VLAN (Virtual Local Area Network) is a technology that segments a physical network into multiple, distinct logical networks. This allows devices on separate VLANs to communicate as if they were on different physical networks, even though they share the same hardware infrastructure.
Key Features:
- Segmentation: Groups devices logically based on function, department, or security requirements, rather than their physical location.
- Enhanced Security: Isolates traffic between VLANs, reducing the risk of unauthorised access or data breaches.
- Efficient Management: Simplifies network management by reducing broadcast traffic within each VLAN.
Benefits:
- Improved Performance: Minimises network congestion by isolating traffic.
- Cost Savings: Uses existing infrastructure to create logical network segments without additional hardware.
- Flexibility: Easily reconfigures network segments through software without changing physical connections.
In summary, VLANs enhance network efficiency, security, and scalability by logically separating traffic within a shared physical network.
