Class of Service

The Class of Service menu allows you to configure most of the Junos OS CoS components for the IPv4 and MPLS traffic on a J Series or an SRX Series device. You can configure forwarding classes for transmitting packets, define which packets are placed into each output queue, schedule the transmission service level for each queue, and manage congestion using a random early detection (RED) algorithm. After defining the CoS components, you must assign classifiers to the required physical and logical interfaces.
