Enhanced Transmission Selection (ETS) is a network scheduling algorithm that allows the switch to assign different priority and bandwidth values to different traffic classes. This can be useful for transmitting traffic to servers that have different requirements for latency, jitter, or throughput. For example, ETS can prioritize voice or video traffic over data traffic, or allocate more bandwidth to backup or replication traffic. ETS is configured using the Data Center Bridging Exchange (DCBx) protocol, which advertises the configuration to peer devices. Therefore, implementing ETS on an ArubaOS-CX switch is a valid use case for enabling the switch to assign the correct priority and bandwidth to traffic that it transmits to servers.
