What is the modern name for the IPv4 Type of Service field, and what does DSCP stand for?

Explanation:
Modern IPv4 QoS uses the Differentiated Services Field. This 8-bit field carries a 6-bit DSCP value and a 2-bit ECN value; the DSCP portion selects the Per-Hop Behavior a router should apply to the packet, while ECN signals congestion without dropping packets. DSCP stands for Differentiated Services Code Point. This pairing—the Differentiated Services Field and the expansion DSCP as Differentiated Services Code Point—is the correct, current naming. The old label Type of Service is obsolete, and terminology like Traffic Class Field isn’t used for IPv4 in this context.
