Title : Fast Handoff by L2 Trigger in MPLS-based Mobile IP Networks
Author(s) : Y. Kuang, et al.
Filename : draft-kuangyj-l2trigger-mpls-mip-00.txt

This document extends the integration of Mobile IP (MIP) and Multi-
Protocol Label Switch (MPLS) with Layer2 Triggers (L2T) to expedite
handoff and route optimization procedures. In the proposal, MPLS
acts as only a fast second layer switch technique to setup a
connection-oriented communication network, while MIP or IP acts as a
signaling protocol to operate, administrate and manage MPLS network.
L2Ts in this proposal are introduced to trigger signaling process of
rerouting, extension and recovery of label switch paths (LSP) rather
than to trigger registration or binding update of new care-of
address (CoA), in traditional MIP. Moreover, in the proposed
architecture, IP-in-IP tunneling is replaced by LSPs to support
mobility, which reduces packet overhead thus mitigates network
burden and makes it easy to support quality-of-service (QoS) or
class-of-service (CoS). Therefore, the proposed scheme is well
suited for time-constrained or delay-sensitive applications.

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
