TProtocolSelect a traceroute protocol to be used to discover intermediate routers on
To Endpoint Select an endpoint to which the RTP test is to be created. If Traffic
Simulators are connected and registered with the Controller, they will
be available in the drop-down menu for use in making new RTP tests
Codec Defines the Codec of the RTP test calls. This will alter the rate and size
of packets being sent between Traffic Simulators in order to emulate
the G.711 and G.729 codecs.
Diff Serv Code Point Defines the Differentiated Services Code Point (DSCP) of the IP Packets
of RTP test calls. Routers will treat packets differently depending on the
DSCP value set in outgoing packets. By default this value is 46
(Expedited Forwarding).
Voice Payload Size Defines the Voice Payload size of the RTP packets of a test call (in
milliseconds). Must be a multiple of 10.
Number of
Simultaneous Calls
Number of equivalent VoIP calls for a selected codec in a single test.
The default value for this setting is 2. Measurements for each call can
only be taken in one direction. When two or more calls are configured,
half of them originate at the Controller and half at the test agent so
data is collected in both directions providing a more complete
assessment of the network than if a single call were run.
Test Duration Defines the duration of each RTP test call (in seconds).
Discover Path Check this button if you want the Controller to discover intermediate
routers on the path to the endpoint.
Protocol Select a traceroute protocol to be used to discover intermediate routers
on the path to the selected endpoint.
SNMP Polling Check this button if you want the Controller to collect SNMP statistics
for devices on this path.
