Abstract: This document discusses considerations for assigning a new recommended Differentiated Services Code Point (DSCP) for a standard Per-Hop Behavior (PHB). It considers the common observed re-marking behaviors that the Diffserv field might be subjected to along an Internet path. It also notes some implications of using a specific DSCP.
