What Is It?
Fovea is a streaming video analysis tool that is designed to
monitor up to 500 simultaneous video streams. The unit give the
user flexibility to serve a wide range of applications
associated with network performance and its ability to support
video applications.
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.
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-actions. 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 Can It Test?
- Quality of Service Testing
- Network Testing
- Server Congestion
