Today switches are an ideal solution to most kinds of local area network
congestion problems.
VLAN (Virtual Local Area Network)
A VLAN is a group of end-stations that are not constrained by their physical
location and can communicate as if on a common broadcast domain, a LAN.
The primary utility of using VLAN is to reduce latency and need for routers,
using faster switching instead. Other VLAN utility includes:
Security: Security is increased with the reduction of opportunity
in eavesdropping on a broadcast network because data will be
switched to only those confidential users within the VLAN.
Cost Reduction: VLANs can be used to create multiple broadcast
domains, thus eliminating the need of expensive routers.
Port-based (or port-group) VLAN is the common method of implementing a
VLAN, and is the one supplied in the Switch.
