Virtual Private LAN Service - Definition from the Hotspot Shield Glossary

A VPLS is a service that allows a business to create a logical LAN network between locations that a geographically separate. For example an office in New York and New Jersey could apply for a VPLS through a telecom carrier and if implemented, the two offices could interact as if they were in the same location.

Traffic through a VPLS uses the MPLS protocol (Multiple Label Switching) which creates a pseudo VPN at each location in the network. VPLS can transport non-IP data, and provide point-to-point connectivity - It effectively acts like a virtual switch that connects multiple remote networks or devices together. A VPLS will either be configured by the telecom carrier or the businesses networking team.
