5.3. Network Segmentation
It's very likely that at some point you'll have to break up one large network into a bunch of smaller ones because user response will have dwindled to a slow crawl as the network grew and grew. With all that growth, your LAN's traffic congestion will have reached epic proportions. So, now I'm going to show you how to use the segmentation devices I have defined so far in this chapter.
Here's a list of some of the nasty things that commonly cause LAN traffic congestion:
Too many hosts in a broadcast domain
Adding hubs for connectivity to the network
The answer to fixing a huge but slow network is to break it up into a number of smaller networks—something called network segmentation ...
