connection? </p>
|

<div class="section"><p>PPP is a standard Internet connection. PPP allows interoperability
|
||
|
|
among the remote access software of different manufacturers. PPP also allows
|
||
|
|
multiple network communication protocols to use the same physical communication
|
||
|
|
line.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><p>PPP replaces Serial Line Internet Protocol (SLIP) as the protocol
|
||
|
|
of choice for point-to-point connections. The SLIP Request for Comment (RFC)
|
||
|
|
never became an Internet standard because of the following deficiencies: </p>
|
||
|
|
<ul><li>SLIP has no standard way to define IP addressing between the two hosts.
|
||
|
|
This means that an unnumbered net cannot be used.</li>
|
||
|
|
<li>SLIP has no support for error detection or error compression. Error detection
|
||
|
|
or error compression is implemented in PPP.</li>
|
||
|
|
<li>SLIP has no support for system authentication, while PPP has two-way authentication.</li>
|
||
|
|
</ul>
|
||
|
|
</div>
|
||
|
|
<div class="section"><p>SLIP is still used today, and is still supported on the iSeries™ server.
|
||
|
|
However, IBM<sup>®</sup> suggests
|
||
|
|
that you use PPP when setting up point-to-point connectivity. SLIP provides
|
||
|
|
no support for Multilink connections. Compared to SLIP, PPP has better authentication.
|
||
|
|
PPP performs better because of its compression facilities. </p>

connection profiles that are defined with ASYNC line types are no longer supported
