Virtual Private LAN Service (VPLS)
What is VPLS?
VPLS, standing for Virtual Private LAN Service, is a type of VPN (Virtual Private Network) technology that enables the connection of multiple geographically dispersed Ethernet LANs over a shared IP or MPLS network. Unlike traditional VLANs (Virtual LANs) which are confined to a single physical switch, VPLS extends the LAN concept across a large WAN (Wide Area Network), essentially creating a "virtual" extension of the local network across the broader infrastructure.
How does a VPLS work?
VPLS, standing for Virtual Private LAN Service, is a type of VPN (Virtual Private Network) technology that enables the connection of multiple geographically dispersed Ethernet LANs over a shared IP or MPLS network.

Benefits of VPLS:
- Simplified LAN Extension: Extends LAN services across geographically dispersed locations like branches and remote offices.
- Improved Flexibility and Scalability: Allows for dynamic addition and removal of sites compared to dedicated circuits.
- Cost-Effectiveness: Reduces costs compared to leasing dedicated lines between locations.
- Enhanced Security: Encapsulated traffic ensures secure communication across the shared network.
- Unified Network Management: Simplifies management of geographically distributed LANs through a single interface.
Who uses VPLS?
VPLS is popular among organizations with geographically dispersed locations, particularly those requiring secure and efficient LAN extension for:
- Enterprise branch offices
- Retail chains
- Educational institutions
- Healthcare organizations
- Financial institutions
