MPLS VPN - Point-to-point (pseudowire)

Point-to-point (pseudowire)

Point-to-point MPLS VPNs employ VLLs (virtual leased lines) for providing Layer2 point-to-point connectivity between two sites. Ethernet, TDM, and ATM frames can be encapsulated within these VLLs. Some examples of how point-to-point VPNs might be used by utilities include encapsulating TDM T1 circuits attached to RTUs or forwarding non-routed DNP3 traffic across the backbone network to the SCADA master controller.
