<div><p>This is the first type of outbound bandwidth policy you can create
|
||
|
|
on your server. Differentiated service divides your traffic into classes.
|
||
|
|
To carry out a differentiated service policy, you need to determine how you
|
||
|
|
want to classify your network traffic and how to handle the different classes.</p>

||

<li class="ulchildlink"><strong><a href="rzak8classes.htm">Prioritized classes: How to classify network traffic</a></strong><br />
|
||
|
|
Differentiated service identifies traffic as <em>classes</em>. The
|
||
|
|
most common classes are defined using client IP addresses, application ports,
|
||
|
|
server types, protocols, local IP addresses, and schedules. All traffic that
|
||
|
|
conforms to the same class is treated equally.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="rzak8handle.htm">Setting priorities: How to handle the classes</a></strong><br />
|
||
|
|
After traffic is classified, differentiated service also requires a per-hop behavior to define how to handle the traffic.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="rzak8conditioners.htm">Traffic conditioners</a></strong><br />
|
||
|
|
To use quality of service (QoS) policies, network equipment (like routers and switches) must have the capability for traffic conditioners. Traffic conditioners refer to classifiers, meters, markers, shapers, and droppers.</li>
