Admission Control
Media Flow Controllers are designed to track the interface stats (RX bytes and TX bytes) on
every network interface.
In a typical setup, the TX bytes would be the content delivered by the Media Flow Controller
while the RX bytes would the data fetched from the origin server. The Media Flow Manager
Central Management Console (CMC) feature fetches the interface stats from the Media Flow
Controllers at regular intervals (20 seconds).
These RX and TX stats from the various Media Flow Controllers are then collated to calculate
the delivered bandwidth and the received bandwidth.
Admission Control leverages the interface statistics from the Media Flow Controllers and
controls the outgoing bandwidth for the content served by the Media Flow Controllers using
the Service Director.
Media Flow Controller(s) Transmit Bandwidth
This graph show the historical transmit bandwidth of each Media Flow Controller managed by
this CMC. Includes Pause and Resume buttons to stop/start graph charting.
Current Status—Includes the Last Measured Bandwidth and Admission Control status.
Current Configuration—Shows the current High Bandwidth Watermark, Low Bandwidth
Watermark, and Sampling Frequency settings.
Media Flow Controller Interfaces Monitored—Shows which interface monitoring is taking
place on for each managed Media Flow Controller. Monitoring should happen on the interface
that receives and delivers traffic.
