Layer 2 virtual private networking (VPN) services over MPLS (Multiprotocol Label Switching) include Virtual Private LAN Services (VPLS) and Virtual Private Wire Services (VPWS).
These services enable Layer 2 VPN service offerings in a simple manner that is easy to deploy and operate. Layer-2 VPN services, based on a combination of Ethernet and MPLS/IP technologies, are designed to enable service providers to offer Business Ethernet private line services. These services use a simple Layer 2 interface at the customer edge and benefit from the resilience and scalability of an MPLS/IP core.
VPLS provides a virtual LAN between multiple locations. VPWS provides a virtual dedicated line between only two locations.
