This memo describes a technique for dynamically discovering the maximum precedence (MPrec) of an arbitrary internet path. It specifies a small change to the way that routers generate one type of ICMP messages. For a path that passes through a router which does not implement this change, this technique may not necessarily discover the correct Path MPrec. In this case, an application which desires to make use of a non-zero precedence should degrade gracefully.
