Planning for Quality of Service
Effective use of Quality of Service (QoS) capabilities requires careful planning. 
Before you deploy QoS to your network, carefully consider the types of 
applications used in the network and which QoS techniques might improve the 
performance of those applications. Then, use CiscoWorks QoS Policy Manager 
(QPM) to create and deploy your QoS policies to the network, and analyze QoS 
performance. 
The following topics introduce you to QoS concepts and QoS capabilities 
supported by QPM:
Planning for QoS Deployment
The process of planning and implementing QoS is cyclical, and requires the 
following steps:
1.
Identify the application traffic in your network:
Identify the applications in the network, and the traffic distribution of 
these applications. For example, you might identify the following 
applications—SAP (10% of traffic), HTTP (30%), FTP (20%), Voice 
over IP (VoIP) (30%), and other applications (10%).
Identify the business critical applications. In our example these might be 
SAP, Intranet HTTP, and VoIP.
