| Data type | Range | Default value |
|---|---|---|
| REG_DWORD | 0 | 1 | 1 |
Determines whether QoS priority boosting is enabled on this interface. QoS boosts traffic priority only when RSVP signaling is disabled.
Priority boosting increases the link-level priority of GQoS application traffic to the priority of the service level the program requests. Traffic priority determines the order in which packets are submitted to the network when it is congested.
You can use this entry to priority of traffic without signaling.
| Value | Meaning |
|---|---|
| 0 | The link-level traffic priority of GQoS application traffic is not elevated, regardless of its service type. The traffic maintains the same priority level as other best-effort traffic. |
| 1 | The link-level traffic priority of GQoS application traffic is elevated to the priority of the service level the program requests. |
Note
Windows 2000 does not add this entry to the registry. You can add it by editing the registry or by using a program that edits the registry.
To determine this setting a particular QoS interface, add the EnablePriorityBoost entry to an interface-specific <Interface-name>\Qos subkey in Tcpip\Parameters. If this entry appears in both the Qossp subkey and an <Interface-name>\Qos subkey, the value in the <Interface-name>\Qos subkey takes precedence over the value in the Qossp subkey when configuring that interface.
Caution
Consider the effect of priority boosting carefully before enabling it. Priority boosting is not subject to policy or admission control.
