Getting Started with HP-UX IPQoS

HP-UX IPQoS Deployment Components

The Role of Policies

Policies are used to decide what happens to selected classes of traffic. Policies work to translate business-level goals into specific operational behaviors. Tailor your policies to address specific traffic management issues.

HP-UX IPQoS policies can specify reservation bandwidth (dedicated minimal percentage of available), maximum allowed bandwidth (percentage for non-reserved bandwidth when available), DSCP field marking, and VLAN priority marking.

The reservation bandwidth rate specifies the rate you want to assure traffic can access when the network is congested. If you want this rate to increase unbounded during uncongested periods, do not specify a maximum bandwidth value. If you want to limit the traffic to a specific rate even when there is no congestion, then specify a maximum bandwidth rate.

The reservation and maximum bandwidth rates assigned to traffic classes must take into account the total bandwidth available on the local network to which the HP-UX IPQoS system is attached. The percentage of the reservation bandwidth can not exceed 100% (100%-80Kbps for HP-UX IPQoS).
