With the class-of-service (CoS) features on a J-series Services Router, you can assign service levels with different delay, jitter (delay variation), and packet loss characteristics to particular applications served by specific traffic flows. CoS is especially useful for networks supporting time-sensitive video and audio applications. To configure CoS features on a Services Router, see Configuring Class of Service.
This chapter contains the following topics. For more information about CoS, see the JUNOS Class of Service Configuration Guide.
