Title : Extensions to Resource Reservation Protocol (RSVP) for Mobile IPv6
Author(s) : Y. Sun, et al.
Filename : draft-sunyi-fast-rsvp-01.txt
Pages : 59

RSVP [1] is designed as a signaling protocol that provides end-to-end
QoS guarantee for real-time services in the fixed hardwired network.
However, when used in the mobile environment, the protocol doesn't
work well due to the mobility of the endpoints. Immediately after a
handover occurs, because of the lack of resource reservation in the
handoff target subnet, QoS of the session degrades notably. Another
problem is that when route optimization is implemented,the protocol
will be invalidated due to certain features of the route optimization
mechanism.
This document proposes extensions to RSVP. The extensions enable
RSVP to operate in the mobile IPv6 network while providing advanced
resource reservation before handover and resource reservation on the
optimized route after handover. With these features, QoS of the
sessions can be guaranteed and the utilization of network resources
can be enhanced resulting in the improvement of overall network
performance.

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
