QoS

QoS is a suite of features that configure queuing and scheduling on
the forwarding path of your ERX system. QoS provides a level of predictability and control beyond the current best-effort service.
Your ERX system provides best-effort data delivery by default. Packets not assigned to a specific traffic class are carried in the best-effort traffic class. Best-effort service provides packet transmission with no guarantee of results.

The major QoS features that the ERX system provides are:

• Multiple traffic classes
• Configurable scheduling
• Configurable buffer management

For information on configuring QoS, see ERX Policy Management and QoS Configuration Guide, Chapter 2, Configuring Quality of Service.
