Measuring IPTV/MSTV QoE in Conjunction with IGMPoPPP and IGMPoDHCP
Key Features
- Highly scalable per-subscriber video quality metrics
- IGMPoPPP/DHCP support
- Microsoft TV support
(MDI and protocol decodes)
- 10 GbE video subscriber/server support
Test Objective
This application note shows how to use N2X without
the IPTV QoE Productivity Application (PA) to
make MDI quality of experience measurements on
simulated subscribers. This approach is suitable
when dynamic subscriber behavior (e.g., channel
changing) and channel zapping measurements
are not required. This approach scales to higher
levels and does not require the PA license. It is also
somewhat simpler in that it only involves a single
software product: the main N2X application.
The purpose of this test is to assess Quality of
Experience for video subscribers connecting to the
network using PPPoE or DHCP. The performance of
these access protocols is not the focus of the test.
MDI measurements are used to determine whether
video Quality of Experience is adequate when
the traffi c is delivered over PPP or when DHCPassigned
addresses are used. This Application Note
also shows how N2X can be used to make MDI
measurements on traffi c delivered from a thirdparty
source, which could be a video server or a
real Microsoft TV system.
