Title : RSVP Proxy Approaches

RSVP signaling can be used to make end-to-end resource reservations
in an IP network in order to guarantee the QoS required by certain
flows. With conventional RSVP, both the data sender and receiver of
a given flow take part in RSVP signaling. Yet, there are many use
cases where resource reservation is required, but the receiver, the
sender, or both, is not RSVP-capable. This document presents RSVP
Proxy behaviors allowing RSVP routers to perform RSVP signaling on
behalf of a receiver or a sender that is not RSVP-capable. This
allows resource reservations to be established on parts of the end-
to-end path. This document reviews conceptual approaches for
deploying RSVP Proxies and discusses how those can synchronize RSVP
reservations with application requirements. This document also
points out where extensions to RSVP (or to other protocols) may be
needed for deployment of a given RSVP Proxy approach. However, such
extensions are outside the scope of this document. Finally,
practical use cases for RSVP Proxy are described.

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.
