Tcp/Ip Network Connection Quality Testing (Tcp/Ip Ping) - Planar IT-100 Operating Manual

values, and the number of ES and SES errored seconds in the time interval at the
marker position;
5) ES/SES grid. Features the grid with vertical marks matched with the timing
diagram. In case at least one severe error (SES) is detected in the time interval, a
red mark is indicated, and if an ES error is detected, a green mark is indicated.
This grid allows determining whether errors were detected during measurement,
and how they are grouped in time. The indicator of the time passed is shown
under the grid in the form of a line.
The parameter to be viewed on the diagram can be selected using the dropdown
menu of F2 / View. To move the cursor, use the ◄ and ► keys. By pressing these keys
along with the Shift key, the cursor can be moved with a larger pitch.
To view the detailed measurement results obtained during all measurement time,
press the F4 / Total key. The table includes the following information:
1) ES total. Total number of errored seconds during all measurement time;
2) SES total. Total number of severely errored seconds during all measurement
time;
3) DF min/max. Minimum and maximum DF values during all measurement time;
4) DF avr. Average DF value during all measurement time;
5) MLT. The number of lost MPEG packets during all measurement time;
6) IAT min/max. Minimum and maximum IAT values during all measurement time;
7) IAT avr. Average IAT value during all measurement time;
8) IP bitrate. Average IP stream bitrate during all measurement time;
9) MPEG bitrate. Average MPEG stream bitrate during all measurement time.
Measurement results can be saved to a file upon completion or forced stop of
measurement by pressing the F5 / Save key. Specify the page name in the popup field
and press ENTER. In case a USB flash drive is connected to the Analyzer, the page will
be saved to it, otherwise the page will be saved to the internal drive. You can view the
measurement results saved to a file in the file manager (section 4.9), by selecting the IPTV
Statistics file type.

4.5.4. TCP/IP network connection quality testing (TCP/IP ping)

This mode displays the results of connection quality testing in TCP/IP networks. The
screen view and the data displayed are presented in fig. 4.48.
Connection quality testing in TCP/IP networks is carried out by sending an ICMP
echo request and receiving an echo response from the remote network node. Quality
evaluation is performed using the data on echo response packet integrity, as well as the
time between sending the request and receiving the response.
