IPTV Testing with the FTB-8510B
IPTV Testing with the FTB-8510B
The FTB-8510B module provides the capability to monitor 10 (default)
streams in parallel when the SK-IPTV-MON option is enabled. The IPTV
monitoring capacity can be increased to 100 streams when the
SK-IPTV-MAXSTREAM is also enabled.
The FTB-8510B IPTV software option provides over 45 different metrics and
statistics including Media Delivery Index (MDI) and TR 101 290 metrics. The
TR 101 290 includes PCR jitter and Priority 1 metrics. In addition, other key
statistics such as IP packet metrics, stream rate, presence measurements
and bandwidth utilization are available. These are necessary to correctly
characterize an IPTV stream. MDI and TR 101 290 Priority 1 metrics are only
available for Single Program Transport Stream (SPTS) MPEG-2 TS streams.
Additionally, configurable alarm thresholds are provided on selected
metrics for customized testing applications.
Important usability features include the auto-discovery of all valid media
streams and user-definable stream labels for easy identification. The Auto–
Discovery feature will automatically scan the network test point and
display all IPTV streams carrying MPEG-2 TS traffic. Selecting which
streams to monitor is accomplished by automatically adding the streams
from the auto-discovery pool or by manually selecting them.
The Internet Group Management Protocol (IGMP) is a communication
protocol used to manage the membership of Internet Protocol multicast
groups. Depending on the location in the network and intended
measurements, the IPTV streams may not be directly available. For a
network element port, IGMP join requests must be used to access the
stream. Up to one hundred IGMP requests (join/leave) can be issued at
once.
For example when connecting on a switch port an IGMP join request may
be required to access each multicast streams. When connecting to a SPAN
or TAP port, the auto-discovery and auto-add features allow to add stream
as they are discovered.
