QOS Policy
A
Policy
sets behavioural attributes of the traffic matched by a collection of rules. This is the defining
part of the HFSC queue, which regulates packet sending by applying complex algorithms based on the
latency and bandwidth available. The rules, or Policy Rules are also defined in the policy. These policies
can be added by clicking on
Add
button next to
Add Policy
. Each policy includes the following
configurable fields:
Field
Description
Enable
To enable or disable the policy.
Label
Plain text used to name the policy.
Weight
A portion of the combined policy weights of a binding. The larger the weight (with respect
to the other policy weights), the larger portion of the maximum bandwidth is available. For
example, if a binding contains three (3) policies, each policy contains a weight of 10.
Therefore the traffic matching each policy will be 1/3 of the total interface bandwidth.
Latency The maximum delay in the transmission of related packets. The lower the latency, the
faster the packets will be scheduled for transmission.
Default
Specifies whether the policy is a fall-back policy, i.e. the policy used for traffic that is not
matched by a policy rule. If unchecked, custom policy rules can be defined. It is critical to
define a default, otherwise any packets that do not match a rule will be dropped.
QOS Rule
The
Rule
specifies the types of packets that will inherit the parent policy's attributes. Rules can be
added by first unchecking
Default
, then click the
Add
button next to
Add Rule
. Each rule includes the
following configurable fields:
