Traffic-Shaping Adaptation Percentage - HPE FlexNetwork HSR6800 series Command Reference Manual

For interface congestion-based adaptation, the router reduces the transmission rates of all
FRTS-enabled PVCs associated with the FR class when the number of packets in the output queue
reaches the threshold. When the number of packets drops below the threshold, the router increases
the transmission rates of those PVCs.
Examples
# Enable FRTS adaptation to adjust the traffic rate in response to BECNs.

number: Specifies the rate adjustment percentage, in the range of 1 to 30.
Usage guidelines
When rate adjustment is triggered, the router reduces or increases the traffic rate by the set
percentage of the current rate. The adjusted rate must be between the CIR and the CIR ALLOW. For
example, the current rate is 3000 bps, the rate adjustment percentage is 20%, and the CIR is 2500
bps. The rate is reduced to 2400 bps (3000 – 3000 x 20%). Because the adjusted rate cannot be
lower than the CIR, the adjusted rate should be 2500 bps.
Examples
# Set the rate adjustment percentage to 20%.
