# Providing QoS for Triple Play Traffic on E Series Routers, Release 11.2.0

By configuring quality of service (QoS) in a triple-play network, service providers can optimize bandwidth and prevent network latency and jitter in the data, voice, and video services that they offer to subscribers.

This page provides information about the JUNOSe software features that you can use to configure QoS for triple-play networks on E-series routers. In particular, this page focuses on configuring queuing and shaping properties for Ethernet interfaces using QoS parameters.
