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.
