A key problem in the design of RSVP version 1 is, as noted in
its applicability statement, that it lacks facilities for
aggregation of individual reserved sessions into a common
class. The use of such aggregation is required for
scalability.
This document describes the use of a single RSVP reservation
to aggregate other RSVP reservations across a transit routing
region, in a manner conceptually similar to the use of Virtual
Paths in an ATM network. It proposes a way to dynamically
create the aggregate reservation, classify the traffic for
which the aggregate reservation applies, determine how much
bandwidth is needed to achieve the requirement, and recover
the bandwidth when the sub-reservations are no longer
required. It also contains recommendations concerning
algorithms and policies for predictive reservations.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
