RFC 3175 defines aggregate Resource ReSerVation Protocol (RSVP)
reservations allowing resources to be reserved in a Diffserv network
for a given Per Hop Behavior (PHB), or given set of PHBs, from a
given source to a given destination.  RFC 3175 also defines how
end-to-end RSVP reservations can be aggregated onto such aggregate
reservations when transiting through a Diffserv cloud.  There are
situations where multiple such aggregate reservations are needed for
the same source IP address, destination IP address, and PHB (or set of
PHBs).  However, this is not supported by the aggregate reservations
defined in RFC 3175.  In order to support this, the present document
defines a more flexible type of aggregate RSVP reservations, referred
to as generic aggregate reservation.  Multiple such generic aggregate
reservations can be established for a given PHB (or set of PHBs) from
a given source IP address to a given destination IP address.  The
generic aggregate reservations may be used to aggregate end-to-end
RSVP reservations.  This document also defines the procedures for such
aggregation.  The generic aggregate reservations may also be used
end-to-end directly by end-systems attached to a Diffserv network.
