Enhanced Transmission Selection (ETS) is a traffic management feature defined in the IEEE 802.1Qaz standard. It helps network devices like switches and routers manage how different types of traffic share bandwidth on a single physical link. ETS works alongside other standards like Data Center Bridging (DCB) to improve performance in environments where multiple traffic classes, such as storage, voice, and video, compete for resources.
At its core, ETS allows administrators to assign minimum bandwidth guarantees to different traffic classes. This ensures that critical applications always get the resources they need, even when the network is busy. ETS also supports bandwidth sharing when some traffic classes are idle, helping to make the most of available capacity.
This guide describes ETS and how to configure it.
