Virtual Local Area Networks (VLANs) provide a way to logically segment a single physical LAN into multiple broadcast domains, which can have different security policies, broadcast domains, and quality of service (QoS) settings. VLANs provide the following benefits:
Increased Network Security: VLANs can provide an increased level of network security by separating sensitive data traffic from other network traffic. By segmenting the network into smaller broadcast domains, access to specific resources can be more easily controlled and monitored. This can prevent unauthorized access to sensitive data, and limit the impact of any security breaches that do occur.
Improved Bandwidth Utilization: VLANs can improve the use of available bandwidth by allowing many logical networks to share the same network infrastructure. VLANs allow administrators to group devices that communicate frequently with each other, reducing the amount of traffic that needs to be sent across the network. This can improve the performance of the network and reduce the amount of congestion on the network.
Better Broadcast Management: VLANs can help to mitigate broadcast storms by decreasing the number of broadcast domains, thus increasing their size. By isolating broadcast traffic to specific VLANs, the impact of broadcast storms can be minimized. VLANs can also help to reduce the amount of unnecessary broadcast traffic on the network by limiting broadcasts to only those devices that are part of the same VLAN.
In summary, VLANs provide several benefits that can help to improve the security, performance, and management of a network. By isolating traffic into logical broadcast domains, VLANs can provide increased security, more efficient use of available bandwidth, and better management of broadcast traffic.
