Class of Service Feature Guide (Routers and EX9200 Switches)

 

Use this guide to understand and configure class of service (CoS) features in Junos OS to define service levels that provide different delay, jitter, and packet loss characteristics to particular applications served by specific traffic flows. Applying CoS features to each device in your network ensures quality of service (QoS) for traffic throughout your entire network. This guide applies to all Juniper routing devices and EX9200 switches.
