Many of todayÆs networks use PPP as a means of providing access
links to remote users. In case a PPP user is mobile and performs a
subnet handover, it needs to tear down and re-establish of its PPP
link with the network. PPP link re-establishment is an elaborate
procedure (as explained in a later section of this document)
involving multiple messages. This will lead in an extended service
disruption as due to the round trip time involved in the messaging
as well extensive radio bandwidth usage. Of this reason, we
consider PPP to be a prime candidate for context transfer [1-3].
The proposal in this document can reduce the number of PPP
establishment messages by 50%-100. Furthermore, it will save
significant amount of time in PPP state machine transitions, due
to the multiphase nature of PPP. Reliability and timing issues of
PPP context transfer are also discussed.

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
