Implementation - VLAN (1)
Switches bring high performance and easy administration
Virtual LAN (VLAN) technology solves the problem of broadcast floods in switching network by segmenting it into smaller domains (broadcast traffic is contained within these domains)
VLAN is a collection of workstations grouped by logic instead of geography
Routers interconnect VLANs and filter out unnecessary broadcasts between them. Inter-VLAN communication can be controlled by access lists and traffic filters
Design and management of VLANs can be an administrative nightmare
