Technical Summary

   This document extends Generic Aggregated RSVP functionality (see
   RFC 4860) in order to support admission control for Pre-Congestion
   Notification (PCN).

   Experimental RFC is requested because this is new functionality
   for which implementation and usage experience is desired
   before producing a proposed standard.  The title page header
   indicates the intended Experimental status.

Working Group Summary

   The document spent a while in the WG.  As a result of WG Last
   Call, the PCN admission control decision point was moved from the
   ingress node to the egress node in order to better match RFC 4860
   functionality, and RSVP admission control is no longer performed
   for the end-to-end reservation wrt the aggregate reservation for
   the PCN domain, as PCN admission control at the egress node suffices.

Document Quality

   Francois LeFaucheur
   and Bob Briscoe reviewed during WG Last Call, and provided comments
   that resulted in significant improvements.
   RSVP Directorate Review was performed by Scott Bradner.  There are
   no known implementations due in part to the significant
   changes made as a result of WG Last Call.
