Although UUCP may be a reasonable choice for low-cost dial-up network
|
||
|
links, there are many situations in which its store-and-forward
|
||
|
technique proves too inflexible, for example in Local Area Networks
|
||
|
(LANs). These are usually made up of a small number of machines located
|
||
|
in the same building, or even on the same floor, that are interconnected
|
||
|
to provide a homogeneous working environment. Typically, you would want
|
||
|
to share files between these hosts, or run distributed applications on
|
||
|
different machines.
|
||
|
<P>
|
||
|
These tasks require a completely different approach to networking.
|
||
|
Instead of forwarding entire files along with a job description, all
|
||
|
data is broken up in smaller chunks (packets), which are forwarded
|
||
|
immediately to the destination host, where they are reassembled. This
|
||
|
type of network is called a <em>packet-switched</em> network. Among other
|
||
|
things, this allows to run interactive applications over the network.
|
||
|
The cost of this is, of course, a greatly increased complexity in
|
||
|
software.
|
||
|
<P>
|
||
|
The solution that system--- and many non- sites--- have
|
||
|
adopted is known as TCP/IP. In this section, we will have a look at its
|
||
|
underlying concepts.
