VPWS

Virtual Private Wire Service

Virtual Leased Lines (VLL) is a way to provide Ethernet-based point to point communication over IP/MPLS networks.

The term Virtual Leased Line is also used to describe a point to point bonded connection using the Broadband Bonding technology. This implementation is bonded in layer 4.

In the industry, the technology is also referred to as Virtual Private Wire Service (VPWS) or EoMPLS (Ethernet over MPLS).

VLL uses the pseudo-wire encapsulation for transporting Ethernet traffic over an MPLS tunnel across an IP/MPLS backbone.
