Differentiated service

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.

• Prioritized classes: How to classify network traffic
  Differentiated service identifies traffic as classes. 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.
• Setting priorities: How to handle the classes
  After traffic is classified, differentiated service also requires a per-hop behavior to define how to handle the traffic.
• Traffic conditioners
  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.
