Multicast Stream
Port
Destination IP Port
The destination UDP port associated with packets that contain the stream under
test. The unit determines which packets should be included in the audio/video
quality measurement based on the destination IP address and destination UDP
port pair. For multicast video, if you selected a channel from the channel guide,
this field is automatically populated.
As an option, you can select All Ports Open from the drop-down list which
indicates to ignore the port and use the IP address exclusively for identifying
video stream packets. In the case of unicast streams where packets are
addressed to a network device such as an STB, it can be difficult to determine
the UDP port(s) in use. Therefore, this option allows traffic analysis based on IP
address alone. While the STB may be receiving some data that is not part of the
video stream, it is likely that most traffic will be video data that qualifies for
analysis.
NOTE: For the most accurate results with the All Ports Open option, run
the test once to discover the precise port number, then restart the test
using that specific port.
In summary:
This field indicates the logical port that the unit will monitor for video traffic, for
the specified IP address.
•The All Ports Open option is only applicable to measuring unicast streams
(for example, video-on-demand) using passive mode. The option allows the
unit to determine the destination UDP port of the packets containing the
stream under test dynamically.
Duration Duration of the test in seconds, or Continuous to run the test until manually
stopped.
Interval Interval at which to report a full set of current measurement results, applicable to
continuous tests only.
