RTP Video Measurements

The values on the RTP Video tab.

The MN (client) side of the test is reported in the L3 Client, L4 Client, and L5-7 Client tabs and The Network (server) side is reported in the L3 Server, L4 Server and L5-7 Server tabs (measurements from the Network Host emulator used in the test). These measurements are available when Data Traffic is included in the test.

NOTES:

Data Traffic measurement are on L3, L4, and L5-7 tabs.
Network measurement on the L3 Server tab titles are preceded by "Host"
Socket measurement are on L4 Client and L4 Server tabs
Basic Data measurements are on L5-7 Client|Basic tab
Advanced Data measurements are on L5-7 Client|Advanced tab
Network Basic Data measurements are on L5-7 Server|Basic tab titles are preceded by "Host"
Network Advanced Data measurements are on L5-7 Server|Advanced tab titles are preceded by "Host"
In the IP Application Node test case, the Summary Measurements on the L3 and L4 tabs also record DHCP packets sent and received

Measurement Values

In the default view, the Reports tab displays the Summary view, which summarizes the measurements for the test session. If your test includes multiple test cases, you can view the report for a single test case by changing the report view...

Unless otherwise noted, cumulative values report the number of occurrences or rates calculated since the start of the test, and per-interval values report the number of occurrences or rates calculated during the interval. You can view either by changing the measurement values...

Elapsed Time — The first measurement on every tab. It reports the amount of time between the start of the test and the end of the report interval.
Actual Time — The actual time shown on the Client. Actual Time is determined by the TAS. If the TAS time is wrong, Actual Time is reported wrong.
RTP Packets Sent — The number of RTP packets sent.
RTP Packets Sent/Sec (P-I) — The number of RTP packets sent per second.
RTP Sent Packets Discarded — The number of RTP sent packets that were discarded.
RTP Packets Received — The number of RTP packets received.
RTP Packets Received/Sec (P-I) — The number of RTP packets received per second.
RTP Received Packets Discarded — The number of RTP received packets that were discarded.
RTP Packets Received Out of Order — The number of RTP received packets that were received out of order.
RTP Bytes Sent — The number of RTP bytes sent.
RTP Bits Sent/Sec — The number of RTP bits sent per second.

RTP Bits Received/Sec — The number of RTP bits received per second.
RTP Packets Late Arrival — The RTP packets delayed more than the time entered in Jitter Buffer Size (RTP Video) and less than the Max Network Delay (RTP Video) are considered as late arrival.
RTP Packets Lost — If a packet does not arrive before the specified delay time set on Max Network Delay (RTP Video), it's considered as lost (RTP Packets Lost). All the packets arrived after Max Network Delay are discarded. The number of packets lost.
RTP Packet Loss Time — If a packet does not arrive before the specified delay time set on Max Network Delay (RTP Video), it's considered as lost (RTP Packets Lost). All the packets arrived after Max Network Delay are discarded.
RTP Packet Loss % (P-I) — If a packet does not arrive before the specified delay time set on Max Network Delay (RTP Video), it's considered as lost (RTP Packets Lost). Percentage of lost packets. The Packet Loss Percentage is calculated by ((Packets Lost / Packets Expected) * 100). Note: For interval 2 calculation == ((Packets Lost[2] - Packets Lost[1] / Packets Expected [2] - Packets Expected [1] ) * 100).
RTP Average Jitter (P-I) — Average jitter for RTP Packets. Notes: To get better test results for Jitter measurements (Average Jitter, Minimum Jitter, Maximum Jitter), please set as follows: 1. Set default value(15s) as "Interval Period" the Report Option (if set at 5s, you cannot get best jitter results). 2. Enable “Reserve resource for POLQA/PEVQ/IVR” 3. Use the latest Ubuntu version.
