Virtual Local Area Networks 2 There are times when a simple LAN grows unexpectedly and many changes reduce the functionality of the LAN. In the case of this company, bandwidth issues and security issues may be solved with the implementation of a VLAN. A VLAN allows computers in multiple geographical locations to operate and share resources as if they were in one LAN. This allows computers to operate more efficiently and utilize bandwidth more economically and increase security. The network should be segmented into four different broadcast domains, one for each department. This plan will allow increased bandwidth for each domain. Each broadcast domain that is created is its own VLAN separating each and allowing faster communication from one device on a VLAN to another (Regan, 2004). Information will not have to travel to a centralized switch that decides where the data goes. Instead, each device on a VLAN communicates with the others directly. A VLAN will allow for improved security as well. As a VLAN separates devices into broadcast domains, there will be limitations on devices trying to access data on domains it does
