A method used to implement QoS in IP networks. A three-bit field in the ToS byte of the IP header (RFC 791). Using IP Precedence, a network administrator can assign values from 0 (the default) to 7 to classify and prioritize types of traffic. IP Precedence is being phased out in favor of DSCP (Differentiated Services Code Point), but is supported by many applications and routers.
