Title : PPP Adaptation for Cellular Networks
Author(s) : K. Purser
Filename : draft-purser-pppext-pppcn-00.txt
Pages : 9
Date : 2003-9-17
If the Internet is accessed via cellular networks, the Point-to-Point
protocol (PPP) is most commonly used for configuration of the
circuit-switched or packet-switched link. Thus, this PPP
configuration time comes in addition to the usual call-setup time for
the cellular connection. In many cases this will result in a fairly
long 'wait time' as perceived by end users before actual application
data can be transmitted.
This proposal describes a solution in which the PPP configuration
time can be significantly reduced (on the order of seconds) in cases
where both peer protocol entities can be modified according to this
proposal, which involves modifying standard PPP. In cases where one
PPP peer is modified and the other utilizes only standard PPP, the
modified peer can fallback to standard PPP operation. This fallback
mechanism will not noticeably affect the PPP setup time, and serves
to ensure interoperability.

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.
