- What Is It?
- Fovea
is a streaming video analysis tool that is designed to monitor up to
500 simultaneous video streams. The unit gives the user the flexibility to
serve a wide range of applications associated with network performance
and its ability to support video applications.
- How Does It Work?
- The
actions of each simulated set-top box are independently controlled in
each script. These actions simulate a user controlling a set-top box
with a remote. Commands include Wait, Watch and Surf.
Wait
indicates the amount of time the user performs an action or
non-action. Watch selects a particular video stream in which the
measurements will be performed. Surf commands the Fovea to surf a range
of channels so that Zap Times can be calculated. Virtual STB's operate
either synchronously or "randomly". "Random" actions may be reproduced
thus allowing a failure mode to be recreated.
- What Does It Do?
- Fovea
simulates a user watching and changing channels. While watching a
channel, quality measurements are performed to determine the user's
overall quality experience while channel surfing, Zap Time measurements
are performed to determine how quickly network elements respond to
commands.
- What Can It Test?
-
- Quality of Service Testing
- Network Testing
- Server Congestion
