Now we apply VLAN technology to configure the system shown as the figure
above. We can partition the users into the different logical networks which have their
own broadcast domain. The traffic will not disturb among these logical networks.
The users 1x (x denotes a ~ d) are members of VLAN 1. Any traffic within VLAN 1
does not flow to VLAN 2 and others. This helps us configure the network easily
according to the criteria needed, for example, financial, accounting, R&D and
whatever you think it necessary. You can also easily move a user to a different
location or join a new user somewhere in the building to VLAN. Without VLAN, it is
very hard to do. Basically, VLAN can afford offering at least 3 benefits: move and
change users, reduce broadcast traffic and increase performance, Security.
Besides, VLAN can highly reduce the traffic congestion and increase total
performance because there are no more too many users in the same broadcast
domain.
