Understanding LAN Switching
Today’s LANs
- Mostly switched resources; few shared
- Routers provide scalability
- Groups of users determined by physical location
When we look at today's LANs, the ones that are most commonly
implemented today, we're looking at mostly switched infrastructures, because of
the price point of deploying switches, many companies are bypassing the shared
hub technologies and moving directly to switches.Even within switched networks,
at some point we still need to look to routers to provide scalability. And also
we see that in terms of the grouping of users, they're largely determined by the
physical location.So that's a quick look at traditional shared LAN technologies.
What we want to do now, since we know those limitations, we want to look at how
we can fix some of those issues. We want to see how we can deploy LAN switches
to take advantage of some new, improved technologies.
