HP mt40 Mobile manual LiveQ configurable parameters

Using the Management Application				Configuration
	Table 22. LiveQ configurable parameters
	Configuration option	Description
	Global Target Loss Rate	Specify the loss rate that HP Velocity will attempt to achieve for all active
		HP Velocity-protected flows.
		Available values are 0.04%, 0.1%, 0.2%, and 0.4%. The default is 0.04%.
		NOTE: Aggressive target loss rates might not be achievable in very high-
		loss networks or bandwidth restricted environments.
	Congestion Avoidance	Congestion Avoidance analyzes network links. It detects links with
		bandwidth constraints and automatically adjusts HP Velocity protection to
		accommodate the bandwidth constraint.
		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.
		Available values are enabled or disabled. The default value is enabled.
	Bandwidth Control	Specify the range of protection modes that HP Velocity is able to use when
		encoding HP Velocity-protected flows.
		The protection mode defines how protected flows are protected from
		network loss. Higher protection modes protect against a greater network
		loss but also require more bandwidth.
		HP Velocity constantly monitors network loss and automatically selects the
		protection mode required to reduce the network loss to the specified TLR.
		The selection process is dynamic and the mode used at any given time
		depends on the real-time loss measured in the network.
		Available modes are:
		•	Dynamic: Use this mode in situations where bandwidth is not
			constrained. It will maximize performance while minimizing the required
			bandwidth. Dynamic is the default mode.
		•	Low: Use this mode in very 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.
