Congestion Avoidance Enabled Enable or disable congestion avoidance.

HP Velocity Congestion Avoidance automatically

adjusts HP Velocity protection to accommodate

detected bandwidth constraints. When Congestion

Avoidance is active and bandwidth constraints are

detected, the bandwidth and default TLR settings

described in this table are overridden to ensure the

best network performance possible.

Bandwidth Control Dynamic Set the protection mode that HP Velocity is able to

use when encoding HP Velocity-protected flows:

• Dynamic: Use this mode in environments where

bandwidth is not constrained. It maximizes

performance while minimizing the required

bandwidth.

• Low: Use this mode in extremely bandwidth-

constrained environments to cap the estimated

HP Velocity protection overhead at or below 27%.

• Medium: Use this mode in moderately bandwidth-

constrained environments to cap the estimated

HP Velocity protection overhead at or below 40%.

• High: Use this mode to maximize performance in

environments where bandwidth is not constrained

and the network loss is known to be high. This

mode differs from the Dynamic mode in that it uses

aggressive encoding as soon as it detects

HP Velocity at the far end without first measuring

the loss in the network.

Burst Loss Protection Auto Set Burst Loss Protection (BLP) to protect against

correlated loss in the network.

Options are:

• Off: Disables BLP for correlated loss.

• Active: Enables BLP for correlated loss.

• Auto: Allows the HP Velocity Device Driver to

determine if BLP is needed and automatically turn

on processing if required.

BLP Buffer (ms) 20 ms Set the amount of packet buffering in milliseconds

that HP Velocity can use when protecting against

correlated loss.

Values range from 10 ms to 100 ms in increments of

10 ms.
