   Precongestion notification (PCN) is a means for protecting quality of
   service for inelastic traffic admitted to a Diffserv domain. The
   overall PCN architecture is described in RFC 5559. This memo
   describes the requirements for the signaling applied within the PCN
   domain: (1) PCN-feedback-information is carried from the PCN-egress-
   node to the decision point;(2) the decision point may ask the PCN-
   ingress-node to measure, and report back, the rate of sent PCN-
   traffic between that PCN-ingress-node and PCN-egress-node. The
   decision point may be either collocated with the PCN-ingress-node or
   a centralized node (in the first case, (2) is not required). The
   signaling requirements pertain in particular to two edge behaviors,
   "controlled load (CL)" and "single marking (SM)".
