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.
