Quality of Service (QoS)

Quality of Service (QoS) is a general term that is applied to mechanisms used to treat traffic
streams with different relative priorities or other delivery characteristics. Standard QoS
mechanisms include IEEE 802.1D/Q (Ethernet frame priority) and Differentiated Services
(DiffServ) in the TCP/IP protocol suite.
The QoS Object provides a means to configure certain QoS-related behaviors in EtherNet/IP
devices.
