Through VLAN switching and routing, a physical network of devices can be segmented into multiple domains. VLAN is short for virtual local area network. It is also called a Virtual LAN. The computers, servers and other devices on a VLAN perform virtually as if on a single LAN, even if they’re in separate locations. The VLAN divides a local network into distinctive segments for:
- Voice over IP;
- Network management;
- Storage Area Network (SAN);
- Guest network;
- Demilitarized zone (DMZ).
VLAN implementation can facilitate network management by supporting supports scalability, enhanced security, improved efficiency, and modification flexibility. Virtual Local Area Network switches allow separated computers and users to communicate in a simulated environment as if they are sharing one broadcast and multicast domain.
VLAN Trunking with VTP Connections
Switches can communicate with each other using VLAN trunking with VTP connections. The proprietary VLAN Trunk Protocol (VTP) allows individual switches to be efficiently managed as a group even though they are on different LAN segments. The protocol supports improved network performance and reduced administration.
Communication can be achieved through the VLAN trunking connection using a router. Managed switches deliver VLAN routing options for business which are often easily administered.
Virtual Local Area Networks Designed for Performance
The devices on one or more LANs can be configured for communications as if they were physically connected. Using Virtual Local Area Networks, administrators can control devices and expand capabilities to achieve improvements in traffic load management and performance. Network traffic can be segmented for efficient flows, with critical traffic receiving priority status. A switch with VLAN features can be configured to logically group devices together and isolate traffic between groups.
