Implementing differentiated services, including IPQoS, on a network requires extensive planning. You must consider not only the position and function of each IPQoS-enabled system, but also each system's relationship to the router on the local network. The following task map lists the major planning tasks for implementing IPQoS on your network.
| Task | Description | For Instructions | 
|---|---|---|
| 1. Plan a Diffserv network topology that incorporates IPQoS-enabled systems. | Learn about the various Diffserv network topologies to determine the best solution for your site. | |
| 2. Plan the different types of services to be offered by the IPQoS systems. | Organize the types of services that the network provides into service-level agreements (SLAs). | |
| 3. Plan the QoS policy for each IPQoS system. | Decide on the classes, metering, and accounting features that are needed to implement each SLA. | |
| 4. If applicable, plan the policy for the Diffserv router. | Decide any scheduling and queuing policies for the Diffserv router that is used with the IPQoS systems. | Refer to router documentation for queuing and scheduling policies. |
