Larger  business computer networks  often set up VLANs to re-partition their network for improved traffic management.

VLANs are intended to group together client devices that communicate with each other most frequently. The traffic between devices split across two or more physical networks ordinarily needs to be handled by a network's core  routers , but with a VLAN that traffic can be handled more efficiently by  network switches  instead.
