System Administration Guide: IP Services

General IPQoS Configuration Planning (Task Map)

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 and links to procedures to complete the tasks.



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). 

Planning the Quality-of-Service Policy.

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.
