Switching Implementation Package |
A
LAN switch is a device that provides much higher port density at a
lower cost than traditional hubs. For this reason, LAN switches can
accommodate network designs featuring fewer users per segment, thereby
increasing the average available bandwidth per user.
Recent LAN switches are evolving
to multi-layer devices
capable of handling protocol issues involved in high-bandwidth applications
that historically have been solved by routers. Today, LAN switches
are being used to replace hubs in the wiring closet because user
applications are demanding greater bandwidth.
LAN switches incorporate Virtual
LAN (VLAN) technology which allows a group of devices on one or
more LANs that are configured (using management software) so that
they can communicate as if they were attached to the same wire,
when in fact they are located on a number of different LAN segments.
Because VLANs are based on logical instead of physical connections,
they are extremely flexible.
