>Packet protocols like IP or IPX rely upon the receiver host knowing
|
|
where the start and end of each packet are in the data stream. The
|
|
mechanism used to mark and detect the start and end of packets is
|
|
called <I
|
|
CLASS="EMPHASIS"
|
|
>delimitation</I
|
|
>. The Ethernet protocol
|
|
manages this mechanism in a LAN environment, and the SLIP and PPP protocols
|
|
manage it for serial communications lines.</P
|
|
><P
|
|
>The comparatively low cost of low-speed dialup modems and telephone circuits
|
|
has made the serial line IP protocols immensely popular, especially for
|
|
providing connectivity to end users of the Internet. The hardware required
|
|
to run SLIP or PPP is simple and readily available. All that is required is
|
|
a modem and a serial port equipped with a FIFO buffer.</P
|
|
><P
|
|
>The SLIP protocol is very simple to implement and at one time was the more
|
|
common of the two. Today almost everyone uses the PPP protocol instead. The
|
|
PPP protocol adds a host of sophisticated features that contribute to its
|
|
popularity today, and we'll look at the most important of these later.</P
|
|
><P
|
|
>Linux supports kernel-based drivers for both SLIP and PPP. The drivers
|
|
have both been around for some time and are stable and reliable. In
|
|
this chapter and the next, we'll discuss both protocols and how to
|
|
configure them.</P
