Witbe OTT Monitoring
Technologies for
Broadcasters
Measure and improve end-users' Quality of Experience, in a scalable, non-intrusive manner...

W

itbe's
OTT
monitoring
technologies aim to give any
broadcaster a true monitoring system
over unmanaged delivery networks.
Through the use of active and networkagnostic Witbe Robots, and the latest
Witbe Central System innovations,
Witbe provides broadcasters with
deep knowledge about the end-users'
Quality of Experience on its OTT
services.
Witbe technologies do more than
revealing the true impact of CDN
servers' issues on OTT's QoE with
Witbe Smartping. They also give a
real-time, global, and meaningful view
of OTT delivery infrastructure with
Witbe Earth. Completed by an easy-touse administration platform and plugand-play Robots (appliances or on
virtual machines), Witbe technologies
allow broadcasters to quickly scale up
their control on their video services'
quality.

Witbe Robots, as appliances or virtual
machines, can monitor OTT services at
the origin, at a CDN edges, or after any
consumer broadband line, to provide
a large ABR monitoring coverage,
including over Wi-Fi or 4G-LTE.
At the origin servers Witbe Robots
control the availability of all streams
- manifest files, encryption keys, and
chunks presence. Then, at CDN edges,
Witbe Robots check the performance
of the streams, ensuring that the
chunks can be downloaded correctly.
They proactively detect rebuffering
risks, content loop, and black and
frozen screen issues. They perform
active requests of video streams
as a real end-user would do using
any multiscreen application, giving
them the ability to support the most
popular ABR streaming formats,
including Adobe HDS, Apple HLS,
Microsoft Smooth Streaming, and
MPEG-DASH.

OTT Services: What Truly
Matters is the End-Users'
Quality of Experience
Witbe's OTT monitoring technologies
are network-agnostic - they're built
on the Witbe Robots, automated
interactive test appliances which
do not interfere with network
performance. Witbe Robots are
designed to monitor availability and
performance of adaptive bitrate
(ABR) assets in real time with active
requests, acting as real endusers would do.

Witbe Smartping: Map the
Impossible, Locate Bottlenecks
Witbe's OTT monitoring technologies
help prevent end-user complaints
through two unique algorithms: the
Witbe Smart Alerting System and the
Witbe Smartping. The Smart Alerting
System, a double-checking alerting
algorithm embedded in Witbe Robots,
proactively detects any relevant
delivery interruption at the critical
nodes. Acting alongside it, the Witbe
Smartping maps the impossible.
It locates the bottlenecks in your
delivery chain without interfering
with it, being network-agnostic and
imperceptible. These capabilities
show broadcasters the network
routes taken for their unmanaged
OTT service delivery, locating
the critical nodes in the delivery
infrastructure, and providing
them with impact analysis on
Witbe Smartping locates
the bottlenecks in your
delivery chain without
interfering with it

Witbe Earth shows the an delivery chain on one screen

the quality delivered. By pinpointing
the defective CDN servers' routes,
broadcasters can now enforce their
SLAs with third parties, without
owning the whole delivery networks.
Witbe Earth: All Your Delivery
Chain on One Screen
Continuous
CDN
servers'
performance supervision is provided
by the Witbe Portal, a web-based
dashboard. It aggregates the data
from the Robots, on a single interface,
with a unique cross-reference
data feature through intelligible
infographics (graphs, pie charts, etc.).
This feature allows broadcasters to
create real knowledge on various
levels:
infrastructure;
quality;
marketing, etc. Furthermore, any
severe situation can be quickly
detected using Witbe Earth. It
displays, on one screen, a real-time
tracking on CDN servers' performance,
availability, and workload around the
world, from a top point-of-view and
in real time. Broadcasters can now
detect service downtime instantly,

and become fully aware of their OTT
delivery chain.
