Title : Fast Handoff L2 Trigger API
Author(s) : A. Singh et al.
Filename : draft-singh-l2trigger-api-00.txt
Pages : 16
Date : 2002-10-10
To enable seamless L3 handover of a MN from one subnet to other, the
MN or the AR is required to anticipate the identity of the target AR
prior to initiation of the L3 handoff. To anticipate the identity of
target AR, the L3 is required to receive a notification from L2 about
the appropriate identity of target AP as soon as the L2 handoff is
detected. To further optimize the L3 handoff, L3 is also required to
receive indications about Link Up and Link Down events as soon as
such events are detected by L2. The Link Down event is detected by L2
as soon as the MN loses connection with current AP. Similarly, the
Link Up event is detected as soon as the MN re-connects with new AP.
Depending upon the nature of access technologies, some of the various
triggers can be available at MN, AR or both.

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
