condition, together with DebounceOn (expressed as a percentage of failures)

Percent_Success – used to detect failure recovery, together with DebounceOff (expressed as a percentage of successes)

The default values are as follows:
