Network administrators now have a new tool in their arsenal as they work to increase network efficiency and minimize operational costs. Using virtual local area networks, or VLANs, network administrators can segment network traffic and layer intelligence and prioritization over those segments to meet the connectivity needs of every department as well as business leaders.
VLANs, an extended benefit of software-defined networking (SD-WAN), breaks down how users connect to the network at large. With VLANs, network segmentation that previously required hardware with multiple physical WAN ports, can now be defined using a single physical WAN, virtually. Network administrators can create virtual network ecosystems for each department or device type, prioritizing business critical applications as needed.
Key Benefits of Using VLANS

For example, in a medium-sized company with a headquarter location and two branch offices, network administrators can create VLANs at each branch office as needed to support the needs of each location. Point of Sale devices, that are always a priority to maintain connectivity to support the business operations, will be prioritized to ensure business continuity. Whereas, the guest WiFi users will be a lower priority, and also have restricted access to the internet only (no internal systems access). Thirdly, computers and WiFi LAN that need connectivity to specific businesses applications to be efficient, will be optimized above other general network traffic.
